ASF USB host and device HID mouse

Human interface on EVK1100 :

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.

• PWR led is on when power present
• Led 0 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 2 blinks when USB host has checked and enabled HID mouse interface
  • Mouse buttons are linked to switch PB0 (left), PB1 (middle), PB2 (right)
  • Joystick are used to move mouse
  • Only Push joystick button can be used to wakeup USB Host in remote wakeup mode.
• host mode:
  • Led 1 is on when Vbus is present
  • Led 2 is on when a device is connected
  • Led 3 blinks when the device is enumerated and USB in idle mode
  • Led 4 green is on when the mouse left button is down
  • Led 4 red is on when the mouse right button is down
  • Led 5 green is on when the mouse move
  • Switch PB0 allows to enter the device in suspend mode
  • Switch PB1 allows to enter the device in suspend mode with remote wakeup feature authorized
  • Only Push joystick button can be used to wakeup the USB devices in suspend mode

Note: On board the LED labels are incremented of one. E.g. Led0 in software corresponding at Led1 label on board.

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)
