I faced common issue with core grey module, made a couple of titles and was feeding formatted data from light sensor and envII module. Had to spend some time playing with delays to make it work properly but was blaming raped micropython build.

Long things short, don't try to understand it, try adding delays.

Hi guys

if you look closely you'll find that the schematics for M5Atom Matrix and M5Atom Lite are not completely the same. Apart from the RGB LEDs (25 vs 1) only the M5Atom Matrix has an MPU6886 internally which is controlled via I2C using GPIO21 and GPIO22.

However with the ATOM Stepper Motor Driver GPIO21 and GPIO22 are used for RST (Reset) and EN (Enable).

Therefore only M5Atom Lite can be used to control the ATOM Stepper Motor Driver.

Thanks
