5.21 _7300_DO_PG_Start
@ Description
The function will perform pattern generation with the data stored in
buff_ptr. It will takes place in the background which will not be stop
until your program execute _7300_DO_PG_Stop function to stop
the process.
@ Syntax
Visual C/C++ (Windows 95)
int W_7300_DO_PG_Start (int card_number, void
*buff_ptr, U32 count)
Visual Basic (Windows 95)
W_7300_DO_PG_Start (ByVal card_number As Long,
buff_ptr As Any, ByVal count As Long) As
Long
C/C++ (DOS)
int _7300_DO_PG_Start (int card_number, void
*buff_ptr, U32 count)
@ Argument
card_number :The card number of the cPCI/PCI/PCIe-7300A
card.
buff_ptr :the start address of the memory buffer to store the out-
put data of pattern generation.
** This memory should be double-word alignment
count :the total number of pattern generation samples. The size of
the sample depends on the port configuration. For example, if port
is set as DO32, each sample contains 4 bytes; if port is set as
DI16DO8 or DI8DO8, each sample is 1 byte.
@ Return Code
NoError
PCICardNumErr
PCICardNotInit
DMATransferNotAllowed
InvalidDIOCount
