is there a way to change the stop output voltage of the PWM pin I am using ( GPIO_11 ) . I am trying to create pulses at a specific frequency but the pin when stoped ( timer disable ) sets to 3.3V.. I want to be able to have to go to zero V.
I have tried changing the OC polarity to Low but that did not work .Changing the duty cycle and not stopping the PCM timer does not produce good results.
36mhz frequency and 60 percent duty cycle. I want to them use that as the carrier and pulse from 250 cycles to 2000 cycles depending on factors.
Whenever I stop the Pwm to create the low part of the pulse , the voltage goes high ( instead of low ). So I have tried then changing the duty cycle to zero to fake a Pwm stop. It's. It working well. So back to plan A and trying to find the way ( in software to have the Pwm pulse stop with a low voltage. )
