70 C/C++ Libraries5.24 _7200_DO_DMA_Start@ DescriptionThe function will perform digital output N times with DMA datatransfer by using the following four sampling modes:1. Pacer trigger (internal timer trigger, TIME 1)2. Internal timer pacer with O_REQ enabled3. O_REQ & O_ACK handshakingIt takes place in the background which will not be stopped until theNth conversion has been completed or the program executes the_7200_DO_DMA_Stop function to stop the process. After execut-ing this function, it is necessary to check the status of the opera-tion by using the function _7200_DO_DMA_Status.@ SyntaxVisual C++ (Windows 95)int W_7200_DO_DMA_Start (U8 mode, U32 count, U32handle, Boolean repeat)Visual Basic (Windows 95)W_7200_DO_DMA_Start (ByVal mode As Byte, ByValcount As Long, ByVal handle As Long, ByValrepeat as Byte) As LongC/C++ (DOS)int _7200_DO_DMA_Start (U8 mode, U32 count, U32*do_buffer, Boolean repeat)@ Argumentmode: Digital output trigger modesDO_MODE_0: Internal timer pacer (TIME 1)DO_MODE_1: Internal timer pacer with O_REQ enableDO_MODE_2: O_REQ & I_REQ handshakingcount:the sample number of digital output data (in samples, not inbytes)handle (Win 95): the handle of system DMA memory.
