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. 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:

• For adding ESP-ADF , submodule with this command: git submodule add https://github.com/espressif/esp-adf.git esp-adf
• Some of the adf components are changed for maintaing the compatiblity with ESP-IDF.
• The current board setup in main.c is for simple esp32s3 module with no codec chip which plays audio through a external audio dac.

Testing The Example

• You can copy paste any example from the ESP-ADF repo.
• Mostly examples have a option for configuring the parameters in the .c file or in menuconfig.
• Choose the correct board in the menuconfig.
• You can customize the board parameters in the respective board file present in the component folder.
• Compile and Upload and see ESP-ADF in action.
