Hello
I am an engineeering student, and have interest in 8051 microcontroller
and am presently trying to write a pc at keyboard interfacing program in 8051
assembly. here i am reading the keyboard and converting it to its
relevant ascii code and sending it to the uart
its almost 10 days and i am not getting results
i have made the circuit in the following way ...
PORT 1 (P1.0) - connected to kbd clock line
PORT 1 (P1.1) - connected to kbd data line
PORT 1 (P3.0/RXD) - connected to Rxd of MAX232
PORT 1 (P3.1/TXD) - connected to Txd of MAX232
and while execution i am supposed to get the relevant ascii code
for the pressed key , sent by the micro, for this i am running HYPER TERMINAL
program, but the micro is not at all sending anythig
i am including all the code to , could anyone tell me what could
be the possible problem.
