 * FX basic example v1.02 by Mr.Blinky    May 2021 - Feb 2022 licenced under CC0
 * *****************************************************************************
 * 
 * This is a basic example that shows how you can draw a image from FX external
 * flash memory. It will draw the Arduboy FX logo and move it around the screen.
 * 
* Before this example sketch is uploaded and run on the Arduboy FX, make sure 
 * the fxdata this sketch has been build and uploaded to the Arduboy FX. 
 * 
 * If the Arduboy FX Arduino plugin has been installed you can simply choose the 
 * 'Build and upload Arduboy FX data' from the Arduino IDE Tools menu.
 * 
 * Alternatively the fxdata.txt script file can be build using the fxdata-build.py 
 * Phyton script and the fxdata.bin file can be uploaded using the uploader-gui.py, 
 * fxdata-upload.py or flash-writer.py Python script using the -d switch.
