I am using Keil 2 to run a program (a servo driven robotic arm) for the 87C552, I downloaded an example for the PWM usage from Keil.com, in C which works grand, but the compiler does not recognise any PWM refernces in assemblly. Why is this ? Is there any way around it?
"Assembly does not use includes." Looks like that's where you're going wrong, then: you should be using some includes - specifically, the includes that tell the Assembler about the PWM registers!
