Setting up ESP32 IDF with ADF in PlatformIO

Introduction

Currently PlatformIO doesn't support ADF natively, so there are some steps to get it working. You can just clone this repo and start using it, but I have also listed the steps below.

Note: currently the espressif32 is seto to 6.6.0 in platformio.ini, this is just as I know this version works.

To do it yourself

(you can look at the git history of project to see the steps taken too)

1. Create a new Platform IO project
2. Add ESP-ADF submodule with this command: git submodule add https://github.com/espressif/esp-adf.git esp-adf
3. Clone all nested submodules with this command: git submodule update --init --recursive
4. Setup platformio.ini settings:

board_build.embed_txtfiles = 
  esp-adf/components/dueros_service/duer_profile
    
build_flags =
  -D CONFIG_ESP32_CORVO_DU1906_BOARD
  -I lib/esp_peripherals/

build_unflags = 
  -Wl,--end-group

5. Add ADF components to root CMakeLists.txt: list(APPEND EXTRA_COMPONENT_DIRS "esp-adf/components")
6. Change setting in sdkconfig.esp32dev: CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY=y
7. Change setting in sdkconfig.esp32dev: CONFIG_FREERTOS_UNICORE=y (This was needed in espressif32 6.6 but not 6.5)

Notes:

• You can just move esp-adf/components to /components and don't need full git repository
• You don't need esp-adf/esp-idf (typically old version): git submodule deinit esp-idf

Optional add example

1. Add to CMakeLists.txt: set(COMPONENT_SRCS adf_music.mp3)
2. Add to platformio.ini: board_build.partitions = partitions.csv
3. Add data/adf_music.mp3
4. Add partitions.csv
5. Use main.c attached
6. Make sure to "Upload Filesystem Image"
