第1步 - 通过ssh，或者串口终端进入开发板的命令行，从 github 上下载BakeBit代码: cd ~git clone https://github.com/friendlyarm/BakeBit.git
第2步 - 使用如下命令在开发板上安装BakeBit:
cd BakeBit/Scriptchmod +x install.sh./install.sh
第3步 - 重启开发板:
reboot
第4步 - 运行示例程序:
可以在开发板上进入 BakeBit/Software/Python目录,运行bakebit_prj_Button_And_Buzzer.py: cd ~/BakeBit/Software/Pythonsudo python bakebit_prj_Button_And_Buzzer.py
运行结果
当按下按键时，蜂鸣器会响起，松开按键时，蜂鸣器停止。
