DMX library not working with custom pins ESP-C3

[nmeurer]

What happened?

When compiling from source and redefining the hard-coded dmx output pin as mentioned in [https://kno.wled.ge/interfaces/dmx-output/](the wiki), the changed pins won't show up in WLEDs new pin overview. Also, no DMX signal is being produced. Only a constant PWM signal can be observed on the GPIO

To Reproduce Bug

• Compile WLED from source
• Enable DMX Output in wled00/wled.h
• Set the DMX Output pin to 5 in src/dependencies/dmx/ESPDMX.cpp
• Observe the GPIO with an oscilloscope
• Observe GPIO 2 still occupied by DMX in the pin overview on ESP32
• No DMX output on GPIO 2 as well

Expected Behavior

• Selected Pin 5 marked as used for DMX
• DMX signal on pin 5

Install Method

Self-Compiled

What version of WLED?

2602141 / v0.15.4 / installed via git clone https://github.com/Aircoookie/WLED.git

Which microcontroller/board are you seeing the problem on?

ESP32-C3

Relevant log/trace output

Anything else?

No response

Just FYI: for a pin to show in the pin info it must be registered through the pin manager.

Is being looked at as part of #5216

Alternatively, if you like you could also test the branch in #5522 and compile with options
-D WLED_ENABLE_DMX -D DMX_TXPIN_DEFAULT=5
Would be a charm if you reported your results there.

Would be a charm if you reported your results there.

I just compiled #5522 and confirm that it is indeed working. DMX output is there (tested with 3 channels) and pin 5 shows being used in pin overview.

This would solve both my issues I'm having
