43.9. TINYUSB HOST CDC MSC HID FREERTOS

43.9.1. Overview

This example project shows USB CDC MSC HID HOST

43.9.2. Board Setting

  • Connect a USB port on PC to the PWR DEBUG port on the development board with a USB Type-C cable

  • Connect a USB port on the development board USB0 to cdc, hid or msc device with a USB Type-C convert Type-A cable

43.9.3. Running the example

  • Download the program to the development board to run, and use the serial port debugging assistant to view the output log

43.9.3.1. Connected with a keyboard

  • When the USB port0 of the development board is connected with a keyboard, the serial port debugging assistant will display the following data:

TinyUSB Host CDC MSC HID Example
HID device address = 1, instance = 0 is mounted
HID Interface Protocol = Keyboard
HID device address = 1, instance = 1 is mounted
HID Interface Protocol = None
HID has 2 reports

  • When the keyboard is pressed, the data sent by the keyboard will be displayed, for example, input “hpmicro”:

hpmicro

43.9.3.2. Connected with a mouse

  • When the USB port0 of the development board is connected with a mouse, the serial port debugging assistant will display the following data:

TinyUSB Host CDC MSC HID Example
HID device address = 1, instance = 0 is mounted
HID Interface Protocol = Mouse

  • When moving or clicking the mouse, the data sent by the mouse will be displayed:

(-25 -68 0)
(-18 -44 0)
(-12 -27 0)
(-7 -16 0)
(-1 -1 0)
(1 -2 0)
(5 -5 0)

43.9.3.3. Connected with a U disk

  • When the USB port0 of the development board is connected with a U disk, the serial port debugging assistant will display the U disk information data:

TinyUSB Host CDC MSC HID Example
A MassStorage device is mounted
A device with address 1 is mounted
IS917    innostor rev 1.00
Disk Size: 7500 MB
Block Count = 15360000, Block Size: 512

43.9.3.4. Connected with a CDC-ACM device

  • When the USB port0 of the development board is connected with a CDC-ACM device, the serial port debugging assistant will display the following data:

TinyUSB Host CDC MSC HID Example
CDC Interface is mounted: address = 1, itf_num = 0
  Baudrate: 115200, Stop Bits : 0
  Parity  : 0, Data Width: 8

  • When you type any characters in the console, the CDC device will forward them to the Host, and the Host’s console will echo them back.
