* PROGMEM Image Viewer
|
|
* This is a simple PROGMEM bitmap image viewer example
|
|
* Image Source: https://support.arduino.cc/hc/en-us/articles/360020652100
|
|
*
|
|
* How to create custom image:
|
|
* 1. Open image in the GIMP
|
|
* 2. Resize image to fit for the display and MCU memory
|
|
* 3. Export Image as C-Source
|
|
* 4. Uncheck all option and check "Save as RGB565 (16-bit)"
|
|
* 5. Revise exported file just like "Arduino_UNO_Rev3_Ok.c"
