Brian:
Your loop logic seems a bit odd to me. It may work OK but wouldn't it kind of make more sense to do this: Initialize Timers and UART (including clear of RI and TI) LOOP: Poll for RI Grab byte from SBUFINP Clear RI Poll for TI being set Clear TI Stuff byte to SBUFOUT Go back to LOOP Michael Karas |
