...使用RMII接口的PHY，所以RMII接口管脚也要预留出来，PHY使用DP83848IVV； 6. 串行通信接口 预留出1个RS232用的UART； 预留出1个RS485用的UART，另外还要预留1个管脚用来RS485的方向控制； 7. USB接口 预留出1个USB接口用来外接USB设备； 8. 旋转编码器接口 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24个GPIO作为薄膜按键的输入，目前的驱动是作为GPIO口来读取的；最好也缴入LINUX的输入事件，按不同的按键发送不同的键值，从event0读取；外接USB键盘驱动最好也从event0读取。 5. 其他GPIO驱动 每个GPIO口都可以通过驱动设置输入/输出。 6. 触摸屏驱动和外接USB鼠标驱动 7. 触摸屏驱动和外接的鼠标驱动设备文件最好固定，例如触摸屏固定使用event2，USB鼠标固定使用event3。 ENGLISH Basic Requ...
