#146572 - Stop Bit Responding to: ???'s previous message |
Hi Alan,
Where would the stop bit go? The stop bit will go where the UART puts it, usually at the end. ;-) Seriously, all you need to do is initialize the proper registers to configure the UART at startup. Then when you MOV SBUF A, the bit-banging business (how's that for aliteration) is taken care of automatically. The only other thing you'll need to do is provide a level shifter (e.g. MAX 232) to translate the TTL level signals from your 8052 to the RS232 levels of ±12V. Good luck, Joe |
