# 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 with USB connectors or with exposed USB's D+ and D- (DATA+/DATA-) pins.
|
|
|
|
If the board has no USB connector, but has the pins connect pins directly to the host (e.g. with DIY cable from any USB connection cable)
|
|
|
|
```
|
|
ESP32-S2 BOARD USB CONNECTOR (type A)
|
|
--
|
|
| || VCC
|
|
[GPIO 19] --------> | || D-
|
|
[GPIO 20] --------> | || D+
|
|
| || GND
|
|
--
|
|
```
|
|
|
|
You can also use power from the USB connector.
|
|
|
|
### 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 descriptor 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. Follow `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:
|
|
|
|
```
|
|
