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.
