the code is suposed to replicate the recived byte Are you sure your hardware is OK? To test the hardware, you can perform a simple loop-back test. Power off your circuit, pull out the micro, short the TX and RX on the micro socket and power it up again. Now send some characers from PC at whatever baudrate, you should receive them back if your hardware is working fine (turn off echo on your terminal software). |
