LVGL port to be used with epaper displays

cale · May 30, 2021, 8:26pm

Hello @kisvegabor
The drawPixel draws the pixel in the buffer only. With update is finally sending to the display, but many thanks for your reply.
Is now working better I just needed to add more buffer memory. I will look into @zapta answer maybe that’s a way to improve speed considerably.

Updated my fork to add Lilygo EPD47 touch controller that is L58 similar to FocalTech existing ones but with an INT pin ( low on event )

Driver updated with partial update:

github.com

martinberlin/lvgl_epaper_drivers/blob/master/lvgl_tft/epdiy_epaper.cpp

#include "esp_log.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"

#include "epdiy_epaper.h"

// NOTE: This needs Epdiy component https://github.com/vroland/epdiy
// Run idf.py menuconfig-> Component Config -> E-Paper driver and select:
// Display type: LILIGO 4.7 ED047TC1
// Board: LILIGO T5-4.7 Epaper
// In the same section Component Config -> ESP32 Specifics -> Enable PSRAM
#include "parallel/ED047TC1.h"
Ed047TC1 display;
