Overview
This example works as a USB host CDC ACM. It can communicate with a USB CDC ACM device.
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
- A USB CDC ACM device
- 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
- High speed: Connect the USB A Female to Micro B Male cable between a USB CDC ACM device and the on-board USB high speed port (P9). Full speed: Connect the USB A Female to Micro B Male cable between a USB CDC ACM device and the on-board USB full speed port (P10).
- Connect a USB Micro cable between the host PC and the Debug Link USB port (P6) on the target board.
- Connect a USB Micro cable between the PC and the on-board USB power port (P5).
- 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
- 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
- Download the program to the target board.
- Press the on-board RESET button to start the demo.
Running the demo
When the demo is running, the serial port will output:
Start the USBX HOST CDC ACM example...
Then, if connecting a device running the usbx_device_cdc_acm example to the USB device port of the board. The serial port will output:
USB device: vid=0x8484, pid=0x0 SEND: A RECV: Aabcdef
