Hi,
I am trying to get my AtomDisplay HDMI working without success.
The factory demo worked fine.
I have tried the basic example but I get nothing.
The odd thing is the display says it has 0 width and height.

Here is my code:
`
#include <Arduino.h>

#include <M5AtomDisplay.h>
M5AtomDisplay display(1280, 720, 50); // width, height

void setup(void)
{
Serial.begin(115200);

// initialize
display.init();
Serial.printf("W:%d H:%d\n", display.width(), display.height());
`
The serial output shows W:0 H:0 so it seems the display is not initialised correctly.

The same occurs when I try the default (no parameters), both are 0.

I enables logging on the ESP and the log shows the following errors so I guess this is why. Is my AtomDisplay broken or an old version that is no longer supported?
