hello i have problem in my project how to receive 14 bit data on the rxd pin of microcontroller?
can anybody give the source code for that.
anybody help me.....
yes 14 asynchronous bits in that 1 start 12 databits and 1 stop bits
i have to make wireless system in which i use rf module.
in tx i use encoder which generate the 1 start bit than after 8 address bit than after 4 databits than after 1 stop bit. and it sends it serially to the rf tx module.
rf recever module's receive bit is directly connect to the rxd of 89s52
"start 12 databits and 1 stop bits"
No, there is no standard 8051 hardware feature to handle that. In fact, I'm not sure that there's any standard UART at all which could handle that?
You should contact the module supplier for suggestions!
Try searching for "Software UART" or "Soft UART" - and adapt that code to the required number of bits.
"Bit-bang" would be another keyword for searching...
thanksssssssss
