ASF USB Device HID Multi-touch

Human interface on SAM4S-EK:

Introduction

This example shows how to implement a USB Device HID Multi-touch on Atmel MCU with USB module.

Startup

The example uses the buttons or sensors available on the board to simulate a standard multi-touch. After loading firmware, connect the board (EVKxx,Xplain,...) to the USB Host. When connected to a USB host system this application provides a HID multi-touch with two points application in the Windows 7 operating systems. This example uses the native HID driver for these operating systems.

• Led 0 (D2) blinks when USB host has checked and enabled HID generic interface
• Push button 0 (SW0) is used to draw line in paint application on Windows O.S
  • Run the application and connect usb to he PC first.
  • Open paint and push button 0 continuously, then two lines painted.

About example

The example uses the following module groups:

• Basic modules: Startup, board, clock, interrupt, power management
• USB Device stack and HID modules:
  services/usb/
  services/usb/udc/
  services/usb/class/hid/
  services/usb/class/hid/mtouch/
• Specific implementation:
  • main.c,
    initializes clock
    initializes interrupt
    manages UI
  • specific implementation for each target "./examples/product_board/":
    • conf_foo.h configuration of each module
    • ui.c implement of user's interface (buttons, leds)
