...使用2个外部中断口来接增量型旋转编码器； 9. 蜂鸣器接口 使用一个PWM输出来控制蜂鸣器； 10. GPIO接口 至少预留出32个GPIO口用于外部设备的控制，如键盘输入，指示灯输出，三态安全开关输入，三档选择开关输入等； 基本驱动需求 1. 旋转编码器输入驱动 旋钮编码器驱动要求能判断编码器旋转方向，目前这两个GPIO口不给上层读取, 直接由驱动发送按键值，就是加入LINUX的输入事件，正向旋转发送键值59，反向旋转发送键值60，从event0读取。 2. RS485驱动 RS485需要1个方向控制脚，当向对应的UART发送接收数据时，方向脚能自动实现方向控制。 3. 蜂鸣器驱动 蜂鸣器驱动要求能设置PWM输出的频率，输出的时间，输出时间到了自动关闭PWM输出。 4. 薄膜按键驱动和USB键盘驱动 预留2
