因为ULPI接口即要进行USB数据传输又要进行寄存器读写控制,数据传输才是重点,要保证高数据传输带宽所以要尽量减少寄存器读写占用的带宽,所以增加set clr两种寄存器操作模式,而不是只有rd和wr,不同的操作通过寄存器地址区分。 1.4立即寄存器 1.4.1 VID和PID 地址:00h-03h只读。 1.4.2 功能控制Function Control 控制PHY...

注意以下代码没有考虑一个描述符发送2或者3帧的情况,按需求添加描述符中PID配置即可。 /*** \fn usbd_ep_write_0* 端点发送数据* \param[in] epnum 端点地址* \param[in] buffer 发送缓冲区* \param[in] size 发送长度* \param[in] flag 1第一次发送 0后续发送* \return 总是返回0*/staticint us...
对于描述符我们参考《DesignWare Cores USB 2.0 Hi-Speed On-The Go (OTG) Programming Guide.pdf》或者前面的dwc2驱动系列文章。 对于控制传输IN的描述符设置如下,两个4字节的参数,第一个即Status第2个即buffer指针。其中Buffer指针最好是4字节对齐。Status则重点关注L和SP的组合。BS和TxSts硬件会更新状态,软件...
