Hi There,
I have this cheap prototyping board that I brought from Temu, It features an inbuilt screen and an ESP8266MOD chip soldered onto some driver board. I figured out how everything was wired up (due to the lack of documentation this took a while) and I can print stuff on the display. However straight after the display is written to, it turns off. On the Panelook website it says that the driver needs to be ST7789V2 even though I cannot find that library This is the link to the display. I was using the Adafruit ST7789 library.
Any help would be much appriciated, My code is as follows:
#include <Adafruit_GFX.h> // Core graphics library by Adafruit
#include <Arduino_ST7789.h> // Hardware-specific library for ST7789 (with or without CS pin)
#include <SPI.h>
#define TFT_DC 0
#define TFT_RST 2
#define TFT_CS 5
//using Hardware SPI (11, 13 on UNO; 51, 52 on MEGA; ICSP-4, ICSP-3 on DUE and etc)
//Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST); //for display without CS pin
Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST, TFT_CS); //for display with CS pin
float p = 3.1415926;
