# TinyUSB Sample Descriptor
|
||||
|
||||
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||||
|
||||
This example is demonstrating how to set up ESP32-S2 chip to work as a Generic USB Device with a user-defined descriptor. You can specify a manufacturer, device's name, ID and other USB-devices parameters responsible for identification by host.
|
||||
|
||||
|
||||
As a USB stack, a TinyUSB component is used.
|
||||
|
||||
## How to use example
|
||||
|
||||
### Hardware Required
|
||||
|
||||
- Any board with the ESP32-S2 chip
|
||||
|
||||
### Configure the project
|
||||
|
||||
There are two ways to set up a descriptor - using Menuconfig tool and in-code
|
||||
|
||||
#### In-code setting up
|
||||
|
||||
For the manual descriptor's configuration use the default example's settings and modify `tusb_sample_descriptor.c` according to your needs
|
||||
|
||||
#### Menuconfig
|
||||
|
||||
If you want to set up the desctiptor using Menuconfig UI:
|
||||
|
||||
1. Execute in the terminal from the example's directory: `idf.py menuconfig`
|
||||
|
||||
2. Turn off `Set up a USB descriptor manually in code` parameter at `Example Configuration`
|
||||
|
||||
3. Folow to `Component config -> TinyUSB -> Descriptor configuration` for all available configurations.
|
||||
|
||||
### 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:
|
||||
|
||||
```
