// 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);
