I hope the nice people on the list can help me again this time. I have to use the i2c bus 3 to control a sound amplifier (tpa6130a2). I have an evaluation board that I will connect to the pins 23 and 24 of a Tobi board. I want to make a program that changes the volume, for example.
Thanks a lot for your time, all this is very interesting but completely new to me.
