<![CDATA[Matrix M5.dis]]>I just purchased some M5 Atom Matrix devices and I want to start programming the LEDs. Where do I find documentation for the M5.dis API? The sample code does very little and I can't find any reference to M5.dis in the docs I've been able to find.

I'm loading M5Atom.h and FastLED.h and its just not working for me.

The M5.dis object is defined in M5Atom.h as a member of M5Atom class:

class M5Atom
{
...
    LED_DisPlay dis;
...
}
extern M5Atom M5;

For the M5Atom examples to compile I had to add M5Atom and FastLED libraries to the project. (In PlatformIO I can simply drop the two libaries into the lib directory of the project. Not sure how that works with Arduino IDE, sorry.)

led-matrix:14:10: error: 'class LED_Display' has no member named 'fillpix'

   M5.dis.fillpix(CRGB::Black);

          ^

exit status 1
'class LED_Display' has no member named 'fillpix'

I'm trying to figure out how to work with the matrix display on the Atom Matrix and I can't find any examples, end to end, that work. I found a reference to M5.dis but I'm just not seeing anything that references it or real examples of how to use it.

I tried using FastLED which is what the utility/LED_DisPlay.h code uses under the covers, even submitted some PRs today to tighten up that code, but as soon as I make any call to FastLED to update the display or show pixels, the sketch crashes.

Have you seen this? https://github.com/m5stack/M5Atom#display-api-document

I'm looking at the sample apps and I see references to M5 methods, and M5.dis but I cannot find reference documentation for them anywhere.

Where are the reference docs for the M5 SDK? What are the methods, properties, etc. for the M5.dis object?
