Hi guys
It may sound like a silly question, can I connect the TX and RX (of usart) within the same pic (or other MCUs), and if I send one byte out, I can received the same byte?
I have tried it, but it doesn't seem to work in my pic18f24j10. my RX is handle in interrupt.
I have only 0 out, but if I connect my RX to some random signal, I can get some data out.
