# Knob Panel Example

A GUI Demo designed for knob panel which has the voice playback function.

## How to use example

Please first read the [User Guide](https://docs.espressif.com/projects/esp-dev-kits/zh_CN/latest/esp32c3/esp32-c3-lcdkit/user_guide.html) of the ESP32-C3-LCDkit to learn about its software and hardware information.

The example can be directly flashed to the board by [ESP Launchpad](https://espressif.github.io/esp-launchpad/?flashConfigURL=https://dl.espressif.com/AE/esp-dev-kits/config.toml).

### Hardware Required

* An ESP32-C3-LCDkit development board with subboard and speaker
* An USB Type-C cable for Power supply and programming

### Build and Flash

Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.

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

See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.

2. In "App" page, short press to confirm and long press to exit.

## Troubleshooting

* Program upload failure
    * Hardware connection is not correct: run `idf.py -p PORT monitor`, and reboot your board to see if there are any output logs.
    * The baud rate for downloading is too high: lower your baud rate in the `menuconfig` menu, and try again.
    * Error message with `A fatal error occurred: Could not open /dev/ttyACM0, the port doesn't exist`: Please first make sure the development board connected, then make board into "Download Boot" by following steps:
        1. keep press the knob
        2. short press "REST(SW3)" button
        3. release the knob
        4. upload program and reset
* Program runtime failure
    * Error message with `i2s_common: i2s_channel_disable : the channel has not been enabled yet`: This is a normal message, please ignore it.
