Hi! I bought this display: https://a.aliexpress.com/_mtGSvQe
It's a MH-ET Live 2.9 E-paper 4 color (b/w/r/y).
I'm using the GxEPD2 lib to use it. But i treid every combination (since for 3C and 4C), and, after run some codes, a had the _PowerOn, _UpdateFull and Power_off, but the display never changes.
I tried in the Wemos D1 Mini, Esp32 board and Arduino Mega (following the suggested connections)... and nothing :(.
If i wanst wrong, I have to use the 4C, but eh connector model not has the connector in the board:
The connector says if it is FPC-A005 20.06.15... but this connector only have to GxEPD2_BW...
Edit: It has the switch to 3 or 4 SPI lines... some "drivers" works with one and other with another...
Edit2: The ESP32 only restart with error
Anyone can help with this. I treid for 3 days and cannot use the display.
