一些驱动程序头代码：

...
BYTE ReadRegister(DEVICE_CONTEXT *pDevice,BYTE SlavAddr,BYTE SlavMode,WORD RegAddr,BYTE* pData,BYTE DataCont);

BYTE WriteRegister(DEVICE_CONTEXT *pDevice,BYTE DataCont);
...

驱动程序cpp代码片段：

BYTE ReadRegister(DEVICE_CONTEXT *pDevice,BYTE DataCont)
{
.....
}

//-----------------------------------------------------------------------------
BYTE WriteRegister(DEVICE_CONTEXT *pDevice,BYTE DataCont)
{
....
}
