# Kidsbox
|
|
|
|
This is a battery-powered rfid-tag-controlled audio player meant to be used by kids.
|
|
You can bundle audio-files to rfid tags and let your kids choose the music or audiobook of their favour by placing the corresponding tag atop of the box.

## Todo
|
|
|
|
- Volume buttons
|
|
- Playlists
|
|
- Pausing
|
|
- ... I have a lot of ideas :)
|
|
|
|
## Setup
|
|
|
|
1. Install ESP-ADF and ESP-IDF according to the [install guide](https://docs.espressif.com/projects/esp-adf/en/latest/get-started/index.html#installation-step-by-step).
|
|
2. Clone this repository and `cd` into the repository directory.
|
|
3. `git submodule init --recursive`
|
|
3. `cd device`
|
|
4. Make sure that you have `idf.py` available in your environment. This is described in the install guide.
|
|
5. Execute `idf.py build` to compile, `idf.py build flash monitor` to flash it to your board.

|
|
|
|
|
|
### Hardware Setup
|
|
|
|
The peripherals must be configured for:
|
|
|
|
- SD Card
|
|
- RFID-module
|
|
- Vol+/- buttons
|
|
|
|
The ESP32-LyraT board has only a few exposed GPIO pins. To save pins, the SD-Card reader runs only in 1-Wire mode. I have actually no idea what the limitations and differences are, but I didn't encounter any problems yet.
|
|
|
|
#### DIP-Switch
|
|
|
|
The switches must be exatly in the positions outlined in the table.
|
|
|
|
|Number|Setting|Purpose|
|
|
|-|-|-|
|
|
|1|OFF|Disconnects GPIO 12 from SD-D2|
|
|
|2|OFF|Disconnects GPIO 13 from SD-D3|
|
|
|3|OFF|Connects GPIO 15 to SD CMD|
|
|
|4|ON|Connects GPIO 13 to the JTAG header|
|
|
|5|ON|Connects GPIO 12 to the JTAG header|
|
|
|6|OFF|Connects GPIO 13 to SD CLK|
|
|
|7|OFF|Disconnects GPIO 12 from the AUX-in-detection|
|
|
|8|OFF| - |
