Believe it or not I am running out of GPIO pins even with the Tindie breakout board. To save pins I would like to use I2C to talk to external devices, but I note that the Audio board has the SDA and SCL pins active for its own use. The question is can I use the standard I2C bus at the same time, without enabling the alternate pins? I guess another way to ask is: how busy is the standard bus while the Audio board is active? I seem to remember reading somewhere that it is only used for passing parameters... My use would be only sporadic - maybe 20 bytes/second at most.
Thanks,
Derek
