这是直流电机的驱动程序，可控制智能小车寻迹

PDIUSBD12的接口芯片固件程序 可直接使用-PDIUSBD12 firmware interface chip can directly use

使用PortTalk及经过改良的函数集进行2KXP下IO口的直接访问，在你的代码中调用OpenCurProcessIOAllAccess(CurWnd: THandle)或者OpenCurrentProcessIOAllAccess(PID: THandle)即可，CurWnd是窗口句柄，PID是进程句柄。-use PortTalk and improved function set for the next IO 2KXP directly to the mouth, in your code calls OpenCurProcessIOAllAccess (CurWnd : THandle) or OpenCurrentProcessIOAllAcces s (PID : THandle) can be, CurWnd is a window handle, PID is the process handle.
