请教d12程序

2万 · 2007-9-4 14:21

zlg书上的

比如get status
过程是
主机发setup包，d12产生ep0 out中断 mcu读8字节
主机发in包 d12产生ep0 in中断 mcu发送数据给主机
主机再应答

Ep0 out中断：读取8字节并分析出setup包类型
Ep0 in中断：发送一串数据给主机

看zlg书中是ep0 out分析出setup包后
进入请求处理函数有写端点语句发送数据
而且是用局部数组
如果在请求处理中已经发送了数据
那么在ep0 in中断中mcu还发什么数据给主机呢？
我觉得应该在请求处理中只把数据填充到数组中
等待发生enp in中断时写给主机吧
这个数据（设备状态）到底是请求处理中还是ep0中发送？
