Need some guide to start the board and use it with Platformio. (Please dont link me to meshtastic as this code is not friendly and also NRF52 example has no platformio links in it, just basic Arduino IDE with missing information about the used libraries)
I could start TFT_EN and TFT_LED_EN by putting them LOW (digitalWrite(PIN, 0)
but no matter what I could not start the TFT of the board
I hope this code can provide you with some help. You can use this code to meet your requirements on Arduino.

thanks a lot, I had to define SPI1 beforehand to use this in platformio/vscode but all is running.
