やってること

STM32 Nucleo-F746ZGボードでPWM出力可能な全ピン32ヶ所からPWMを出す。

こちらの記事とは違って、ボードファイルから作るパターンを試してみた。 実行結果は変わらない。

作成

構成は以下の通り

  • prj_f746
    • boards
      • arm
        • prj_f746
          • prj_f746_defconfig
          • prj_f746.dts
          • prj_f746.yaml
          • Kconfig.board
          • Kconfig.defconfig
          • board.cmake
          • support/
            • openocd.cfg
    • src
      • main.c
    • CMakeLists.txt
    • prj.conf

ただし

  • src
    • main.c
  • CMakeLists.txt
  • prj.conf

は前と変わらないため省略。

前回作成していたapp.overlayは、今回ボードのdtsファイルを自由に記述できることから、内容をその中に組み込むこととした。

boards/arm/prj_f746/prj_f746.defconfig

ボード固有のコンフィグを設定。 プロジェクト内で必要がある場合は、prj.confに記載することによって追記できる。

zephyr/nucleo_f746zg_defconfig at main · zephyrproject-rtos/zephyr · GitHub

boards/arm/prj_f746/prj_f746.dts

ボード内のデバイスツリーを記入。

大半はf746の公式デバイスツリーをそのまま使っている。

zephyr/nucleo_f746zg.dts at main · zephyrproject-rtos/zephyr · GitHub

ただし、前回app.overlayに追記した内容を今回はあらかじめ組み込んでいる。
