# Making USB sound card using Raspberry pi pico
Capture audio from a microphone on your [Raspberry Pi Pico](https://www.raspberrypi.org/products/raspberry-pi-pico/) or any [RP2040](https://www.raspberrypi.org/products/rp2040/) based board. 🎤
## Hardware
* RP2040 board
* [Raspberry Pi Pico](https://www.raspberrypi.org/products/raspberry-pi-pico/)
* Microphones
* I2S
* [inmp441]
* PDM
* [PDM mic](https://learn.adafruit.com/adafruit-pdm-microphone-breakout/overview)
* DAC
* [PCM5102A](http://www.kosmodrom.com.ua/el.php?name=PCM5102A-Modul)
* [UDA1334A](https://learn.adafruit.com/adafruit-i2s-stereo-decoder-uda1334a)
* LCD
* SSD1306
* Buttons
* LEDs
* WS2812
* Resistors
## Examples
See [applications]:
* [stereo_microphone_i2s]( stereo_microphone_i2s )
* [stereo_microphone_pdm]( stereo_microphone_pdm )
* [stereo_speaker]( stereo_speaker )
## Cloning
```sh
git clone https://github.com/denisgav/rpi_usb_sound_card.git
```
## Building
1. [Set up the Pico C/C++ SDK](https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf)
2. Set `PICO_SDK_PATH`
```sh
export PICO_SDK_PATH=/path/to/pico-sdk
```
3. Create `build` dir, run `cmake` and `make`:
```
mkdir build
cd build
cmake .. -DPICO_BOARD=pico
make
```
4. Copy example `.uf2` to Pico when in BOOT mode.
