RAA457100 RY7011RL78/G1DI/OHeart Rate ModuleRL78/I1EI²CUARTI/OSensors Figure 3 RX Board Block Diagram 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.
Charge-It Solution Kit User Manual Software R19US0003ED0101 Rev. 1.01 Page 6 of 39 Dec. 15th, 2017 3. User manual 3.1 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.
Charge-It Solution Kit User Manual Software R19US0003ED0101 Rev. 1.01 Page 7 of 39 Dec. 15th, 2017 4. Implementation Details This section describes the implementation details of the RL78/G1D firmware that is running the BLE module RY7011. 4.1 Software Architecture Figure 4 shows the software architecture of the application. RL78/G1Dr_ble_appr_hrm_app_commUART rBLE Protocol StackI²C DriverSensor driver ssensorsaccelpedometerRF / BBr_scp_app_bler_rscp_app_bler_htp_app_bler_hrm_app_bleADCr_chg_app Figure 4: Software architecture 4.1.1 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.
Charge-It Solution Kit User Manual Software R19US0003ED0101 Rev. 1.01 Page 8 of 39 Dec. 15th, 2017 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. RY7011RL78/G1DHeart Rate ModuleI/OUA RTP0.0RXD 1SW2 Figure 5: Hear Rate Monitor Module 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.
Charge-It Solution Kit User Manual Software R19US0003ED0101 Rev. 1.01 Page 9 of 39 Dec. 15th, 2017 4.1.4 Health Thermometer The health thermometer BLE service transmits the temperature values of the infrared thermopile sensor TMP007 from Texas Instruments. The temperature values are retrieved within the sensors_handler() routine in sensors.c. The BLE interface is handled by the module r_htp_app_ble.c. The sensor values are transferred to the BLE API each second. 4.1.5 Charging Monitor The charging monitor is implemented in module r_chg_app.c. It has two parts. The first is the monitoring of the status lines of the wireless charging RX chip. The second part is the battery voltage measurements. This one is implemented using a 1:1 voltage divider and an ADC input of the RL78/G1D. RL78/G1DP2.0ADCRAA457100RX_BUZRX_MODERX_CHGINTP1.3P3.0P13.7 Figure 6: Charging Monitor The monitoring of the status lines of the RX is done by the function ChrgApp_GetState(). The states are stored and transmitted in a single status byte. Figure 6 depicts the elements of the charging monitor and their wiring. The voltage measurement and charging state monitoring are triggered from sensors_handler() in sensors.c. The data is transferred to the BLE API each second using the custom profile in r_scp_app_ble.c. For further details please read chapter 4.3.5.

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.
