ViSi-Genie Magic File Size Request Arduino

Name : 4D-AN-00166
Title : ViSi-Genie Magic File Size Request Arduino
Revision : 1.0
Description :

This application note shows how to write a sketch for an Arduino program that sends WRITE_MAGIC_BYTES messages to and handles REPORT_MAGIC_EVENT_BYTES messages coming from the display module.

Using the above messages, the Arduino program performs a file size request operation, a file append operation, and then another file size request operation. This sequence was used to show that the file size request operation is indeed functioning. To understand the file append part of the operation, the reader is advised to refer to the application notes

ViSi-Genie Magic How to Append to a File Arduino.

This application note will focus only on the file size request aspect of the operation.
