# How to build example for Esp32s3
|
||||
1. Load idf environment variables (eg. using the esp-idf alias `get_idf` if configured)
|
||||
|
||||
2. cd into examples directory
|
||||
```
|
||||
$ cd /tinyusb/examples/device/audio_4_channel_mic_freertos
|
||||
```
|
||||
|
||||
3. Run cmake in project directory specifying the board
|
||||
```
|
||||
$ cmake -DBOARD=espressif_s3_devkitc -B build -G Ninja .
|
||||
$ ninja.exe -C build
|
||||
```
|
||||
|
||||
4. Flash the binary onto the esp32-s3 by copy-paste of the full command output by the esp-idf build system replacing **(PORT)** with eg. /dev/ttyUSB0
|
||||
|
||||
eg.

# How to build example for Esp32s3
|
||||
1. Load idf environment variables (eg. using the esp-idf alias `get_idf` if configured)
|
||||
|
||||
2. cd into examples directory
|
||||
```
|
||||
$ cd /tinyusb/examples/device/audio_test_freertos
|
||||
```
|
||||
|
||||
3. Run cmake in project directory specifying the board
|
||||
```
|
||||
$ cmake -DBOARD=espressif_s3_devkitc -B build -G Ninja .
|
||||
$ ninja.exe -C build
|
||||
```
|
||||
|
||||
4. Flash the binary onto the esp32-s3 by copy-paste of the full command output by the esp-idf build system replacing **(PORT)** with eg. /dev/ttyUSB0
|
||||
|
||||
eg.

#### Composite CDC + UAC2 on Pico
|
||||
|
||||
This example provides a composite CDC + UAC2 device on top of a Raspberry Pi
|
||||
Pico board.
|
||||
|
||||
|
||||
#### Use Cases
|
||||
|
||||
- The CDC + UAC2 composite device happens to be important, especially in the
|
||||
amateur radio community.
|
||||
|
||||
Modern radios (`rigs`) like Icom IC-7300 + IC-705 expose a sound card and a
|
||||
serial device (`composite device`) to the computer over a single USB cable.
|
||||
This allows for Audio I/O and CAT control over a single USB cable which is
|
||||
very convenient.
|
||||
|
||||
By including and maintaining this example in TinyUSB repository, we enable
|
||||
the amateur radio community to build (`homebrew`) radios with similar
|
||||
functionality as the (expensive) commercial rigs.
|
||||
|
||||
This PR is important in bridging this specific gap between the commercial
|
||||
rigs and homebrew equipment.
|
||||
|
||||
- https://digirig.net/digirig-mobile-rev-1-9/ is a digital interface for
|
||||
interfacing radios (that lack an inbuilt digital interface) with computers.
|
||||
Digirig Mobile works brilliantly (is OSS!) and is a big improvement over
|
||||
traditional digital interfaces (like the SignaLink USB Interface). By using a
|
||||
Raspberry Pi Pico powered CDC + UAC2 composite device, we can simplify the
|
||||
Digirig Mobile schematic, drastically reduce the manufacturing cost, and
|
||||
(again) enable the homebrewers community to homebrew a modern digital interface
|
||||
with ease themselves.
|
||||
|
||||
|
||||
#### Build Steps
|
||||
|
||||
```
|
||||
cd examples/device/cdc_uac2
|
||||
|
||||
export PICO_SDK_PATH=$HOME/pico-sdk
|
||||
|
||||
cmake -DFAMILY=rp2040 pico .
|
||||
|
||||
cmake -DFAMILY=rp2040 -DCMAKE_BUILD_TYPE=Debug # use this for debugging
|
||||
|
||||
make BOARD=raspberry_pi_pico all
|
||||
```
|
||||
|
||||
|
||||
#### Development Notes
|
||||
|
||||
Please try to keep this code synchronized with the `uac2_headset` example
|
||||
included in this repository.
