udevのrules追加

[AiriYokochi]

現在は"CP2102"のデバイスを見つけて接続する。 同時に複数のCP2102のデバイスがある場合に対応するため、rulesを書く

1. 99-lidar-ld06.rulesを作成

SUBSYSTEM=="tty", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea60", SYMLINK+="ttyLD06"

2. /etc/udev/rules.d配下にコピー

   sudo cp 99-lidar-ld06.rules /etc/udev/rules.d/
   sudo service udev reload

3. LiDARを指し直して/dev/ttyLD06が存在することを確認する

方法をREADMEに追記する。

SUBSYSTEM=="tty"は必須
