Hi thank you for the spot.
I have edited my post.

Hello,
I need to deliver a sample PCBA and firmware to my customer Thursday morning so I need to be able to change the frequency ASAP
thx

Sorry for the delay.
Hopefully should work for you now. Note you need to set the frequency after the PWM output is enabled otherwise the enable function will default back to the frequency set in the component properties.

thx Ben , I will test it now

hi Ben,
The PWM component you modified is PWM (CAL) isn't ?

Hello.
No, it is the PWM (internal) component, and the digital simulation had also got broken, so that has now been fixed.

ok
but when I check for update, the component new version is cal_pwm.

and what is duty cycle range now for ESP32 ?
Set frequency do not work on FC PWM (internal) component.
Please also check duty cycle because I need to setdutycycle10bit to 32 to get 50% duty cycle .
What must be the max value for period overflow ?
32 is very low!
The modification you made are also for ESP32 Wroom ?

Hello,
The PWM period property can be set up to 65535 on the ESP32, The duty can be between 0 (full off) and the period (full on).

hello Ben,
I want to use 8 PWM output, the frequencies and dutycycle could be differents.
On the print screen below only 4 are setup for the moment.
Channel used are 1 to 4
On PWM component it's wrote that all PWM linked to the same timer will share same periode and prescaler .

I have set all period overflow to 65535. ok for me
so the prescalers will be same
The problem is that when I change the frequency:
- on PWM:0 timer:0 pin:A, , the frequency also change on PWM:0 timer:0 pin:B
- on PWM:0 timer:1 pin:A, , the frequency also change on PWM:0 timer:1 pin:B
