i have been troubleshooting for the past two days but none of the fixes work.. i tried making different connections, checked the connections for continuity, different versions of tft_espi library, different spi frequencies, changing 3v3 to 5v etc. but none of these worked.. i tried running TFT_ReadWrite_Test with the above setup file and this is the output: image my connections: connections.zip

i went through all of the ILI9341 issues on the issues page and tried almost all of the troubleshooting steps.. none works.. i highly doubt if there is any compatibility problems with either the board or display since i've seen people say they changed their board/display and everything started working...

any help is highly appreciated.. thanks in advance :)

The vendors page states Spfd5408 controller, so it is not an ILI9341 display.

The Spfd5408 controller is not supported by TFR_eSPI.
