These entries have the form B-SSSS where B is the bus number and SSSS is the I2C address of the device. It also enables. Example of common hardware definitions and configuration for all of CCS's USB example programs (ex_usb_*. I got a WICED Sense yesterday and it seems like it would fit my needs. driver driver_override firmware_node i2c-5 modalias power subsystem uevent Then, we only need to connect our I2C slave device to the right physical pins (3 and 5, as I2C1_SDA and I2C1_SCL). I configured a harmony project with these configurations attached below. One way is to connect all the sensors to I2C SCL and multiplex the I2C SDA serial line in software.
