So /dev/pmw0 = TIM1
/dev/pmw1 = TIM4
All well...... but with CONFIG_PWM_PULSECOUNT only TIM1 is working when you
give in counts.... but with counts=0 nothing happens ....
TIM4 is quitting immediatly..... with CONFIG_PWM_PULSECOUNT DISABLED I can use
both in a generic way.......
I think the:
#ifdef CONFIG_PWM_PULSECOUNT
ret = lower->ops->pulse_start(lower, &upper->info, upper);
#else
ret = lower->ops->start(lower, &upper->info);
#endif
Is too generic.... in drivers/timers/pwm.c????

Hi,
I was implementing the following use-case:
On TIM1 (advanced) timer I want to use pulse counts (By configuring and
enabling: "CONFIG_PWM_PULSECOUNT") And for TIM4 I do NOT want to use this. Just
normal time-based.
But when I use examples/pwm_main.c this is giving me very strange responses.
Also the drivers/timers/pwm.c seems to do something different then what I
expect?
Did some of you had this situation? And I do not mean "MULTICHANNEL" usage.
Thats something different and another use case.
Thanks
Ben
