MarsCat 开发手册

开发前的准备

• 连接显示器、鼠标、键盘

• 连接wifi后，用ssh或vnc等远程连接

  注 账户和密码都是 pi

• 在开发前需要停止猫咪的开机自启服务

  cd ~/marsai
  ./tools/stop-systemd-services.sh
  ./tools/disable-systemd-services.sh
  

• 如果你要放弃了，重启猫的服务

  cd ~/marsai
  ./tools/enable-systemd-services.sh
  ./tools/start-systemd-services.sh

eyes.display_eye(ball_num = 1, lid_num = 1, ball_type = 'eye_ball', dx = 0, dy = 0)

"""
args:
    ball_num --> int:
        normal eye_ball : 1~10 [e.g. eye_ball]
	eyes with animation : 1~3 [e.g. flip, hug, ball, etc]
