字集成电路讲座2在发一个，有3个，这是第二个~

[henzhuanjusvpwm.rar] - 一个基于矢量控制的无速度传感器MATLAB仿真模型。

[data-bulktransfer.rar] - 数据采集程序，采用批量传输，包括主机程序，固件源程序，驱动程序。出自《usb2.0原理与工程开发》我现在需要USB键盘方面的源程序，如果你-Word of integrated circuits 2 in the hair of a lecture, there are three, which is the second ~ [henzhuanjusvpwm.rar]- based on the vector control without a speed sensor MATLAB simulation model. [data-bulktransfer.rar]- data collection procedures, the use of bulk transport, including mainframe, firmware source code, driver. From　usb2.0 Principle and Project Development,　I now need to source USB keyboard area, if you
