Bitmap cannot be found from SD card (ILI9341 TFT and Arduino

by LlamaLeader on Sun Mar 08, 2020 8:48 pm

I am using the code from https://learn.adafruit.com/adafruit-2-8 ... ng-bitmaps to test loading bitmaps onto my ILI9341 TFT screen using my Arduino Mega 2560 but every time I run the sketch the serial monitor says Loading purple.bmp to screen...File not found. even though the bitmap image is on the SD card. The SD card is detected by the code but the file just will not be read. Has anyone else ran into this problem and been able to fix it? Or if there is a different library that I should use I'm open to any suggestions.

Try running the SD card info example from the SD library which dumps the contents of the SD card. Does the purple.bmp file show up OK in that output?
