Hello, I am trying to connect my dsPIC33FJ64GP802 to my PC over RS232 and I'm having difficultly getting it set up. This chip operates on 3.3v, so I am running the TX pin to an opamp to bump it up to 5v, and then running that to the MAX232. I've verified that 0v input gives me +8.5v out and...
pin 2: +8.4v
pin 6: -8.1v
Thanks again for the help!
