Using -D WLED_ENABLE_DMX when audio is included result in compile failure

[dosipod]

What happened?

When compiling -D WLED_ENABLE_DMX and the audio usermod is also included ( it is there by default now ) you would get the error

Compile is fine if the audio usermod is disabled I have no dmx fixture to verify functionally afterword but just helping someone with the compile so not sure that is expected or not

To Reproduce Bug

Use -D WLED_ENABLE_DMX on 15.0-b7

Expected Behavior

No failure

Install Method

Self-Compiled

What version of WLED?

0.15.0-b7 (build 2410270)

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

No response

Anything else?

@dosipod thanks, interesting find

This message was actually not added by me 🤔

@blazoncek do you remember why you've added this error? Does DMX output require I2S ?

[blazoncek]

I no longer remember why, but it was definitely intentional. As DMX is not a default feature I would assume that the person compiling would understand the message and remove audioreactive usremod from compilation. This is true for some other compile settings as well.

[dosipod]

netmindz mentioned that when using dmx that the unit might be not used for anything else even led output ( I see the unit crashes when i use led output ) so might be the case its dmx only unit

[netmindz]

DMX output is just serial output so I don't think it's a conflict but perhaps more an issue of lack of CPU time

[dosipod]

I went back to v0.14.4 to compare and the audio usermod seems to be working fine with dmx out enabled and I do not see any issue when enabling led output so must be a reason for the change on 15.0-b7

[dosipod]

The behavior we see is as follows ( before we try softhack fix ) :

A) On 14.4 with dmx out enabled and AR included : A.1) Enabling AR does not seem to cause any issue at least for audio sync . A.2) Setup of led output also works fine with dmx out (Proxy Universe set to 0 then fps is very low) and (Proxy Universe set to 1 then fps is normal ) ,we can change Proxy Universe back and forth without any issue

B) On 15.0-b7 with dmx out enabled and AR disabled : If you setup led output and try to change Proxy Universe from 1 to 0 then you will see a crash ( not enabled debug yet to keep changes to minimum )

[dosipod]

@softhack007 I can still see the crash now even after the fix by just setting led output with 256 leds with dmx enabled build . So seems the whole dmx is busted but I am going to leave this be as I have no fixture nor a real interest in DMX but still if you need us to test the crash part then that we could do

[blazoncek]

@dosipod please use exception decoder when posting crash dumps. Without it they are almost meaningless. The only usable information from this crash dump is that it is caused by invalid pointer.

[dosipod]

@blazoncek When I enabled debug there was nothing useful , might be you could give that a shot
