#38600 - Need help on PWM using 89c51rd2
Hi

Can anyone guide me on how to generate a 3 phase waveform using the rd2 derivative? Let me re-phrase it. I wish to time the reload of the CL registers in such a way that all three CL regs are loaded in one interrupt time so that there is no sample dragging across two pwm cycles.

ie : pwm cycle 0 - sample0
pwm cycle 1 - sample1
pwm cycle 2 - sample2

Since this is the first time I am using a rd2, I wish to clarify how to get the timing such that each sample is put out at the right time. I could not find the PWM tutorial either on this site. If it is here, please let me have the url.

Thanks for your time
Jerson
