ASF USB host HID mouse

Human interface on EVK1100 :

Introduction

This example shows how to implement a USB host HID mouse on Atmel MCU with USB module. The application note AVR4953 provides information about this implementation.

Startup

After loading firmware, connect the board (EVKxx,Xplain,...) to a USB device mouse.

• PWR led is on when power present
• Led 0 is on when USB OTG cable is plugged
• 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 is on when the mouse left button is down
• Led 5 is on when the mouse right button is down
• Led 6 is on when the mouse move
• Led 7 is on when a bad Vbus level has been detected
• 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 USB device 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 host stack and HID modules:
  services/usb/
  services/usb/uhc/
  services/usb/class/hid/
  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)
