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
