Renesas OB1203 Sensor Control Module Firmware Integration Technology
Introduction
This application note explains the sensor control module for Renesas sensor OB1203 (Renesas heart rate,
blood oxygen concentration, pulse oximetry, proximity, light and color sensor) using Firmware Integration
Technology (FIT).
These control modules acquire the sensor data using the I2C bus control FIT module (IIC FIT Module). And
calculate light/proximity/PPG value.
Hereinafter, the modules described in this application note is abbreviated as following,
- The sensor control module for OB1203: OB1203 FIT module
The detail descriptions include “Overview”, “API Information” and “OB1203 API Functions” of this FIT module
are described in application note “Renesas Sensor Control Modules Firmware Integration Technology
(R01AN5892)”.
Please refer to “Renesas Sensor Control Modules Firmware Integration Technology (R01AN5892)” for using
this FIT module.
Target Device
• Sensors:
Renesas Electronics OB1203 Heart Rate, Blood Oxygen Concentration, Pulse Oximetry,
Proximity, Light and Color Sensor (OB1203 sensor)
• RX Family MCUs:
MCUs supported the following IIC FIT module
I2C Bus Interface (RIIC) Module (RIIC FIT Module)
Simple I2C Module (SCI_IIC FIT Module) using Serial Communication Interface (SCI)
• Operation confirmed MCU:
