ODriveでBLDCモーターの制御 #04 ASCII Protocol

ODriveの動作には、CANやRC PWMなどの他、UARTを使ったバイナリで通信するNative Protocolと、アスキーコードで通信通信するASCII Protocolの二種類のシリアル通信用プロトコルがあります。

仕様書をざっと見ても、更に名前からも分かる通り、ASCII Protocolの方が1回の命令のパケット長が長く、高速に通信するならNative Protocolの方が良いのでしょう。

これからロボットを自作しようという話なので、SDKかサンプルプログラムを期待するわけですが、ODriveはサンプルもツールも全部pythonで作られています。python好きなら良かったのですが、どうもpythonに抵抗があるので、どうしてもC++で書き直したいところです。

ちょうど、前回触ったArduino( C++ )がasciiプロトコルのライブラリになっているため、こちらをそのままVisualC++/MFCのプロジェクトに放り込んでみます。

接続は、ODriveオンボードのUSBではなく、GPIOのUARTにUSB-TTL変換ケーブルを使って接続しました。

ODriveオンボードのUSBの場合、ODriveの電源を落とすとシリアルポートもPC上から消えてしまうのですが、変換機を使えばポートは残るので便利かなーという理由です。あと、元になったソースがArduinoライブラリなので接続を揃えたかったというのもありますね。
GPIO1,2にTxDとRxDを接続し、GND同士を結線すれば、3本繋いで接続は完了です。

接続が出来れば、実際に通信です。アスキープロトコル、非常に簡単でした。

例えば位置制御で、「axis0のモーターを2回転回転させる。速度とトルクは指定なし」の場合は下記のコマンドを送ります。小数点は省略できます。

p 0 -2 0 0[LF]

パラメータ1つめがモーターID、2,3,4はそれぞれ、位置・速度・トルクになります。floatで少数で送ってもいいし、整数で送ってもいいです。
実際、数値を変えながら連続して送ると、モーターが回ります。

また、パラメータの書き込みの場合は、例えば「axis0の速度リミットを1000回転/秒に設定する」だと・・・

w axis0.controller.config.vel_limit 1000.0[LF]

です。
ただ、設定の場合、返り値がないのが、不安なところです。

なので、書き込んだパラメータを読み取ってみます。
例えば「axis0の速度リミットの設定値を読み取る」だと・・・

r axis0.controller.config.vel_limit[LF]

になります。送るとODriveから、値のみが文字で帰ってきます。
受け取った文字列を、atoiやatofで変換すればOKです。

帰ってきた値が設定した値になっていれば、設定がうまくいったことが分かりますね。

Native Protocolの方にはCRCなどもあるようですが、ASCII Protocolには、チェックサムやエラー処理はないので、そのあたりは割り切って使うしかないようです。ここはASCII Protocolの不安ポイントですね。

さて、これらを使って、簡単にアプリを作ってみました。

ODriveのお作法ですが、電源投入から「フルキャリブレーション」→「クローズドループ」→「ひたすら位置を送信」、という手順で動作させます。

ついでに、パラメータの読み書きが出来るので、動作中のパラメータを吐き出して、グラフ化することも可能です。

ASCII Protocolに関しては、すごく素直な感じで、サクッと実装出来ました。

あとはパラメータの読み書きが出来るので、初期設定もGUIで作っちゃったら便利かなーと思ったのですが・・・

パラメータがどうなってるのが、Odrivetoolで、全容を吐き出して、その多さに愕然としております。とりあえず、せっかく吐き出したので、忘備録として張り付けておきます。(実際の設定値は参考にならないので注意！）

とりあえず、よく使うパラメータだけ設定出来るツールにしよう(^^;A
