Posted on July 11, 2005 at 12:39 hi everybody,
I'm developing firmware for a ST72F324J6 (42pin sdip package) microcontroller.
I want to generate a pwm waveform with timer A and applied it to pin OCMP1_A (pin 13).
attached you'll find the C code I wrote down.
just for test purposes the duty cycle is approx 50%.
the code do not produce the expected result: no pwm appear on OCMP1_A pin.
I checked several times the few line of code i posted here but i'm not able to find the bug in them.... pehaps some missing sttings... I followed step by step what I found on the ST72F324 manual.... I think my error is naive but I can't find it!
macro I used for setting and resetting bits (_bset & _bres) are tested and functioning.
any suggestion ??
thanks a lot for your precious help
regards
