Overview

This example can work with a USB HID keyboard. When connecting a USB HID keyboard and pressing keys, the serial port will output which key has been pressed.

SDK version

  • Version: 2.15.000

Toolchain supported

  • IAR embedded Workbench 9.40.1
  • Keil MDK 5.38.1
  • GCC ARM Embedded 12.2
  • MCUXpresso 11.8.0

Hardware requirements

  • Two Micro USB cables
  • One USB A Female to Micro B Male cable
  • One USB keyboard
  • Target Board
  • Personal Computer(PC)

Board settings

This example can work with the USB high speed port (P9) or the USB full speed port (P10). High speed: Install jumper in position 1-2 pins of J6 and open J7 jumper. Full speed: Install jumper in position 2-3 pins of J6 and short J7 pins.

Prepare the Demo

  1. High speed: Connect the USB A Female to Micro B Male cable between the USB keyboard and the on-board USB high speed port (P9). Full speed: Connect the USB A Female to Micro B Male cable between the USB keyboard and the on-board USB full speed port (P10).
  2. Connect a USB Micro cable between the host PC and the Debug Link USB port (P6) on the target board.
  3. Connect a USB Micro cable between the PC and the on-board USB power port (P5).
  4. Open a serial terminal on the PC with the following settings:
    • 115200 baud rate
    • 8 data bits
    • No parity
    • One stop bit
    • No flow control
  5. Compile the demo:
    • High speed: Set USB_HOST_CONFIG_IP3516HS to 1 in board_setup.c
    • Full speed: Set USB_HOST_CONFIG_IP3516HS to 0 in board_setup.c
  6. Download the program to the target board.
  7. Press the on-board RESET button to start the demo.

Running the demo

After writing the program to the flash of the target board, press the reset button on your board to start the demo. The serial port will output:
