README
README.mdM5StackChan:bit
M5ｽﾀｯｸﾁｬﾝにmicro:bitを差し込んで制御するボードです。 micro:bitのプログラミングでM5ｽﾀｯｸﾁｬﾝを動かすことができます。
M5ｽﾀｯｸﾁｬﾝの上部の2つのGroveコネクタに、この写真の向きに差し込んでください。
使用方法
M5ｽﾀｯｸﾁｬﾝには、FW/以下のプログラム(PlatformIO用)を書き込んでください。
micro:bit側のプログラム（m-asaoka-fap氏作成のカスタムブロックあり）から、M5ｽﾀｯｸﾁｬﾝを制御できます。
micro:bitとｽﾀｯｸﾁｬﾝ(M5Stack)の間はUART通信(115200bps・N81、コマンド区切りはLF/0x0a/'\n'）で以下のような制御コマンドを送って制御します。micro:bit側のカスタムブロックもあり、MakeCoreで組み込んで使用できます。
- 動作の制御
- Xnn : パン動作（横方向）nn=角度、範囲＝-90〜90（正面=0）
- Ynn : チルト動作（縦方向）nn=角度、範囲=0〜30（正面=0から上向きへ）
- 顔の制御
- Txxxx : 吹き出しに”xxxx”と表示し、それにあわせて口が動く
- En : 表情を設定。n=0〜5 (0=Angry, 1=Sleepy, 2=Happy, 3=Sat, 4=Doubt, 5=Neutral)

Questions
How big is the ScBit2 PCB?
It measures 56 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ScBit2 use?
8 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ScBit2 KiCad files?
From the akita11/M5StackChanBit repository on GitHub, at the commit this page was made from: the board is PCB/ScBit2.kicad_pcb and its schematic PCB/ScBit2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ScBit2 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
