// 设备需要支持的特性 (2022-02-24)
|
||
//
|
||
// 1、每台设备应该有唯一的序列号，并可读取，用以精确定位连接到计算机上的每一台设备，
|
||
// 方便多台设备连接到计算机上时，插拔后实现机器状态（配置参数）的自动恢复
|
||
//
|
||
// 2、设备启动后，应该由设备上的驱动进行默认参数的设置，以支持按键扫描功能（由设备主动发起的扫描）
|
||
//
|
||
// 3、设备的所有配置参数都应该可读，以满足用户对设备实时状态的监控
|
||
//
|
||
// 4、设备要支持“reset”命令，以使设备在发生软硬件错误时，尽可能通过软件方式重置到正常状态
|
||
//
|
||
// 5、可以考虑在每一段数据的前面添加数据头信息，以表明这段数据的属性（状态数据、图片数据……），
|
||
// 为支持异步IO特性奠定基础
|
||
//
|
||
// 6、设备的基本通信（设备类型……信息访问）需要保持健壮，不能因为上位机的通信异常导致信息错乱

||
