The above tutorial is for PIC 16F877A, you might need to make some changes to work with PIC 18F14K22. My linear regulator is too weak. This directory may contain more than one code example. The first half of this tutorial will explain what the UART is, while the second half will give you instructions on how to add UART functionality to your $50 robot. PIC pin 15 (also RP15) is the UART transmitter, we put the UART transmitter PPS number (U1TX_O) in the RP15 PPS register. 55 and xc16 compiler. We Love Electricity. I've cut it down to a bare minimum to avoid too much confusion from irrelevant stuff! 1) To allow changes to the PPS you need to explicitly allow this either in runtime with a special unlock sequence, or just by turning off the IOL1WAY config bit. I suggest you add code for checking the OERR and FERR UART flags and reset the UART per Microchip's instructions if one of them is set. Read about 'Microchip: Selection Guide for PIC24 Microcontroller Family' on element14. it seems like the while loop that looks at IFG2 & UCA0TXIFX is where my problem seems to occur.
