Description of Change

This pull request improves the behavior ofanalogWriteFrequency andanalogWriteResolution functions in theesp32-hal-ledc.c file. The changes ensure that when a pin is not yet attached to the LEDC bus, frequency and resolution updates are applied to the global settings that are later used when callinganalogWrite.

Improvements to pin-specific configuration:

UpdatedanalogWriteFrequency to check if the pin is attached to the LEDC bus and apply the frequency change to the pin, falling back to updating the global frequency if not attached.
UpdatedanalogWriteResolution to check if the pin is attached to the LEDC bus and apply the resolution change to the pin, falling back to updating the global resolution if not attached.

Test Scenarios

Tested using simple sketch on ESP32.

voidsetup() {analogWriteFrequency(5,1000);analogWriteResolution(5,10);analogWrite(5,1000);}voidloop() {// put your main code here, to run repeatedly:}

Pull Request Overview

This PR fixes the behavior ofanalogWriteFrequency andanalogWriteResolution functions to allow setting frequency and resolution parameters before callinganalogWrite. Previously, these functions would fail if called before the pin was attached to the LEDC bus.

Added pin attachment checks to both functions before attempting to change pin-specific settings
Functions now fall back to updating global settings when pin is not yet attached
Eliminates error messages when configuring frequency/resolution before analogWrite
