Overview
This solution kit has been developed to demonstrate the combination of the Renesas wireless charging solution with the
chips RAA458100 (Tx) and RAA457100 (Rx) together with the Bluetooth Low Energy MCU RL78/G1D.
The kit consists of two boards, the Tx and the smaller Rx board. The boards are mounted together to retain the optimal
charging position. The Rx board can be used separately from the Tx board as long as the battery is full enough.

2.1
Host Adapter
The Tx board has an integrated host adapter. It consists of USB controller and I²C converter and replaces the
RTK0EF0029Z00001BJ host adapter. The firmware of the enclosed MCUs is identical with the original host adapter
firmware.
2.1.1
USB Controller
The RL78/G1C is the USB controller on the Tx Board. It converts the USB serial data from the PC into raw serial data
and vice versa. The USB interface allows the RWCE PC GUI tool to communicate with the Tx chip RAA458100. To
access this chip a dedicated USB driver is needed. For details please read chapter 6.
2.1.2
I2C Converter
The RL78/G14 converts the serial data stream into I²C packages that can be processed by the RAA458100 chip.
2.2
Bluetooth Module
The RL78/G1D is the central MCU on the RX board. It owns the Bluetooth Low Energy stack and collects the data
from the sensors and the heart rate module. The firmware is described in detail in chapter 4.
2.3
Heart Rate Module
The optional Heart Rate Module is the sensor board of the Pulse Meter Evaluation Kit described in R01AN3337EJ0100.
It can be attached easily and notifies the Bluetooth module via UART when new pulse data values are available. To
start the measurement a short impulse on the I/O line needs to be triggered. The communication protocol is described in
R01AN3338EJ0120.

Charging
The boards are configured by default to ATPC/AT1 mode. That means that the charging parameters are read from the
integrated EEPROM memory and the Rx chip will take care about the charging progress.
The battery on the Rx board can be charged when you follow these instructions:
•
In case you disassembled RX from TX board, then re-assemble it.
•
Have RX board switched ON (SW13).
•
Connect USB cable to TX board CN1 from a power supply, PC or Laptop.
•
Switch On the TX Board (SW14).
•
LED1 on TX board indicates by flashing start of wireless communication with RX Board.
•
Continuous lighting of LED1 indicates trickle charge / quick charge.
After the battery is fully charged, LED1 on TX board will turn off.
For further information on charging please read the Charge-It Quick Start Guide R19QS0001ED0100 and the User
Manual HW R19UH0104ED0100.
The Wireless Charging Solution Kit offers a PC GUI tool that can be connected to the Tx board and Rx board. With this
tool (RWCE_Tool) all relevant charging parameters can be setup to customer needs. For more information on this
please read chapter 6.
3.2
BLE Operation
After powering the Rx Board by switching SW13 to the “On” position the BLE module starts to send out advertising
packets until the device is connected.
The Rx board with the integrated sensors is intended to be used together with the Android Smartphone app “Charge-It”.
For installation and usage of this app please read chapter 5.1.

Sensors
The sensors.c module is the central sensor processing unit. It controls the 5 sub sensor entities
•
LIGHT
•
PRESSURE (and ambient temperature)
•
HUMIDITY
•
TEMPERATURE (IR sensor)
•
BATTERY VOLTAGE
After successful initialization the sensor values are collected by sensors_handler(). This hander is scheduled
permanently from the main loop. In case of a hardware defect the initialization function sensors_init() returns an error.
In this case the software stops the operation and remains in an error loop. The errors is visualized by a high-frequent
blinking of LED6.

User Manual Software
After the BLE connection is established a RWKE timer is started with period 300ms period. Each timeout all sensors
are triggered sequentially.
Light, pressure, ambient temperature, humidity and battery voltage values are stored in global accessible variables and
will be used as input for the BLE custom profile. For details please read chapter 4.3.5.
The BLE interface is handled by the module r_scp_app_ble.c. The sensor values are transferred to the BLE API each
second.
4.1.2
Heart rate monitor
The optional heart rate module is working self-sufficient. It is equipped with a RL78/I1E MCU which is connected to
the BLE Module by serial interface (UART) and one I/O line. The measurement is started when a short high-level
impulse is send out to the Heart rate module on the P0.0 line. This is performed each time SW2 is pressed. The
measurement is active when the green LEDs on the HRM module are flickering.

The measurement is done as long as the finger is placed upon the sensor. It is stopped a while after removing the finger.
The measurement values are transmitted via UART interface the BLE module. The communication protocol is
described in detail in R013338EJ0120. Figure 5 shows the interconnection between Heart rate module and Bluetooth
module.
The BLE interface is handled by the module r_hrm_app_ble.c. The sensor values are transferred to the BLE API each
second.
4.1.3
Pedometer
The pedometer utilizes the acceleration part of the digital 9-axis sensor BMX055 from Bosch Sensortec. The
pedometer.c module calculates steps, distance and cadence. Accel.c is the high-level driver of the sensor chip.
The BLE interface is handled by the module r_rscp_app_ble.c. The sensor values are transferred to the BLE API each
second. In addition to that the total number of steps is also transferred in the data array of the custom profile.

(7) Battery charging is completed when battery voltage reaches charge control voltage and charging current
reaches charge complete current set by “Option” / “RX setting” on control tool. LED1 of the TX board is
switched over from lighting up to turning off the lights.
(8) The “Driver ON” in TX side window can’t stop bridge circuit in ATPC Mode. When SW3 of TX board is
pushed, TxIC become standby and TxIC register is initialized. Therefore bridge outputs stop. When SW3 of
TX board is released, TxIC is activated. When TxIC is activated, TxIC register isn’t set. If you want to operate
bridge circuit again, click the “TX ON” and close the TX side window. Then click the “TX ON” again, open
the TX side window. Because TxIC register is set by this manipulation, bridge circuit operates again when the

General Precautions in the Handling of Microprocessing Unit and Microcontroller Unit Products
The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from Renesas.
For detailed usage notes on the products covered by this document, refer to the relevant sections of the document as
well as any technical updates that have been issued for the products.
1. Handling of Unused Pins
Handle unused pins in accordance with the directions given under Handling of Unused Pins in the
manual.
 The input pins of CMOS products are generally in the high-impedance state. In operation with
an unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of
LSI, an associated shoot-through current flows internally, and malfunctions occur due to the
false recognition of the pin state as an input signal become possible. Unused pins should be
handled as described under Handling of Unused Pins in the manual.
2. Processing at Power-on
The state of the product is undefined at the moment when power is supplied.
 The states of internal circuits in the LSI are indeterminate and the states of register settings and
pins are undefined at the moment when power is supplied.
In a finished product where the reset signal is applied to the external reset pin, the states of
pins are not guaranteed from the moment when power is supplied until the reset process is
completed.
In a similar way, the states of pins in a product that is reset by an on-chip power-on reset
function are not guaranteed from the moment when power is supplied until the power reaches
the level at which resetting has been specified.
3. Prohibition of Access to Reserved Addresses
Access to reserved addresses is prohibited.
 The reserved addresses are provided for the possible future expansion of functions. Do not
access these addresses; the correct operation of LSI is not guaranteed if they are accessed.
4. Clock Signals
After applying a reset, only release the reset line after the operating clock signal has become
stable. When switching the clock signal during program execution, wait until the target clock signal
has stabilized.
 When the clock signal is generated with an external resonator (or from an external oscillator)
during a reset, ensure that the reset line is only released after full stabilization of the clock
signal. Moreover, when switching to a clock signal produced with an external resonator (or by
an external oscillator) while program execution is in progress, wait until the target clock signal is
stable.
5. Differences between Products
Before changing from one product to another, i.e. to a product with a different part number, confirm
that the change will not lead to problems.
 The characteristics of Microprocessing unit or Microcontroller unit products in the same group
but having a different part number may differ in terms of the internal memory capacity, layout
pattern, and other factors, which can affect the ranges of electrical characteristics, such as
characteristic values, operating margins, immunity to noise, and amount of radiated noise.
When changing to a product with a different part number, implement a system-evaluation test
for the given product.
