Serial: Displaying Images from the uSD Card FAT16 using Arduino


Number 4D-AN-00100
Difficulty Medium
Supported Processors PICASO, DIABLO-16, PIXXI-28, PIXXI-44
Supported Environments Serial


This application note shows how an Arduino host is programmed to control a 4D display (slave device) and make it display images. The images are contained in a graphics file saved on a µSD card mounted on the µSD card slot of the display. The Arduino host sends serial commands to the 4D display slave to access the graphics file and display the images. The graphics file is of a format that is readable by 4D-LAB’s processors. This graphics file is generated using the Workshop 4 IDE.
