// This sketch draws BMP images pulled from SPIFFS onto the TFT. It is an
// an example from this library: https://github.com/Bodmer/TFT_eSPI

// Images in SPIFFS must be put in the root folder (top level) to be found
// Use the SPIFFS library example to verify SPIFFS works!

// The example image used to test this sketch can be found in the sketch
// Data folder, press Ctrl+K to see this folder. Use the IDE "Tools" menu
// option to upload the sketches data folder to the SPIFFS

// This sketch has been tested on the ESP32 and ESP8266
