Initiating 2nd I2C bus on ESP32 with CCS811 sensor ...

+

Dec 17, 2020· Initiating 2nd I2C bus on ESP32 with CCS811 sensor. I want to connect two CCS811 sensors with ESP32 dev board. Since the sensors have fixed address, I am unable to use them simultaneously. I have read that on ESP32 multiple I2C buses can be created. While trying to follow that route I tried to modify the library but I am stuck.
