Does anybody have a clue how to access those other 3 modules? Regards, Michael! this is what I can see right now: test24:/media/i2c-tools # ./tools/i2cdetect 0 WARNING! This program can confuse your I2C bus, cause data loss and worse! I will probe file /dev/i2c-0. I will probe address range 0x03-0x77. Continue?
