LEDDisplay example doesn't work

[misosec]

Hello, LEDDisplay example compiles without error, but led display stays blank. Is there anything specific I have to do?

Windows 10 Arduino IDE version 1.8.10 I selected M5Stick-C board.

Thank you.

I have same issue, but noticed the following compiler warning (incidentally the Easy Loader works fine):-

`C:\Users\Paul McGuinness\Documents\Arduino\libraries\FastLED/FastLED.h:14:21: note: #pragma message: FastLED version 3.003.003

pragma message "FastLED version 3.003.003"

                 ^

@PaulMcGuinness, how can I use Easy Loader to upload LEDDidplay code? There is only Burn button without option to choose a file. Or am I missing something? Thank You.

Use this one:-

@PaulMcGuinness How can I choose what to upload? Thanks again.

[PaulMcGuinness]

You can't - It just loads a pre-compiled version of the example (which should be the same as the example here on Github that doesn't work!)

[misosec]

@PaulMcGuinness I see. Thanks anyway.

change in LED_DisPlay.ccp line 103

// xSemaphoreTake(_xSemaphore, portMAX_DELAY); xSemaphoreTake(_xSemaphore, 100);

HI, I am seeing this in what I believe is the most up to date software. What was the fix?
