|
|
* FX Hello world example v1.00 by Mr.Blinky Mar.2022 licenced under CC0
|
||
|
|
* *****************************************************************************
|
||
|
|
*
|
||
|
|
* This is a example that shows how you can draw texts from the FX flash chip.
|
||
|
|
* It will draw some text, number, and a scrolling message using different
|
||
|
|
* fonts and drawing modes.
|
||
|
|
*
|
||
|
|
* Before this example sketch is uploaded and run on the Arduboy FX, make sure
|
||
|
|
* the fxdata of 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.
