# TinyUSB Composite Device (MSC + Serial) Example
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
A USB device can provide multiple functions that are active simultaneously. Such multi-function devices are also known as composite devices. This example shows how to set up ESP chip to work as a USB Serial Device as well as MSC device (Storage media as SPI-Flash).
|
||||
|
||||
As a USB stack, a TinyUSB component is used.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
Any ESP board that supports the USB-OTG peripheral.
|
||||
|
||||
### Pin Assignment
|
||||
|
||||
_Note:_ In case your board doesn't have micro-USB connector connected to USB-OTG peripheral, you may have to DIY a cable and connect **D+** and **D-** to the pins listed below.
|
||||
|
||||
See common pin assignments for USB Device examples from [upper level](../../README.md#common-pin-assignments).
|
||||
|
||||
Next, for Self-Powered Devices with VBUS monitoring, user must set ``self_powered`` to ``true`` and ``vbus_monitor_io`` to GPIO number (``VBUS_MONITORING_GPIO_NUM``) that will be used for VBUS monitoring.
|
||||
|
||||
### Build and Flash
|
||||
|
||||
Build the project and flash it to the 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.
|
||||
|
||||
## Example Output
|
||||
|
||||
After the flashing you should see the output at idf monitor:
|
||||
|
||||
```

||||
