16F1937 and PWM [solved]
PostPosted: Fri Aug 19, 2011 9:58 am     Reply with quote
I am having issues with the PWM on this part. I have used PWM on many other parts. I don't really care about the frequency right now just trying to get something working.

Compiler 4.124

I am setting the timer 2 setting up the CCP4 and setting the duty just like always. Is there something I am missing here?
Code:

setup_ccp4(CCP_PWM | CCP_TIMER2);
setup_timer_2(T2_DIV_BY_1, 0x33,1);
setup_comparator(NC_NC_NC_NC);
setup_oscillator(OSC_8MHZ);
enable_interrupts(GLOBAL);
set_pwm4_duty(512);

Problem solved! The CCS compliler is not setting thr TRISD bit properly in the setup_ccp4. So I have to do it manually.

Hopefully this will get fixed in an update.
