I2C communication between PSoCs
I'm having a problem using I2C to communicate between two PSoC4's.
I've tried several example project to narrow down what's wrong, but none of them seem to be working. I've tried using a master project that I've previously used with a LM75 temperature sensor, but that didn't work with a PSoC slave.
I've tried simply using the I2CMasterSendStart() method, which returned succesful, but then I2CMasterWriteByte() returned the error "master lost arbitration".
I've include the projects I've been testing.
