wrong WS2812FXStripSettings.stripSize

[Talumux]

I am trying to use mclightning with a matrix of 48 by 27 LEDs (=1296 LEDs). But I got a wrong pixel count information when I run the code. The UART Output shows first the correct number (1296) but later on the last digit is cut off (129):

...
Reading neoconfig file... Opened!
Config: Parsed!
{"pixel_count":1296,"rgb_order":82,"pin":14}Reading config file... Opened!
Config: Parsed!
...
then later:
...
E1.31 mode setup complete.
Read cfg: {"mode":1,"strip_mode":0,"brightness":15,"speed":255,"red":255,"green":168,"blue":13} Success!
*WM: freeing allocated params!
Saving Strip cfg: {"pixel_count":129,"rgb_order":82,"pin":14}
...

I looked through the code an insert NUMLEDS as strip size in line 260 of McLighning.ino

void initStrip(uint16_t stripSize = NUMLEDS, neoPixelType RGBOrder = WS2812FXStripSettings.RGBOrder, uint8_t pin = WS2812FXStripSettings.pin){

instead of

void initStrip(uint16_t stripSize = WS2812FXStripSettings.stripSiz, neoPixelType RGBOrder = WS2812FXStripSettings.RGBOrder, uint8_t pin = WS2812FXStripSettings.pin){

as a quick fix.
It seems to work, but I think this is not the root cause of my problem.
Does anyone know how why the pixel count information is wrong in my case?

@Talumux How did you set the number of LEDs? Using REST API?
http://YOUR_MCL_IP/pixelconf?ct=1296

[Talumux]

@toblum I edited the definitions.h and set #define NUMLEDS 1296

[toblum]

@Talumux Could you please try and set the number of LEDs using the call is posted above?

[Talumux]

Hi, I set the number of LED using the pixelconf?ct=1296 command.
After that all LEDs are working as expected. But after a reset (example power off), the wrong pixel size of 129 ist restored. The Output via Uart is (see the last line!):

(Now I used the original code without any modifications mentioned in the first post.)

Hi @Talumux,

it seems like the config file couldn't be stored. What is returned when you call:
http://<YOUR_MCL_IP>/list?dir=/

Regards
Tobias

[Talumux]

when I execute http://<YOUR_MCL_IP>/list?dir=/ I receive
[{"type":"file","name":"config.json"},{"type":"file","name":"stripstate.json"},{"type":"file","name":"neoconfig.json"}]

[toblum]

This looks OK. And what do you get when you call: http://<YOUR_MCL_IP>/neoconfig.json

[Talumux]

Hi Tobias,
the output of http://<YOUR_MCL_IP>/neoconfig.json is various. After a reset the output is
{"pixel_count":129,"rgb_order":82,"pin":14}. After executing http://YOUR_MCL_IP/pixelconf?ct=1296 the output is {"pixel_count":1296,"rgb_order":82,"pin":14}
Thanks for your ideas so far!

[Talumux]

Maybe you can have a look at the following output.
I set /pixelconf?ct=1296
I checked /list?dir=/
I checked /neoconfig.json
I did a hw reset (e.g. I opened the Arduino Serial monitor again) and get the following output

FS File: /style.css, size: 489B
FS File: /stripstate.json, size: 86B

Hi @Talumux,

I think I found the cause of the issue. The setting was truncted to three numbers, so that 1296 resulted in 129 after restart. The issue should be fixed in the next release 2.2.5.

Many greeting
Tobias

@Talumux I just published the new release: https://github.com/toblum/McLighting/releases/tag/v2.2.5
