im working on running an i2c 4x20 lcd + numeric keypad controller on my tricolour mendel. the first hurdle is that the slave melzi uses the i2c scl signal as a clock. ive looked at the marlin master and slave firmware and it looks like i can move the slave clock to ext-a1. has anyone done this?
here is the lcd + keypad i'll hopefully be using - [
