I need to have PIC to PIC communication and the program has to be in assembly using MPLAB. November 26, 2016 at 9:11 am #13199 Ligo GeorgeKeymaster You may use the following links as a reference. PIC to PIC Communication using UART PIC to PIC Communication using I2C But you can’t use UART or I2C with 16F84A as there is no hardware module in it. You can try UART with MikroC Soft UART libraries. Sorry, currently we don’t have any reference for assembly language.

You can do the circuit in Proteus and simulate it. Author Posts Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic.
