Overview
The Renesas RA4M1 group of micrcontrollers (MCUs) uses the high-performance Arm® Cortex®-M4 core and offers a segment LCD controller and a capacitive touch sensing unit input for intensive HMI designs. The RA4M1 MCU is built on a highly efficient low power process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA4M1 is suitable for applications where a large amount of capacitive touch channels and a segment LCD controller are required.

This sample software acquires gas data from the ZMOD4410 and ZMOD4510 gas sensors and calculates
the result. In combination with the I2C driver of the FSP, the sample software controls the ZMOD4410 and
ZMOD4510 through the I2C in the MCU to measure gases, acquire ADC data, and calculate the acquired
result. Related Files: ZMOD4xxx Sample applicationCompiler: GCC IDE: e2 studio |
