Issue when trying to add more then 10 digital buses

[dosipod]

What happened?

The 10 buses limit is not clear , It was increased recently as I see in const.h but if you try to add more then 10 and you reboot then it will go back to 10 buses only .

The behavior before was that you can not add more then 10 digital buses as after 10 the led output will be grayed same as below

To Reproduce Bug

Add more then 10 digital buses

Expected Behavior

Exceeding the limit for digital buses should not be allowed in UI

Install Method

Self-Compiled

What version of WLED?

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?

🤔 as this (more than 10 busses on esp32) is a new feature, I think its an option to use as-is for 0.15.RC1, and fix it later.

We should then add a warning to the release notes, saying that >10 outputs are available technically, however the LED settings page has known problems with it, and it may not be possible to configure more outputs than in older versions.

Or we are lucky and someone finds a fix.

You could change the label as "needs investigation" and remove bug as I could not do that .

One thing more noticed is that this limit issue is also there when I tried to test with DDP output , in this case if you save the page with more then 10 then settings/leds will bug and all output will be gone ( strange thing is the master still control the slave even if the setting page is empty ) , rebooting does not help and factory reset might the only option as editing cfg.json might be too much effort

Debug build did not show any useful error , still the cfg.json is below when saving with more then 10 DDP output

Just FYI , I do not need 10 outputs with leds nor with DDP . I am happy with 2 and the max I have is 4 output for a unit I made only for testing . But we have received some questions from users with regard to using more then 10 outputs with DDP as they wanted that for a long time so this is not unrealistic setups if you care to check discord .

Hi, I would like to try DDP more than 10 Athom GU10 WLED bulbs, currently I have 18 bulbs split into 2 ESP32 ethernet controllers and another master controller, if I can try everything with just one controller it would be great, I would like to be able to eliminate the delay to have smooth effects like wipe and another effects;
will it be possible to add more than 10 DDP from the next version of WLED? I am very interested in adding many GU10 bulbs and I am available for all tests;
thank you!!!

@tech1977 ,As the output of more then 10 could be edge case so might be not solved ,for DDP if you need more then 10 output then we have found a simple workaround , in one of the slaves just also use DDP to other slaves , you can see details in discord here https://discord.com/channels/473448917040758787/473448917543944193/1317398474626433024 , if you do that then you can still from one master control the end slaves ( nested DDP ) with segments on the master so that is 32 segments on esp32 .

@dosipod I did this with 18 test bulbs:
bulbs from 1-10 on DDP RGBW output of the first ESP32 ethernet
bulbs from 11-18 on DDP RGBW output of the second ESP32 ethernet
third ESP32 ethernet as master with DDP RGBW output the 2 previous ESP32s for a total of 18 pixels
