// ILI9341 example with embedded color bitmaps in sketch.
// WILL NOT FIT ON ARDUINO UNO OR OTHER AVR BOARDS;
// uses large bitmap image stored in array!

// Options for converting images to the format used here include:
//   http://www.rinkydinkelectronics.com/t_imageconverter565.php
// or
//  GIMP (https://www.gimp.org/) as follows:
//    1. File -> Export As
//    2. In Export Image dialog, use 'C source code (*.c)' as filetype.
//    3. Press export to get the export options dialog.
//    4. Type the desired variable name into the 'prefixed name' box.
//    5. Uncheck 'GLIB types (guint8*)'
//    6. Check 'Save as RGB565 (16-bit)'
//    7. Press export to save your image.
//  Assuming 'image_name' was typed in the 'prefixed name' box of step 4,
//  you can have to include the c file, then using the image can be done with:
//    tft.drawRGBBitmap(0, 0, image_name.pixel_data, image_name.width, image_name.height);
