Attempting to Alter the Duty Cycle w/o changing any other values

[AKLitman]

Arduino IDE 1.8.19
RP2040_PWM - v1.0.4
Using Example - PWM_DynamicFreq

I'd like to modify the Duty Cycle w/o altering the Frequency. My goal is to change the speed of a DC Motor
in a small project. When I change the Duty Cycle in the example without changing the frequency, the Duty Cycle
remains the same as it was before the "SetPWM" call. I looked at your code to see if I was using the wrong call
but do not see a specific call for altering only the Duty Cycle. If I alter the Frequency in your example by any
amount, the Duty Cycle is changed as I specify in the SetPWM call. If I do not alter the Frequency, the Duty Cycle
remains unchanged.

Can you show me the proper way to alter the Duty Cycle w/o changing any other values?

Hi @AKLitman

Thanks for opening the issue which I can consider as a real bug or an enhancement request.

I'll fix and create a new release soon to let you alter the DC on-the-fly.

Hi @AKLitman

The new RP2040_PWM releases v1.0.5 has just been published. Your contribution is noted in Contributions and Thanks

Please try the new example PWM_DynamicDutyCycle which demonstrates how to change dutyCycle and keep same frequency on-the-fly.

Best Regards,

Releases v1.0.5

1. Permit changing dutyCycle and keep same frequency on-the-fly. Check Attempting to Alter the Duty Cycle w/o changing any other values #3
2. Add example PWM_DynamicDutyCycle to demonstrate new feature
3. Add support for more boards using arduino-pico core, such as ADAFRUIT_ITSYBITSY_RP2040, CYTRON_MAKER_NANO_RP2040, SPARKFUN_PROMICRO_RP2040, CHALLENGER_2040_WIFI_RP2040, ILABS_2040_RPICO32_RP2040, MELOPERO_SHAKE_RP2040, SOLDERPARTY_RP2040_STAMP, UPESY_RP2040_DEVKIT, WIZNET_5100S_EVB_PICO, etc.
4. Display compiler informational warning messages only when _PWM_LOGLEVEL_ > 3

Thank you. I will download and try this out. Your code is very straightforward and I found the library easy to install and use. This new feature will greatly enhance its use for speed control on the Cytron Maker Pi board. Austin

UPDATE: The new Feature works perfectly. My Cytron Maker Pi board responds exactly as intended now. Many thanks for being very responsive and accommodating. Austin
