I2C code migration from PIC16F1503 to PIC16F1508
My I2C code works on PIC16F1503 in MASTER mode. I have a new design where simultaneous 4 PWM outputs and I2C communication is desired. Hence, I ported the code from the PIC16F1503 to the new controller, PIC16F1508.
The I2C pins are changing between the two controllers, other than that I can not find anything else. However, I can not get to output I2C on the new PIC16F1508. I use the internal oscillator (16MHz), in MASTER mode and 7 bit addressing.
Any ideas where else I should look at?
