Hi

I'm making (or trying to) a synthesizer, with touch capacitive keys.
I can get til mpr121 boards to work, using serial, or even usbmidi, and I can get the audioboard to work, with a simpel waveform synth.
But combining them i get connectionfails on the mpr121 boards some times, and other times its the audioboard that stops working.
Then I realize, that all boards are using the same i2c - is that why i'm having these problems?
Is there a way to work around it?

best regards

Kim Jensen
 
Well, I'll reply myself then... ;o)
I replaced wire.h with i2c_t3.h in all libraries regarding both the mpr121 and the audio adapter, and solders the mpr121 boards on the pins for sda1 and scl1 instead of sda0/scl0 - and it works!
 
Good work - you should post a code sample if you can make a concise repro and hardware details - Paul may be interested to understand where the wire failure was the doesn't exist in i2c_t3.
