一个linux下的usb接口源代码-a linux usb interface of the source code

作品简介:该作品与配备的多个从机构成一个计分体系,可以通过总机器读取从机器的分值.每个计分员在手上的计分从机器输入分数,则无需人手统计,就能在总机器的液晶屏上看到各位记分员给的分数. 支持多个从机同时通过USB线连接到总机.由于USB连接市场上能方便的购买,所以使用USB连接线构建计分体系. 作品作用:在各种文艺活动中的计分环节上,能方便的为计分员统计分数. -Works Introduction: the work and is equipped with a number from the body into a scoring system, the machine can read the total scores from the machine. Each scoring in the hands of the points from the machine enter the scores, you do not need manpower statistics can be in the overall machine s LCD screen to see all the scores to the scorekeeper. support multiple machines at the same time from the USB line to connect to the switchboard. USB connection as a result of the market can make it easier to buy, so use the USB cable to build a scoring system. work roles: in a variety of cultural activities in the scoring areas, can make it easier for Members of statistical scores points.

USB设备端固件程序,枚举部分是全部程序的基础和重心,只有主机对设备枚举成功后,主机才能和设备进行正常的通信 USB的枚举过程分为4个状态. 1.接入态 v主机检测到USB设备插上,击活端口,并发送复位命令(保持10ms) 2.默认态 v主机使用默认地址读取设备描述符 (GET_DESCRIPTOR) v主机分配给设备一个总在线的唯一地址 (SET_ADDRESS) 3.地址态 v主机从新的地址获取设备描述符(GET_DESCRIPTOR) v主机获取所有设备的配置描述符(GET_DESCRIPTOR) 4.配置态 v主机设置描述符(设备,配置) (SET_CONFIGURATION) v主机读取配置状态(可选) (GET_CONFIGURATION) v主机读取接口状态(可选) (GET_INTERFACE) -USB device-side firmware, enumerate all part of the foundation and focus of the procedure, only the host of equipment after the successful enumeration, the host and equipment in order to engage in normal communication USB enumeration process is divided into four status. 1. Access state v host detected USB devices plug in, hit live ports, and send the reset command (to maintain 10ms) 2. default state v Use the default address of the host to read device descriptor (GET_DESCRIPTOR) v host assigned to the equipment of a total online only Address (SET_ADDRESS) 3.
