New issue 188 by robhamerling: PWM parameter setting improvement
http://code.google.com/p/jallib/issues/detail?id=188
{ Reported by Thomas Ryckmans }
I have some puzzling results with PWM
if I have this:
pwm_max_resolution(1)
pwm1_on()
pwm1_set_dutycycle_highres(500)
I get a nice 8kHz square wave.
If I add
pwm_set_frequency(12_000)
I get a rectangle wave (duty about 70%) at 12KHz...
If I increase the pwm_set_frequency further, I get same 12KHz but higher
duty...
If I do
pwm_set_frequency(5_000)... I get no signal!
See the attached program
