Detailed Description

iButton Click Example.

Description

This example demonstrates the use of the iButton click boards by registering a DS1990A Serial Number iButton key and then waiting until a key is detected on the reader and identifying if the key matches one of those stored in RAM.

The demo application is composed of two sections :

Application Init

Initializes the driver and registers a new DS1990A Serial Number iButton key and stores it in RAM.

Application Task

Waits until a key is detected on the reader, and checks if there's a key found in the library that matches the one it has just read. All data is being logged on the USB UART where you can track the program flow.
