Serial: Display Images from RAW uSD Card using Arduino

Details

Number	4D-AN-00134
Difficulty	Medium
Supported Processors	GOLDELOX
Supported Environments	Serial

Description

This application note shows how to program an Arduino host so that it can control a GOLDELOX display module (acting as a slave device) and make it display images. The images are contained in a graphics file saved on a μSD card mounted on the display module. The Arduino host sends serial commands to the display module to access 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.
