Description

This embedded application source code illustrates how to implement a HID mouse application over the AT90USBxxx controller.

About the sample application

The sample code is delivered for STK526.

Architecture

As illustrated in the figure bellow, the application entry point is located is the main.c file. The main function first performs the initialization of a scheduler module and then runs it in an infinite loop. The scheduler is a simple infinite loop calling all its tasks defined in the conf_scheduler.h file. No real time schedule is performed, when a task ends, the scheduler calls the next task defined in the configuration file (conf_scheduler.h).

The sample dual role application is based on two different tasks:

• The usb_task (usb_task.c associated source file), is the task performing the USB low level enumeration process in device mode.
• The mouse task performs mouse events decoding and report construction to the USB host.
