ASF USB host and device HID mouse

Human interface on SAM3X_EK :

Introduction

This example shows how to implement a USB dual mode (device and host) HID Mouse on Atmel MCU with USB module.

Startup

In device mode, the example uses the buttons or sensors available on the board to simulate a standard mouse. After loading firmware, connect the board to the USB Host. When connected to a USB host system this application provides a mouse application in the Unix/Mac/Windows operating systems. This example uses the native HID driver for these operating systems.

In host mode, after loading firmware, connect the board to a USB device mouse.

• Led 1 is on in host mode (when USB OTG cable is pluged)
• device mode:
  • Led 1 is on when USB line is in IDLE mode, and off in SUSPEND mode
  • Led 0 blinks when USB Host have checked and enabled HID mouse interface
  • Mouse buttons are not linked.
  • The SW0 are used to move mouse on the axis X.
• host mode:
  • Led 1 is continuously on when a device is connected
  • Led 0 blinks when the device is enumerated and USB in idle mode
  • Led 1 is on when a HID mouse button is pressed
  • Led 1 is on when the mouse move
• SW0 allows to enter the device in suspend mode with remote wakeup feature authorized
• Only SW0 can be used to wakeup USB device in suspend mode

About example

The example uses the following module groups:

• Basic modules: Startup, board, clock, interrupt, power management
• USB device and host stack and HID modules:
  services/usb/
  services/usb/udc/
  services/usb/uhc/
  services/usb/class/hid/
  services/usb/class/hid/device/mouse/
  services/usb/class/hid/host/mouse/
• 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)
