Frequently Asked Questions
What is an easy way for two or more PIC® MCUs to communicate?
There are two example programs (EX_PBUSM.C and EX_PBUSR.C) that show
how to use a simple one-wire interface to transfer data between PIC®
data can use pin B0 and the EXT interrupt. The built-in UART may be used for
high speed transfers. An RS232 driver chip may be used for long distance
operations. The RS485 as well as the high speed UART require 2 pins and
minor software changes. The following are some hardware configurations:
