Compile & Debug

In order to compile the PicoW USB Audio to Bluetooth Adapter firmware from source code, you need to follow these steps:

1. Prepare your environment: Make sure that you have a working development environment for Raspberry Pi Pico projects. This includes having the required compiler and tools installed. You may refer to the Getting started with Raspberry Pi Pico guide for detailed instructions.

2. Set the necessary environment variables: Before you can build the project, you need to set two environment variables: PICO_SDK_PATH and PICO_EXTRAS_PATH. For example:

export PICO_SDK_PATH=~/pico-sdk
export PICO_EXTRAS_PATH=~/pico-extras

1. Build the project: After setting up your environment, navigate to the project directory in a terminal and run the provided build script:

./build.sh

This script should compile the project and produce a UF2 firmware file that you can flash onto your Pico W.

1. Debug Serial input/output: You can use uart to see the debug info. Connect the GPIO 0 and 1 as TX and RX. To enable BTstack's serial input, you can uncomment HAVE_BTSTACK_STDIN under btstack_config.h
