T5 V2.3.1_2.13: Unknown E-Paper display, cannot find correct driver
vidhill opened this issue · 1 comments
I have a LILYGO® TTGO T5 V2.3.1_2.13 Inch E-Paper Screen New Driver Chip
The drivers for the e Ink display do not work,
I am using this example https://github.com/Xinyuan-LilyGO/LilyGo-T5-Epaper-Series/blob/master/examples/GxEPD_Example/GxEPD_Example.ino
I have the following line un-commented:
#define LILYGO_T5_V213
I believe it is a different E-Paper display to the one referenced
The part number appears to be WF T0213CZ16 LW
I can compile and upload,
and I can see that it is running via the serial Monitor, but the display does not update, or render anything
The sketch that was on the board did refresh, so I do not appear to have a faulty board
I have discovered that the e-paper module labeled WF T0213CZ16 LW
is in fact Good Display GDEW0213M21
I needed to include the correct library which is:
#elif defined(LILYGO_T5_V213)
// #include <GxDEPG0213BN/GxDEPG0213BN.h> // 2.13" b/w form DKE GROUP
#include <GxGDEW0213M21/GxGDEW0213M21.h>
#else
This driver is not included in the GxEPD library..
I did find the right driver in randomly included in a number of github repo, https://github.com/ltsochev-dev/esp32-weather-station/tree/main/lib/GxEPD/src/GxGDEW0213M21
For anyone in the same situation as I was,
you need to install GxEPD then copy
GxEPD/src/GxGDEW0213M21.h
GxEPD/src/GxGDEW0213M21.cpp
GxEPD/src/BitmapExamples.h
from https://github.com/ltsochev-dev/esp32-weather-station/tree/main/lib/GxEPD/src/GxGDEW0213M21 into GxEPD
in you Arduino libraries folder
