18LF46K80 USART2 flowcontrol Not working
Posted: Wed Feb 01, 2012 5:27 pm
Good day I have an existing project that I just upgraded from an 18F2680 to a 18LF46K80 for what ever reason I can not get the Flow control to work correctly.
I created a simple program that transmits data out one port to a second chip, then reads the same data coming in on the rx pin. Without flow control it works correctly with flow enabled nothing. The issue is with USART 2. I've been working with setup for years so I'm sure I have it correct. 2 questions I have: -
1) If I incorrectly crossed the flow control pin RTS to RTS and CTS to CTS could or would this damage the port pins?
and if so how can I test to confirm.
2) Looking at the selection of chip does flowcode fully support the chip?
3) Could there be some setting that not correct.
4) Can I use the selected pins I have chosen for the flow control pins.
5) Do you have any other commendations.
Thanks in advance.
