I am trying to get my Amicus18 board to talk to a Sparkfun MPR121 Capacitive Touch Keypad over I2C. Could someone verify the maximum usable OSC value.

Right now I have it set to 64 but it looks like the PBP manual says the max usable is 20 with I2C.

Can I run it at 64 and use DEFINE I2C_SLOW 1?

Thanks John
