// Icon images are stored in tabs ^ e.g. Alert.h etc above this line
// more than one icon can be in a header file

// Arrays containing FLASH images can be created with UTFT library tool:
// (libraries\UTFT\Tools\ImageConverter565.exe)
// Convert to .c format then copy into a new tab

/*
 This sketch demonstrates loading images from arrays stored in program (FLASH) memory.

 Works with TFT_eSPI library here:
 https://github.com/Bodmer/TFT_eSPI

 This sketch does not use/need any fonts at all...

 Code derived from ILI9341_due library example

 Make sure all the display driver and pin connections are correct by
 editing the User_Setup.h file in the TFT_eSPI library folder.
