5 CHAPTER 2 Quick Start 2.1 Board Description The Matrix module is a 2.4GHz 802.15.4 data transceiver module based on the Chipcon CC2430 Low Power 8051/Transceiver device. It provides enhanced range performance with either a 10mW or 100mW* power amplifier. The module also contains an integrated PCB trace antenna. Power is supplied by the host device through the interface connection in accordance to the operating voltage requirements with a nominal operating voltage of +3.3V. Exact details on the interface connections and messaging are available in the Matrix Electrical Interface Control Drawing. Figure 2-1. Top-Side of RF 10mW Matrix Module Figure 2-2. Top Side of Matrix 10mW Interface Board * Operation is Limited to 10mW Maximum for European Union Compliance
62.2 Operational Overview The quick start demonstration presented in this chapter is referred to as the ping pong test. The ping pong test allows an end user to easily verify communication between two transceivers and get a feel for the quality of the link via feedback of the flashing LEDs. Operation involves two boards, with one designated as a master device and the other as a slave device. The master periodically transmits packets to the slave. If the slave receives and verifies the packet, it will flash its LEDs and transmit an acknowledgement to the master. If the master receives and verifies the acknowledgement, it will flash its LEDs. In normal ping pong mode, LEDs indicate signal strength (two LEDs on indicate high signal strength, one LED indicates low signal strength). If the LEDs do not light, the packet or acknowledgement was not received. 2.2.1 Power Up Insert batteries into interface boards and verify that battery supply is selected using the jumper as shown in Figure 2-3 below (J43 1-2, J18 4-6, J16 5-6, J16 9-10, and J36 1-2). Figure 2-3. 10mW RF Matrix Module and Interface Board
72.2.2 Master/Slave Selection Master device setup: 1. Press reset button (S1), see Figure 3-1 location 5, and user button (S3), see Figure 3-1 location 6, on Interface Board simultaneously. 2. Release reset button (S1) on Interface Module. 3. Wait until yellow LED (LED2) is lit, then release reset button (S1). Slave device setup: 1. Press reset button (S1) and user button (S3) on Interface Board simultaneously. 2. Release reset button (S1) on Interface Module. 3. Quickly release the user button (S3) (Release within 1.5 seconds of performing step 2 above). 2.2.3 Association Mode In association mode, the red LED (LED3) will flash rapidly on each board until it has linked with the other device. At this point, the red LED (LED3) will go out and the yellow LED (LED2) will begin to flash rapidly for approximately two seconds. Association mode lasts up to thirty seconds after power up, so the master and slave pair should be powered up at relatively the same time. If the transceivers link, they will enter the ping pong mode after association mode times out. However, if they do not link, they will not communicate and the sequence must be repeated from the point of master/slave selection at power up. 2.2.4 Ping Pong Mode In ping pong mode, the master and slave boards will flash one or two LEDs with each packet (slave) or acknowledge (master) received, based on message signal strength. Refer to Table 2-1 below for a description of the LEDs versus signal strength. In case there is a lot of traffic on the default channel, it is possible to change the channel. Red LED Yellow LED Signal Strength Off Off None Off On Marginal On Off Good On On Excellent Table 2-1. LED Signal Strength Definitions
82.2.5 Channel Changing (can only be peformed if boards have been associated) While in the ping pong mode, the current channel can be changed to one of four other unique channels (four channels total). This is accomplished by holding the push button for approximately two seconds, at which point the yellow LED (LED2) will be lit steady. Once the push button is released, the current channel option number (one through four) is displayed by a series of flashes on the red LED (LED3). Each short push button press will increment the channel option number and display it with a given number of flashes on the red LED (LED3). To accept the last selected channel, hold the push button until the yellow LED (LED2) goes out (approximately two seconds). After again releasing the button, the device will return to the ping pong mode. Note that both the master and slave devices must be set to the same channel option number for the pair to communicate, and each board must be individually set to that given channel option number.

15CHAPTER 4 Software Overview 4.1 Software Description The Matrix evaluation software was designed to give the developer an ability to quickly test the features built into the Matrix module. The evaluation software is described in the following sections. A screen shot of the evaluation software is shown in Figure 4-1. Developers please refer to Chapter 5 for information on building custom applications for use on the Matrix module. Figure 4-1. Evaluation Software - Main Screen
164.2 Software Setup Prior to installing the test tool, power the Matrix module and connect up either the RS-232 serial communications or USB communications cable. Refer to Section 3 above for the correct jumper settings for each the power supply connection and communications connection that will be used (Jumpers J17 11-12 and J17 15-16 should be installed, jumper J40 1-2 is for USB or J40 2-3 is for RS-232, and jumper J18 3-4 is for bench supply, J18 2-4 is for USB communications supply, or J18 4-6 is for battery supply). Note that when using the USB communications connector and cable that a virtual serial COM port is created that should show up in the “Communications Settings” dialog shown in Figure 4-2 below. Install the Evaluation test tool using the self extracting setup program and execute the MatrixTT.exe to start the program. If the bottom status bar as shown in Figure 4-1 shows a COM port number and a baudrate, then connection with the module has been successful and you can skip to Section 4.2.1. If the bottom status bar shows “Comm Port: None”, then the test tool was not able to find a Matrix module on any of the available PC COM ports. Pull down the “Settings” menu and click the “Communications” entry. The screen shown in Figure 4-2 will appear. Figure 4-2. Communication Setup Screen under “Settings” Pull Down Menu The default baudrate is set to 19,200 baud, so leave that setting alone. Determine serial port in use and select “OK”. Next click the “Get Version” button on the bottom of the test tool to verify communication with the device. If the version does not appear, verify correct COM port and select “OK” and verify communication successful. Another option if the COM port in use is not known is to select “Auto Detect”. If “Auto Detect” is successful the status bar should show a comm port number and a baudrate. If communication is still unsuccessful with the Matrix module, verify all jumper settings, restart test tool, and perform steps outlined above.

294.3 Setting Up and testing a Wireless Link Operational testing of the Matrix RF module requires at least 2 units in order to establish a link. One unit will be the initiator and the other will be the responder. In order for a link to be established it is necessary to setup the transceiver’s RF Channel, long or short address, and PAN ID. Link testing may be performed in either a single ended or a round trip fashion. This can help to differentiate between real world packet error performance and raw radio performance. If Acknowledgement settings are not used then it is a single-ended test, if Acknowledgements are enabled then it is a round trip test. 4.3.1 Single-ended Test Single ended performance will require 2 computers, since it will be necessary to read the statistics from each radio. An example setup is outlined below. Device 1 (Refer to Figures 4-10 and 4-12) 1. Set PAN ID to 100 (IDs Page). 2. Set Short Address to 1 (IDs Page). Note to use long addressing set short address to 65,535. 3. Disable Acknowledgements/Retries (RF Settings Page). 4. Disable Receive All RF Messages (RF Settings Page). 5. Set to RF Channel 23 (RF Settings Page). 6. Set transmitter power setting to 31 (RF Settings Page). 7. Set Short Destination address to 2 (Located Upper left corner of TT). 8. Select Short Address Radio Button (Upper Section of TT). *Long may be selected if sending to a long address device. 9. Select “Save Config To NV Memory” Command Button (Upper Section of TT). 10. Check the Show Received box (Upper Section of Test Tool).
30Device 2 (Refer to Figures 4-11 and 4-12) 1. Set PAN ID to 100 (IDs Page). 2. Set short address to 2 (IDs Page). Note to use long addressing set short address to 65,535. 3. Disable Acknowledgements/Retries (RF Settings Page). 4. Disable Receive All RF Messages (RF Settings Page). 5. Set to RF Channel 23 (RF Settings Page). 6. Set transmitter power setting to 31 (RF Settings Page). 7. Set Short Destination address to 1 (Located Upper left corner of TT). 8. Select Short Address Radio Button (Upper Section of TT). *Long may be selected if sending to a long address device. 9. Select “Save Config To NV Memory” Command Button (Upper section of TT). 10. Check the Show Received box (Upper Section of Test Tool). Figure 4-10. ID Settings for Device 1

32Operational Description Place the 2 units in physically separate locations and apply power to them. The statistics will clear when power is cycled, but they will need to be cleared manually after each test if power is not cycled. Connect each individual PC serial port to each of the units and verify the correct destination address is typed in the address field on the top of the test tool. Type a short message into the “RF Data” window of the initiating device. The message can be any text or numbers. If no message is entered it will not be possible to transmit. Set the “Repeat Delay” to 100 msec if it isn’t already set. Click the “Send Single Repeated Msg” button to start transmission. The radio will send messages repeatedly with 100mSec in between messages until the “Stop Repeat” button is clicked. Allow the test to run for some convenient amount of time and then stop transmission. Go to the “Statistics” screen of the initiating device and select the “Query Statistics” command button and record the packets sent in the Transceiver section of the test tool. Next select “Query Statistics” on the receive device and record packets received in the Transceiver section of the Statistics page. Link success is simply the ratio of the “Packets Received” to the “Packets Sent”. This test will give the raw performance of the link in one direction without retries. It is a good indicator of the RF environment in which the radios are being used. High levels of noise or other products operating in the 2.4 GHz band can cause lower packet success rates. 4.3.2 Round Trip Test To test the ability of the system to retry messages in a noisy environment, it is necessary to use a round trip test where the remote end can acknowledge receipt of packets. Use the setup screen as shown in Figure 4-10 thru 4-12 for each respective device, but enable acknowledgements on both devices (Refer to RF Settings Page). Perform the test in the same manner as the single ended test. Run enough transmissions to get a statistically valid sampling of the radio environment over a reasonable period of time. Look at the “Statistics” screen on the initiating radio to find the total number of packets sent. Link quality is displayed in the Pkt Success Rate w/Acks text box. Total link success is the ratio of “Acks Received” to “Packets Sent”.
33CHAPTER 5 Matrix/Zigbee Ready Module Input/Output 5.1 Overview There are a total of 12 user input/output pins on the Matrix module, all of which can be configured as digital inputs or outputs. Of the 12 configurable digital I/O pins, 8 of them can also be configured as analog inputs. 5.2 Digital Inputs/Outputs There are 12 configurable digital input/output pins that can be programmed to be either inputs or outputs. In addition, if the pins are inputs, all except for two (P1_0 and P1_1) of them can be enabled for either an internal pull-up or pull-down resistor. Refer to Table 4-2 for the specific I/O pin capabilities. Using the digital input output pins consists of the following: Configuring the pins Select direction (digital input or digital output), enable or disable pull-up or pull-down resistors for pins configured as digital inputs, and set the initial output value for pins configured as digital outputs (0 or 1). These parameters define the configuration of the pins when a reset occurs. Also the direction and pull-up/pull-down parameters are used to set the state of the pins after exiting sleep mode. Note that if the internal pull-up or pull-down resistors are used that all pins within the same port have to either be pull-ups or pull-downs. Configuring the sleep state of the pins Select direction (input or output), enable or disable pull-up or pull-down resistors for pins configured as digital inputs, and set the output value for pins configured as digital outputs. Although these parameters are the same as those shown in the “Configuring the pins” item shown above, they are independent and are the state of the pins when the Matrix module is put into Sleep Mode. Reading the state of the pins configured as inputs Read the digital value (0 or 1) of the signal applied to the pins configured as inputs. Setting the state of the pins configured as outputs Set the digital value (0 or 1) for the pins configured as outputs.
345.3 Analog Inputs There are 8 pins that can be configured as analog inputs. Refer to Table 4-2 for the specific I/O pin capabilities. Using the analog input pins consists of the following: Configuring the pins Select direction as analog input. Select the analog-to-digital converter settings for each specific pin configured as an analog input (refer to Section 4.2.7). Configuring the sleep state of the pins Select direction (input or output), enable or disable pull-up or pull-down resistors for pins configured as digital inputs, and set the output value for pins configured as digital outputs. Note that pins configured as analog inputs under normal operating mode can be set as anything when the Matrix module is put into Sleep Mode. Reading the state of the pins configured as analog inputs Read the analog value of the signal applied to the pins configured as inputs. The voltage on the analog input pins is determined by the following equations. These equations take into account the “reference voltage” and “resolution” from the “Analog Input ADC Settings”. The “Analog Input ADC Settings” can be set and queried from the module using host messages 0x25 (Set Analog Input ADC Settings) and 0x26 (Query Analog Input ADC Settings). 8 Bit Resolution Analog Input Voltage = (Analog Value / 128) x Reference Voltage 10 Bit Resolution Analog Input Voltage = (Analog Value / 512) x Reference Voltage 12 Bit Resolution Analog Input Voltage = (Analog Value / 2048) x Reference Voltage 14 Bit Resolution Analog Input Voltage = (Analog Value / 8192) x Reference Voltage
35CHAPTER 6 Matrix Application Guide 6.1 Overview This Chapter describes the essentials for using the host protocol to configure and use a Matrix module in an application. Please refer to Host Protocol Document for Further Details on messaging. 6.1.1 Host Protocol The host protocol that is used to communicate with a Matrix module is a simple binary based protocol. Every message in the protocol consists of a header, a trailer, and potentially some payload information, which is consistent with other LSR module data packet structures. With the Matrix module it is possible to configure the baudrate from 1.2k up to 115.2, and as such it uses a DMA peripheral in conjunction with the UART so that reliable data transfers are possible at the higher data rate. In order to simplify operation of the DMA peripheral when used with the UART, all messages sent to and received from the Matrix module should additionally have the “Length” byte repeated as the first byte in a packet (prior to the header). The header is made up of a start byte (0x01), a length byte that is the length of the entire message including header and trailer, and a message type that identifies the intention of the message. The payload varies from message to message but in general includes things such as data to be sent or received, or configuration information. The trailer is made up of a checksum, which the sum of all of the bytes in the message, starting at the start byte (0x01) and up through the payload, and an end byte (0x04). Note that the checksum computation does not include the additional “Length” byte that precedes the start byte. Every message that the host device sends to the Matrix module has a complimentary acknowledgement message that will get sent back upon successful decoding and processing by the Matrix module. 6.1.2 Configuration After power-up or after receiving a “Reset Request” (type 0x18) message, the Matrix module will read the configurable parameters from the on-board microcontroller’s non-volatile FLASH memory, and store them in RAM to be used from that point on. Changing a parameter by sending the module a new message does not automatically result in the module saving the parameter to non-volatile memory, but rather just changes the value stored in RAM. This allows a particular host application to change the configurable parameters dynamically without unnecessarily writing to, and shortening the lifetime of, the non-volatile memory. All of the Matrix module’s configurable parameters that are stored in RAM can be saved to non-volatile memory by sending a “Save Configuration Values to Non-Volatile Memory” (type 0x11) message.
36Communication Parameters There are six configuration parameters used to setup the Matrix module for communications, which are outline below. 1. Set PAN ID – The Personal Area Network (PAN) ID is used to establish networks of transceivers. Only devices with the same PAN ID will communicate with one another. 2. Set Transceiver Address – The Transceiver Address is used to differentiate transceivers within a network. Each transceiver should be configured with a different address. The Transceiver Address consists of both a short two byte and a long eight byte address. Setting the short address to 65,534 (0xFFFE) will cause the Matrix module to use its long address. To use the short address, the short address should be set to between 0-65,533. 3. Set RF Channel – The RF channel is used to select the channel in the 2.4GHz band that the transceiver will operate on. Communication between transceivers is only possible if the devices are both using the same RF channel. Valid RF channels are from 11 (2405MHz) to 26 (2480MHz). 4. Enable/Disable Receive All RF Messages (Feature Currently Not Available) – Enabling receive all RF messages allows all messages on the configured PAN ID to be received by the Matrix module. This intended use of receive all messages is for diagnostics tools so that it is possible to see all messages on a network. Note that when this mode is enabled that it is not possible to transmit RF messages. 5. Enable/Disable RF Acknowledgements and Retries – When RF Acknowledgements and Retries are enabled, the destination transceiver will respond to the received RF message with an RF acknowledgement. If the source transceiver does not receive an RF acknowledgement, it will attempt to re-send the message to the destination transceiver up to 3 more times (3 retries). By using acknowledgments and retries, the likelihood of successfully getting a message from one transceiver to another increases. 6. Set Transmit Power Level – This setting allows for adjusting the transmit power, which affects the overall range. The range varies from 0 to 31. Input/Output Parameters There are three configuration messages used to setup parameters for controlling the user input and output pins, which are outlined below. 1. Set I/O Configuration – This message is used to configure the direction (input or output), whether or not the internal pull-up or pull-down resistors are enabled for pins configured as inputs, and the initial output value for pins configured as outputs. The initial output value is the default state that output pins will be assigned after power-up or a “Reset Request” command is issued to the module.
372. Set I/O Sleep State – This message defines the state that the I/O pins will be put into when the low power sleep mode of operation is requested for the module. Similar to the “Set I/O Configuration” message, the direction of the pin, whether or not the pull-up or pull-down resistors are enabled for input pins, and the output value for output pins can be configured. Upon exiting sleep mode the pins will be configured back to the state they were in prior to entering sleep mode. 3. Set Analog Input ADC Settings – This message is used to set up how the ADC conversion will be done for pins configured as analog inputs. The settings include the reference voltage that the conversion is based on, the resolution of the ADC conversion, and the number of samples to average when a reading is taken. Note that the higher the ADC conversion resolution the longer it takes to do a conversion.
38Diagnostics and Feedback Parameters There are two configuration parameters used to setup diagnostics and user LED feedback which are outlined below. 1. Set Debug Mode – Setting the debug mode allows the host application to configure what debug information gets displayed on the three mode pins when the mode pins are in their default state. The default state for the mode pins is that none of the pins are externally pulled-down. The intent of the debug signals is to allow for monitoring on an oscilloscope how the device is operating. 2. Set LED Functionality – This message is used to configure if any LED feedback information is enabled or not, and if it is enabled what it represents. For modules that are embedded in an enclosure, the LED functionality can altogether be disabled to further reduce power consumption. Several examples of the types of functionality that can be displayed on the LEDs are a heartbeat LED flash to indicate the microcontroller is running or flashes when an RF or serial message is either transmitted or received. Multiple functions can be enabled simultaneously. The LED functionality can be enabled on pins P0_0 and P0_1 or on P0_2 and P0_3, or it can be disabled altogether and then the pins can be used as user I/O. If LED functionality is enabled for use on P0_0 and P0_1, either LEDs can be populated on the Matrix modules itself, or off board LEDs can be utilized. When LED functionality is enabled for use on P0_2 and P0_2, then it is required that off board LEDs be used. Example configuration The following example will show details of what host protocol messages a host device would send to a Matrix module to configure all of its programmable settings. After all of the settings have been sent to the transceiver, save configuration parameters message is issued to save the settings to non-volatile memory. Settings PAN ID: 100 Transceiver Address: Long Address = 500 (short address needs to be 65,535) RF Channel: 18 Receive All: Disabled Acknowledgements and Retries: Enabled Transmit Power Level: 31 (maximum) I/O Pin Configuration: All inputs with pull-up resistors enabled I/O Pin Sleep State: All inputs with pull-up resistors enabled (unchanged) Debug Mode: Disabled LED Functionality: Heartbeat and flash on RF activity, LED activity on pins P0_0 and P0_1

Save Configuration Parameters To Non-Volatile Memory < 0x05 0x01 0x05 0x11 0x17 0x04 > For all of the messages shown above that would get sent from the host application to the Matrix module, a host level acknowledgement will be sent back when it has been successfully processed. It is recommended that the host application send a message to the module and then wait for an acknowledgement response prior to sending the next message. This will take care of flow control and prevent the host application from overflowing the module.
406.1.3 RF Messaging Overview The Matrix module provides a versatile command set for communications between modules. Depending on the application’s requirements, either short or long address modes can be used. Short addressing mode uses a two byte transceiver address, while long addressing mode uses eight byte transceiver addresses. It is also possible to communicate between transceivers using mixed addressing modes, hence a message can be sent from a transceiver with a short address to another transceiver with a long address or vice versa. There is a single host message that is used to send data from one transceiver to another and two host messages that are generated when a message is received. When in receive all (Feature Not Available) mode of operation and a message is received by a transceiver, host message type 0xA9 is generated and sent out the serial port to the host. In the default mode of operation (receive all mode disabled) host message type 0x95 is generated and sent out the serial port to the host. RF host messages consist of a standard header (start, length and type), RF message header, payload, and a standard trailer (checksum and stop). The RF message header contains a Packet ID, a Target/Sender identifier, an Address Mode byte, and the Transceiver Addresses. The Packet ID is used to identify each message and should be incremented for each new packet when sending a message. The Target/Sender byte indicates where the message originated from and is being sent to. Messages either are originated from or sent to either the host or the application. The application is the user application code that is running on the Matrix module (currently not supported). The host is the host application. The Address Mode byte describes the type of addressing for the particular message. The upper nibble indicates the addressing mode used for the destination of the message, while the lower nibble indicates the mode for the source of the message. A 0 is used to represent a short address, while a 1 represents a long address. Following the Addressing Mode is the destination address and then the source address (for received messages only – types 0x95 and 0xA9). Short Addressing In order to use short addressing it is required that the transceiver address be set between 0 and 65,533 (0xFFFD). Setting the short address to 65,534 (0xFFFE) causes the transceiver module to use the eight byte long address. Long Addressing Long addressing mode is configured by setting the short address to 65,534 and then selecting a long address in the range of 0 to 18,446,744,073,709,551,614 (0xFFFFFFFFFFFFFFFE). Broadcasts It is possible to broadcast a message to all transceivers configured to the same RF channel and PAN ID. Messages are broadcast by sending the message to the short destination transceiver address 65,535 (0xFFFF).
41 Receive All (Feature Currently Not Available) Receive all mode is used as a diagnostic mode in which a transceiver can listen to and receive all of the messages from any device that is communicating on the same PAN ID and RF channel. Messages with long and short addressing types will be received, and when a message is received it is sent out the host serial port with a message type of 0xA9. In receive all mode it is not possible to transmit messages to other transceivers. Addressing Modes Summary The Table 6-1 below gives an overview of the addressing modes that are available in the Matrix module. The table shows a summary of what happens when messages are sent between two modules (Transceiver A and Transceiver B) using the various addressing modes (short and long), and also broadcasts. The first column “Host Send Mode” lists what type of message the host would send to the Matrix module into transceiver A. The “Addressing Mode” columns show what type of address (short or long) each transceiver is configured to use. Upon transceiver A receiving the message from the host device, transceiver A would then send a message over the RF link to transceiver B using the type of address shown in the first column. If transceiver B successfully receives the RF message from transceiver A, then a host message is generated that will be sent from transceiver B to the host connected to transceiver B. The messages that get generated will have the source and destination addresses contained in it which are shown in the table under the “Host Receive Mode” columns. A dash (-) denotes that a message was not received by the transceiver because the destination address for transceiver B was not the same type (short or long) as the destination address type to which the message was sent (shown in the first column). It is assumed that the destination address to whom the message is being sent is the same as that address for which the receiving transceiver is configured to use.

Addressing Overview Note 1: Since a transceiver is setup with both a long and a short address, if long addressing is being used (short address = 65,534) and a message is being sent to the transceiver with a short address of 65,534, a RF acknowledgement will be sent by the MAC. Note 2: Since a transceiver is setup with both a long and a short address, if short addressing is being used (short address not equal to 65,534) and a message is being sent to the transceiver with a long address that matches the transceiver’s long address, a RF acknowledgement will be sent by the MAC.
436.1.4 Example Messaging For all of the following examples it is assumed that the PAN ID and RF channel are set to be the same on both Matrix modules. Also the messages will originate in the host connected to transceiver A and they will be sent to transceiver B. The data contained in the message will be 0x01, 0x02, 0x03. All received messages have a Link Quality Indication (LQI) of 200 (0xC8).

Below is a more detailed description of each of the messages with examples showing the corresponding host messaging. 1. Set Digital Pin Output State – This message is used to write the values of the digital output signals. Two bytes containing a bit mask for each digital output signal is sent in a host message to the Matrix module. Only user pins configured as digital outputs contain any meaningful information. A zero indicates a low signal is applied to the output, while a one indicates a high signal is applied. Example: Digital Outputs = P0_7, P0_4, P1_6, and P1_0. Digital Output P0_7 = 1 Digital Output P0_5 = 0 Digital Output P1_6 = 0 Digital Output P1_0 = 1 Host -> Matrix Module – (Set Digital Pin Output State – Type 0x20) < 0x07 0x01 0x07 0x20 0x80 0x01 0xA9 0x04 > Matrix Module -> Host – (Set Digital Pin Output State Acknowledged– Type 0xA0) < 0x05 0x01 0x05 0xA0 0xA6 0x04> 2. Query Digital Pin Input State – This message is used to read the values of the digital input signals. A bit mask for each digital input signal is returned in a host message that gets sent back from the Matrix module. Only user pins
46configured as digital inputs contain any meaningful information. A zero indicates a low signal is applied to the input, while a one indicates a high signal is applied. Example: Digital Inputs = P0_6, P0_5, P1_7, and P1_1. Digital Input P0_6 = 0 Digital Input P0_5 = 1 Digital Input P1_7 = 0 Digital Input P1_1 = 1 Host -> Matrix Module – (Query Digital Pin Input State – Type 0x21) < 0x05 0x01 0x05 0x21 0x27 0x04 > Matrix Module -> Host – (Respond With Digital Pin Input State – Type 0xA1) < 0x07 0x01 0x07 0xA1 0x40 0x02 0xEB 0x04 > 3. Query Analog Pin Values – This message is used to read the values of the analog input signals. The result is returned in a host message that gets sent back from the Matrix module containing a two byte value (LSB to MSB), for each of the eight potential analog inputs, with the 8, 10, 12, or 14 (depending on ADC conversion resolution) least significant bits representing the voltage applied to the inputs. Prior to reading the analog inputs the ADC conversion settings need to be set as described in Section 4.2.7. Note that the most significant bit of the conversion result is the sign bit. Example: ADC Settings: 1.25v Reference 10 Bit Resolution Average 1 Reading Analog Input P0_7 = 0.42v (10 bit value => 172 = 0x00AC) Analog Input P0_6 = 1.07v (10 bit value => 438 = 0x01B6) Host -> Matrix Module – (Query Analog Pin Values – Type 0x22) < 0x05 0x01 0x05 0x22 0x28 0x04 > Matrix Module -> Host – (Respond With Analog Pin Values – Type 0xA2) < 0x15 0x01 0x15 0xA2 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xB6 0x01 0xAC 0x00 0x1B 0x04>
