ZSTAR3 Sensor Board DescriptionZSTAR3 Reference Design Manual, Rev. 0.1Freescale Semiconductor 3-17 PreliminaryPreliminaryFigure 3-3. ZSTAR3 Sensor Board Software OverviewFor the Sensor Board operation, several of the MC13213’s hardware modules are used: Analog to Digital Converter (ADC), Synchronous Peripheral Interface (SPI), External Interrupt Request (IRQ), Keyboard Interrupts and General Purpose Input/Output (GPIO).3.2 Accelerometric sensor sw controllerReading of XYZ levels and all others operation with sensor is depends on current assembled sensor. The ZSTAR3 sensor board supports two types of Freescale accelerometric sensors, analogue(MMA736xLT) and digital(MMA745xL). Assembly sensor is powered by IO pins of MCU, this solution allow reach a lowest power consumtion in sleep mode.3.2.1 Double sensor support software modelAll common control functions of sensor are physically create as two individual function. First for analogue and second for digital sensor. Main software is using only volatile pointers on this function, that are assigned within initialization of program, by ” Recognise_Sensor() “ function. This function recognises an assembled sensor and assigns right functions address to volatile RAM pointers. For example, by this way analogue sensor is using ADC to read XYZ values of sensor and digital sensor is using digital interface, but in source code are only one line: p_Read_Accelerometer((void*) &(accel_data[0].x)).3.2.2 Autocalibration processThe software uses for both types of sensor autocalibration process to get offset calibration values. It uses a simple 0g X, 0g Y, +1g Z acceleration method. The sensor board runs autocalibration process for each g scale of sensor, and thus uses for each g scale induvidual set of calibration values.

These outputs are ratiometric which means that the output offset voltage and sensitivity will scale linearly with applied supply voltage. This is a key feature when interfacing to a microcontroller with A/D converter reference levels tied to a power supply, because it provides system level cancellation of supply induced errors in the analog to digital conversion process.During the analog-to-digital conversion in the microcontroller, 10-bit resolution is used. MC13213 A/D channels 0, 1 and 2 are connected to X (channel 1), Y (channel 2) and Z (channel 0) outputs of the MMA7360L. The microcontroller’s APCTL1 register enables these ADC channels for pin I/O control by the ADC module. The ADCCFG register controls the selected mode of operation, clock source, clock divide, and configuration for low power or long sample time.The MMA7360L sensor has implemeted digital output of freefall detection module. This output is connected direct to KBI(Keyboard interrupt module) and it’s used as default source of freefall detection.3.2.4 Digital sensor software supportThe MMA7450L provides a lots of various features, that almost are using by the ZSTAR3 demo. Complete communication with sensor is done by digital interface. MMA7450L supports two standards of digital comunication: SPI(Serial Peripherial Interface) and IIC(Inter-Integrated Circuit). 3.2.5 Power ManagementA CR2032 Lithium battery provides a fairly limited charge for such a realtime-like demo that demands frequent transmissions. Some sort of power management has to be implemented in order to keep the current consumption at a reasonable level. Typically, current consumptions of Sensor Board components are as follows:• SIP - System in Pack MC13213— 2.4GHz transceiver of MC13213 – in Off mode, 200nA– in Hibernate mode, 2.3µA– in Doze mode, 35µA– in Idle mode, 500µA– in Transmit mode, 30mA– in Receive mode, 37mA— 8-bit microcontroller of MC13213
ZSTAR3 Sensor Board DescriptionZSTAR3 Reference Design Manual, Rev. 0.1Freescale Semiconductor 3-19 PreliminaryPreliminary– in Stop3 mode, 700nA– in Wait mode, 560µA– in Run mode, 6.5mA• Triaxial accelerometers— low-g triaxial analogue Sensor MMA7360L– in Sleep mode, 3µA– in Normal mode, 400µA— low-g triaxial digital Sensor MMA7450L– in Sleep mode, 5µA– in Normal mode, 400µAIt is obvious that in a battery operated application care must be taken to ensure the lowest possible current consumption, especially when the maximum current (provided by the battery) is somehow limited. A CR2032 Lithium battery cannot provide current in the range of 40mA for long periods of time. To alleviate high current surges, an additional large capacitor has been designed.For transmission and reception using the MC13191, a specific scheme has been used to ensure the battery is not depleted or overloaded. Targeting a 30 samples per second (33ms period) transmission rate. For better power managment software using system of skiping transmission if sensor data are same or very similar as in previous trasmit sample. Maximum count of skip trasmission is 10, then sensor data are always transmitted and by this way is clear Timout timer in USB Stick. The ZSTAR3 typically open receive window each 10th period (~333ms) to keep synchronization with USB Stick (Communication Master) and for receive possible control data from master.The following scheme for one transmission/sleep cycle is used for the typically data transfer:Figure 3-4. Transmission/Sleep Cycle Details by basic 30Hz datarateAs shown on the previous diagram, all parts of the Sensor Board remain most of the time in Sleep/Doze/Stop modes, in which the total current consumption is below 10µA. timeReceived Master DozeMC13213 RF MODEM:StopMC13213 MCU:Run StopSensorbeingmeasuredTXRXNOT TO SCALEDozedatatransmittedPylon MessageSet up new messageand set RF modemRunPlan next RX window StopTrasmit time depends on sensor index
ZSTAR3 Sensor Board DescriptionZSTAR3 Reference Design Manual, Rev. 0.13-20 Freescale Semiconductor PreliminaryPreliminaryThe current consumption of the transmitter is ~30mA at that time, but only for a short period of time (typically ~600µs by 30Hz).In order to keep the Sensor Board informed on the status of connection (for example, if the data-receiving side - USB stick - is out of range, disconnected, etc.) and still synchronize with master, the reception has to be turned on after the data has been transmitted. This is not really required within each loop cycle, and in the actual implementation only on every 8th loop the receive window opens (receiver is enabled to receive the acknowledgment). More in Section 5.3, “ZSTAR3 RF Protocol description.The reception window is larger to fit any incoming receive data and the current consumption is also higher during reception, so this portion of current consumption would be one of the largest if the acknowledgment was received in every loop cycle.The “optional receive” feature allows huge power savings, still keeping the reception of acknowledgment data from the data-receiving side.Some further savings might be incorporated by utilizing the timer-triggered transceiver events that are described in the MC13213 Reference Manual.The MC13213, for example, latches a so-called time-stamp of each received frame. The data-receiving side read this value and trigger the acknowledgment sent at exactly specified time after reception (also, a start of data frame transmission can be programmed as timer-triggered). The Sensor Board then narrow its own receive window to perfectly match the expected time of the acknowledgment frame.3.2.6 MC13213 Modem Power Management FeaturesMC13213 modem provides several power saving modes. One of them is called Doze mode in which the MC13213 modem crystal oscillator remains active. An internal timer comparator is functional too, providing a power efficient and accurately timed way of waking-up the application after a specified time.This feature is fully utilized within the Sensor Board. The microcontroller calculates the time period for which the application should be in power saving mode, then fills in the timer comparator registers in the Modem, and the microcontroller goes into Stop mode (modem into Doze mode).Once the timer reaches the pre-programmed time (a timer compare occurs), the modem’s IRQ signal is asserted which brings the microcontroller out of the Stop mode. There are various scaling possibilities that allow periods from a few µs up to 1073 seconds (~17 minutes) to be programmed, without intervention of the microcontroller.3.3 ZSTAR Sensor Board Hardware OverviewThis section describes the Sensor Board in terms of hardware design. The MC13213 SIP drives only the analogue or digital triaxial sensor. Because for analogue and digital sensor is used only one footprint, thus has to be connected all necassary pins for both sensors and these connection has to be logical fit for both sensors.
ZSTAR3 Sensor Board DescriptionZSTAR3 Reference Design Manual, Rev. 0.1Freescale Semiconductor 3-21 PreliminaryPreliminary3.3.1 Sensors power supply Sensor are powered by IO pins of microcontroler. This can be done, because sensors consumed less than 0.5mA Three output pins together are used for analog VDD supply pin of sensor. This option hold down dynamically changes of voltage with different current consumption of sensor.Main feature of this solution is unbeatable currunt when complete board is in deep sleep mode (all board concum less than 1µA). Thus by this option the ZSTAR3 hasn’t to using sleep modes of sensors.ore details in section 3.3.1/3-Sensors power supply-213.3.2 Analogue sensor connectionThe MMA7360L Sensor outputs are connected to AD0, AD1, and AD2 inputs to analog-to-digital converter via RC filters formed by internal resistors in sensor and C13, C14, C15. These are recommended to minimize clock noise from the switched capacitor filter circuit inside the Sensor. Once the software filtering (also described in ) is employed, these RC filters may be completely omitted.The MMA7360L provides four next digital signals g-select, Self-test, 0g-detect and Sleep. All these pins are also routed to microcontroler, but only g-select and 0g-detect are use by software.3.3.3 Digital sensor connectionThe MMA7450L sensor are control by digital interface and two interrupts pins. Digital interface take a 4 wires, that provides both interfaces - IIC and SPI. These pins are routed to general IO pins and IIC microcontroler module, but board doesn’t provide external pull up resistors and thus can’t be used IIC module. This option saving a energy of battery in deep sleep mode.•pin 13 - SDA/SDO/SDI - IIC data, SPI data input/output•pin 12 - SDO - SPI data output•pin 14 - SCL/SPC - IIC clock, SPI clock•pin 7 - CS - Chip selectTwo interrupts pin called INT1/DRDY and INT2 are routed direct to KBI module of microcontroler. By this option software can be build on interrupts events. Signals use internal pull up resistors in microcontroler.•pin 8 - INT1/DRDY - interrupt 1 output, Data Ready output•pin 2 - INT2 - interrupt 2 outputWhen is digital sensor connected, then on footprints C13, C14 are placed 0R resistors. These two resistors grounded pin2 and pin4 of digital sensor.3.3.4 BDM (Background Debug Mode) ConnectionsA J2 connector is a non-standard footprint primarily intended for in-factory programming and testing via “spring-needle” type of connections. The J2 connector carries all standard signals for Background Debug Mode communication so if required, one may solder wires and a standard 2x3 pins 2.54mm (100mil) pitch

The pin numbering is shown on Figure 3-5. - BDM Connector LayoutFigure 3-5. BDM Connector Layout3.3.5 Button ConnectionsThree buttons (S1, S2 and S3) are connected directly to pins PTA0, PTA6 and PTA7. All have internal pull-up resistors, and are part of the Keyboard Interrupt module, therefore allow a direct microcontroller wake-up from the Stop modes.3.3.6 MC13213 RF InterfaceThe RF interface (antennas) were designed with the cost and board size in mind. Among several designs, the PCB layout antennas were in the main consideration (cost). Of several PCB antenna designs available for the 2.4GHz band (F-antenna, dipole, loop), the loop antenna has been selected mainly because of the size required on the PCB.The MC13213 transceiver provides a internal antenna switch of RF IN (receive) and PA OUT (transmit) paths, thus can be use a simple loop antenna.The antenna is designed as a “smile” layout , 10.7x24.3mm (420x960mils), made of 1.25mm (50mils) wide trace of copper.123456

L2 and L3 coils bias the transmitter output transistors to the CT_Bias level.The inductors used in this design are from TDK:• L1 (3.3nH) MLG1608B3N3DT• L2, L3 (22nH) MLG1608B22NJT3.3.7 Clocking Options of MC9S08QG8Due to the availability of accurate timing provided by the MC13213 internal transceiver, an internal oscillator (ICG) in the MC13213 microcontroler is used as the main clock source for the microcontroller. The protocol related timing is derived from RF modem timers, the microcontroller itself is clocked from an internal oscillator. Microcontroler clock run with 20MHz on bus.3.3.8 LED IndicatorOn the design is used only a one LED, because the ZSTAR3 board is designed to fit a plastic box, that has only a one position for light indicators. The LED is connected with current limiting serial resistor R1 direct to PTC5 microcontroler pin.3.3.9 Power SupplyThe Sensor Board is powered by a Lithium coin-sized battery. The primary choice was the popular CR2032.A surface mounted SMTU series battery holder from RenataTM is placed on the underside of the PCB. The SMTU series holders provide (by mechanical construction) battery reverse protection, so no additional circuitry is required.
ZSTAR3 Sensor Board DescriptionZSTAR3 Reference Design Manual, Rev. 0.13-24 Freescale Semiconductor PreliminaryPreliminaryA large tantalum capacitor (C1, 220µF/4V) improves the response of the power supply to current peaks caused by reception or transmission. Coin-sized Lithium CR2032 batteries are targeted at a maximum continuous discharge current in the range of 3mA. Such a large capacitor helps to supply enough current to the MC13213 during a receive/transmit without significant Vdd voltage drops.Design doesn’t have any main power switch, thus switch on is done by pressing any button on board and switch off is done by software (Timeout, Out of range, RF protocol command).3.4 Bill of MaterialsTable 3-1.

USB Stick software overview shows, in more detail, how different software and hardware modules co-operate with each other. There are two main tasks of the USB stick board:• receive the data from the MC13191 transceiver and store it in RAM buffer• handle the USB module communication, decode and provide the data from the RAM bufferThese two are somewhat independent and the only common point between them is the accelerometer and button data buffer in RAM. The RF software communicates with the Sensor Board and retrieves the latest accelerometer data. This is stored in RAM and can be independently read by the PC application via the USB link. The protocol employed on the PC side is just a subset of the Original ZSTAR that is build on simple STAR protocol used in the original RD3112MMA7260Q demo. The protocol is described in section Section 5.4, “ZSTAR3 USB protocol - Extended STAR protocol.For the USB stick board operation, several MCHC908JW32 hardware modules are used: USB 2.0 Full-speed (USB), Synchronous Peripheral Interface (SPI), Keyboard Interrupt (KBI) and a General Purpose Input/Output (GPIO).GPIOSPI USBRFProtocolHandlerLEDsMC13191RF modem2.4 GHzSMACPCProtocolHandlerSensors DataUSBdriverUSBport
ZSTAR3 Reference Design Manual, Rev. 0.1Freescale Semiconductor 5-31 PreliminaryPreliminaryChapter 5 Software Design5.1 IntroductionThis section describes the design of the ZSTAR3 software blocks. The software description comprises these topics:•5.2, “SMAC (Simple Media Access Controller) modifications description•‘Air’ 5.3, “ZSTAR3 RF Protocol protocol description•Serial 5.4, “ZSTAR3 USB protocol - Extended STAR protocol description• AN2295 5.6, “Bootloader (over USB) implementation notes5.2 SMAC (Simple Media Access Controller)The SMAC is a simple ANSI C based code stack available as sample source code which can be used to develop proprietary RF transceiver applications using the MC1319x, MC1321x.5.2.1 SMAC Features• Compact footprint:— 2K FLASH— 10 bytes (+ maximum packet length) RAM— As low as 16kHz bus clock• Can be used to demonstrate coin cell operation for a remote control• MC1319x/MC1321x compatible• Very-low power, proprietary, bi-directional RF communication link• ANSI C source code targeted at the HCS08 core and portable to almost any CPU core (including 4-bit)• Low priority IRQ• Sample application included, extremely easy to use• Liberally commented5.2.2 Modifications of SMAC for ZSTAR3 RF protocolThe development of the ZSTAR software is based on the free SMAC stack available from Freescale. The SMAC version used was 4.2. To SMAC has been added a three new targets files for Original USB Stick / Sensor and for new ZSTAR3 sensor board. Furthermore was add a couple of new function to this SMAC.
Software DesignZSTAR3 Reference Design Manual, Rev. 0.15-32 Freescale Semiconductor PreliminaryPreliminaryA fully detailed description of the SMAC is in the SMAC Reference Manual (SMACRM.pdf), available together with SMAC source code.5.2.2.1 New targets add to SMACModification of SMAC for individual application are done by targets files that exact defines all pins and peripheries. For ZSTAR3 project purposes has been added to SMAC three new targets:• MC1319XZSTAR_USB.c/h - these files describes Original ZSTAR USB Stick board• ZSTAR_SENSOR.c/h - these files describes Original ZSTAR and ZSTAR3 Sensor board• MC1321XZSTAR2.c/h - these files describes ZSTAR3 Sensor board5.2.2.2 New functions add to SMACOriginal SMAC doesn’t has implemented any advanced transceiver time operations as for example delayed trasmit / receive and others. On these functionalities is based ZSTAR3 RF protocol and thus had to be implemented. List of new functions in SMAC mac layer:• UINT32 MLMEGetActualTime(void) - function return actual value of free run main counter in modem• UINT32 MLMEGetTimeStamp(void) - function return time value of last received message• UINT32 MLMEComputeDelay(UINT32 u32StartTime, UINT32 u32Delay) - function compute new time with delay• UINT8 MLMEDelayTransceiver(UINT32 u32Time, UINT32 u32TimeOut, tTxPacket *psPacket,tRxPacket *psRxPacket, UINT8 u8mode) - main new function. This function provides delayed transmit, received with timeout, doze modes and general time interrupt5.3 ZSTAR3 RF ProtocolZSTAR3 uses a simple time based protocol for an RF transfer of information between Sensor Boards and USB receiver. ZSTRA2 RF protocol use simple star topology of communication net with one master point (USB Stick) and slaves(Sensor Boards). Protocol provides time slots up to 16 sensors. Main data load contents acceleration (X, Y and Z axis) and basic status data. The protocol is built on top of modified 5.2, “SMAC (Simple Media Access Controller) drivers that are available for the MC1319x and MC1321x transceivers family. The protocol is bidirectional allowing the set up of independent connections for a many of ZSTAR3 demos together in one RF space.All data is transferred in so-called Zpackets. This protocol is primarily targeted at simple demo purposes, allowing a fast transfer of the accelerometer data in short packets with minimum overheads and with minimum battery loads (most of the receive windows eliminated, short transmit packets, etc.).5.3.1 ZSTAR3 RF protocol features• Based on modified Freescale SMAC library• Star network topology• One coordinator of network (master)

The SMAC library transparently adds a 16 bit Packet control field (see chapter 7.2.1.1 of IEEE 802.15.4 Standard specifications) to differentiate packets from ZigBee and other standards.The Zpacket becomes a payload data for the SMAC standard packet and contains the following fields:•5.3.2.1, “Network Number(NetNum)•5.3.2.2, “RX Strength•5.3.2.3, “Zcommand•5.3.2.4, “ZdataFigure 5-1.

The USB Stick randomly generated it at the first time of lifecycle and it can be changed by command from PC. The new Sensor board has this number erased from manufacture and it can to update it when it received first valid packet in ZSTAR3 RF protocol format. Network Number in sensor board can be cleared by pressed all buttons during wake up sequency of board or it can be changed by command from USB Stick. It is used to determine between various connections. Packets with different Network numbers are simply ignored.This field is 16 bits long.5.3.2.2 RX StrengthThis field reports the strength of the last received packet on the other end of the connection. This value simply tells us how well the other side receives ‘our packets’. This can be used by transmission power management functions to change the transmission power if the other party receives packets with enough strength.The values reported are retrieved using the MLMELinkQuality() SMAC primitive.This field is 8 bits long.5.3.2.3 ZcommandThe ZSTAR demo protocol uses a few simple commands to establish and maintain the data flow between the Sensor Board and USB stick. The command is carried in 5.3.2.3, “Zcommand field and is 8 bits long.

The USB Stick is a master of the network and Sensor boards are slaves. All network runs within time based RF protocol, thus each device of the ZSTAR3 RF network has own time in each period for transmit. Receive time it’s little different, all Sensor Boards opens receive window in some time and tries to catch synchronization/data transmition of master, but USB Stick (master) has opened receive window all time when RF Sensor Boards transmits.The ZSTAR3 devices runs with simple state machine:1. Init state - Devices initialize all neccesarry hardware peripherials and software drivers. After initialization is done, state machine jumps to Broadcast state.2. Broadcast state: this is little bit outdated state that is keep in protocol only for compatibilities modes of ZSTAR3 protocol with original protocol devices.—Master (USB Stick) - the ZStar3 protocol needs only find out free channel for prepared RF network, but because the ZStar3 demo supports original ZStar RF protocol, then this state is important only for compatibility capatibilities of the ZSTAR3 demo.—Slave (Sensor board) - In this state the Sensor Board is looking for the ZSTAR3 communication. Ad when it’s found the RF communication with right NetNum number and its time position is free, jump to the Run State of RF protocol. If not jumps to the Sleep state.3. Compatibility state with original ZSTAR:
Software DesignZSTAR3 Reference Design Manual, Rev. 0.15-38 Freescale Semiconductor PreliminaryPreliminary—Master (USB Stick) - USB Stick of the ZSTAR3 supports original ZSTAR RF protocol and this state provide it. For ore details check Manual for original ZSTAR ZSTARRM Reference design manual - Original ZSTAR demo(RD3152MMA7260Q) RDM.—Slave (Sensor board) - Sensor board software conteins this state and it can support of original ZSTAR too, but all boards are ordered with prohibited compatibility.4. ZSTAR3 Protocol run state:—Master (USB Stick) - Master is periodically transmiting synchronization ZSTAR3_PYLON message and then receiving all incoming messages from the Sensor boards within same NetNum. In this state Master collect all neccessary information about connection status all Sensor Boards and other user payload.—Slave (Sensor board) - In this state slave is periodically opening window to receive Master synchronization mesage, measuring sensor data and tranmitting measured data with exact time offset to air(master).5. Sleep state:— Master (USB Stick) - Doesn’t have this state.— Slave (Sensor board) - When the Sensor Board goes this state, then switch off all peripheries on board and inside of microcontroller and prepare all board to at least power consumption.5.3.6.1 Typical one period of ZSTAR3 RF protocolThe ZSTAR3 RF protocol (in normal run mode) period starts by ZSTAR3_PYLON message from master. In ideal case all active slaves has opened receive window and catches incoming ZSTAR3_PYLON message from master. When sleves received this synchronization message, all in same time measure sensor output values and prepared future trasmition in unique time after ZSTAR3_PYLON message from master. This time is depend on index of each slave device. In the meantime the master prepared the new receive window and pens it before first prospektive message of Slave 0 and keeps opened this window until time
Software DesignZSTAR3 Reference Design Manual, Rev. 0.1Freescale Semiconductor 5-39 PreliminaryPreliminaryfor all 16 devices elapses. When the master catches any message from slaves, process it and immediatly open new receive window, if the last message wasn’t from 16th Slave device..Figure 5-3. ZSTAR3 RF protocol period5.4 ZSTAR3 USB protocol - Extended STAR protocolThe ZSTAR3 demo uses a subset of the original ZSTAR demo protocol commands.The Original ZSTAR is build on STAR demo protocol. This way, most of the software originally developed for the RD3152MMA7260Q (ZSTAR) and RD3112MMA7260Q (STAR) is also usable with the ZSTAR3.The STAR demo communicates over the RS232 serial line with a simple text-based protocol. The same protocol is used in ZSTAR/ZSTAR3 for communication between the USB stick and a PC (over a virtual serial port). The PC application sees the same interface (serial port) and the same protocol as if a STAR demo was connected.Because the ZSTAR3 can serve up to 16 connected sensor boards, all commands that works direct with sensor boards are communicated with one selected board by ‘N’ command from 5.4.3, “Subset of new added ZSTAR3 protocol commands.5.4.1 Subset of original STAR protocol commandsThe ZSTAR3 software contains all unchanged original STAR commands.
