Hi,
why i need c/c++?? it is because i wan using 8051 to generate a pwm signal for controlling various servo motor to a different position at same time.. I using c/c++ to process my data in pc first, then i wish to send the data to 8051( through serial port, or I/O port), to let 8051 generate a signal for me, and then send it to the motor..

I am new to 8051, and i couldnt give up, coz this is part of my postgraduate project :p

Thanks!!!!
