Is it possible to customise the duty cycle setting in this demo?

[canary_wharfe]

Got the PWM working in Lorlin32 Lite at my target Fq. of 1Hz.
The thing is any PWM Set Duty Cycle macro I use appears to get over-ridden by the low level settings in the component PWM. In the current code I get a duty-cycle of 50% which I can live with but would have preferred to have custom control over the duty cycle e.g. 20/80 mark / space. Is there an easy way of doing this and still retain my 1Hz PWM Fq? TIA.

Hello.
I have modified your project so PWM duty ranges from 0 to 100% when POT ranges 0 - 4095
The PWM duty is only set when the pot changes value.
If pot value is too unstable on ESP32, use the GetAverageInt function instead

Thanks Martin. That is a very elegant bit of code. Thanks also for introducing me to the maths map component. I have managed to pull out snippets of your demo and get the PWM duty cycle function working now.

You're welcome, that's great!
I'm glad I have helped you to continue your project.

Hi

Has anything happened with the ESP Lolin-Lite or PWM?

Not geting anything on a scope when I use components / properties in above post by Martin, but it does simulate.

Hi Iain .
Sorry for the delay.
I have just tested Lolin lite and PWM output is working as expected.
Attached is the project I had used.
I have included it as I have changed pins since the file attached above .

Hi Martin

Thanks.

My chart was based on the previous example and was only to enable the PWM, no need to vary Duty. I just wanted an output. It used same pins but I couldn't get anything on scope.

I'll try again based on your reply above and let you know how I get on.

Regards
