There may be, I've usually just rolled my own routines to service the EUSART though I haven't used the '4520 specifically. I don't think there are huge differences between most EUSART enabled mid range devices so there should be plenty of example code to examine and modify for your needs. You'll need a level translator if you're going PIC to PC directly. On 14 Nov 2017 12:36, "Richard Pope" wrote: > Clint, > Yes, I am using a FTDI to RS232 converter to hook the PC to the > PIC.
