# USB CDC-ACM Virtual Com Port example

(See the README.md file in the upper level 'examples' directory for more information about examples.)

This example shows how to extend CDC-ACM driver for Virtual Communication Port devices,
such as CP210x or FTDI FT23x devices.

## How to use example

1. Pick your USB-to-UART device by executing `idf.py menuconfig` and navigating to `Example Configuration -> USB-to-UART device type`
2. Change baudrate and other line coding parameters in `cdc_acm_vcp.cpp` to match your needs
3. Now you can use the CDC-ACM to API to control the device and send data. Data are received in `handle_rx` callback
4. Try disconnecting and then reconnecting of the USB device to experiment with USB hotplugging

### Hardware Required

* ESP board with USB-OTG supported
* Silicon Labs CP210x or FTDI FT23x USB to UART converter

Connect USB_D+, USB_D-, GND and +5V signals of your ESP chip to matching signals on USB to UART converter.

#### Pin Assignment

See common pin assignments for USB Device examples from [upper level](../../../README.md#common-pin-assignments).

### Build and Flash

Build this project and flash it to the USB host board, then run monitor tool to view serial output:

```bash
idf.py -p PORT flash monitor
```

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type ``Ctrl-]``.)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
