Hello@powersoft

lv_conf.h

M5Stack was modified and Super M5Stack was produced.
The speed of Super M5Stack achieves 5.3 times his M5Stack !

New CH552 firmware for Short-Wifi-Issue of M5Atom/Stick/TimerCAM/etc. : About 9 months ago

Hello @RolfF

It's a design mistake.
It is a basic mistake to add 5V to 3.3V system.
5V enters the RF circuit, causing deterioration or damage.
There are many cases where ATOM has already broken.

Hi! @teastain
I'm sorry.
I didn't understand the question.
Therefore, the post has been deleted.

Hello@F3l1x

In the example below I am using lcd-image-converter.
