ASF USB Device PHDC

Human interface on SAME70-Xplained:

Introduction

This example shows how to implement a USB Device PHDC on Atmel MCU with USB module. This example uses a IEEE11073 stack skeleton which has the minimum to pass USB Command Verifier 2.0 Tool (CV2.0) tests from usb.org. Note: No USB driver is provided by Atmel for PHDC, but it is not required to execute CV2.0 PHDC tests.

Startup

You must compile, load and start example. After, you can start CV2.0 and execute Chapter 9 and PHDC tests.

• Led 0 is on when USB line is in IDLE mode, and off in SUSPEND mode
• Push button 1 (SW0) are used to send a measure

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/phdc/device/
• Specific implementation:
  • main.c,
    initializes clock
    initializes interrupt
    manages UI
  • ieee11073_skeleton.c, IEEE11073 stack skeleton
  • specific implementation for each target "./examples/product_board/":
    • conf_foo.h configuration of each module
    • ui.c implement of user's interface (buttons, leds)
