    Hello
    I have a slick ESP32 board with a display, from the looks of it, like a Lilygo T-Display and I can't get the display to work :( .
    The display is working, but I have deleted the supplied demo and cannot output anything to the display.
    - Display supposedly with ST7789V controller 135 x 240 resolution
    - Writing on ESP32 processor DOWD Q6, but in the software from Espressif it detects D2WD
    - I use MOSI 19, CLK 18, CS 5, DC 16, RST 23, BL 4, but BL in examples not used
    - board name at vendor "T-Display ESP32 WiFi 1.14 LCD"
    I am looking for a program that will output some lettering on this board so that there is something to follow.
    Greetings

    Hello
    Thank you in advance, I solved the problem by deleting the CPU memory with Flash_download_tool_3.9.3 and then I used the program from the page

    The program made me realise that every manufacturer is a different pin assignment, on top of that the program runs on older libraries for the ST7789V, supposedly slower, but at least it is clear how the program is supposed to work.
    Greetings
