daqAdcSoftTrig
DLL Function
daqAdcSoftTrig(DaqHandleT handle);
C
daqAdcSoftTrig(DaqHandleT handle);
Visual BASIC
VBdaqAdcSoftTrig&(ByVal handle&)
Delphi
daqAdcSoftTrig(handle:DaqHandleT)
Parameters
handle
Handle to the device to which the ADC software trigger is to be applied
Returns
DerrNoError
- No error (also, refer to
API Error Codes
on page 11-39)

Used With
All devices
daqAdcSoftTrig
is used to send a software trigger command to the Daq* device. This software
trigger can be used to initiate a scan or an acquisition from a program after configuring the software
trigger as the trigger source. This function may only be used if the trigger source for the acquisition
has been set to
DatsSoftware
with the
daqAdcSetTrig
function.
daqAdcTransferBufData
DLL Function
daqAdcTransferBufData(DaqHandleT handle, PWORD buf, DWORD scanCount,
DaqAdcBufferXferMask bufMask, PDWORD retCount);
C
daqAdcTransferBufData(DaqHandleT handle, PWORD buf, DWORD scanCount,
DaqAdcBufferXferMask bufMask, PDWORD retCount);
Visual BASIC
VBdaqAdcTransferBufData(ByVal handle, buf%, ByVal scanCount&, ByVal bufMask&,
retCount&);
Delphi
daqAdcTransferBufData(handle: DaqHandleT; buf : PWORD, scanCount : DWORD,
bufMask: DaqAdcBufferXferMask; retCount: PDWORD);
Parameters
handle
Handle to the device for which the ADC buffer should be retrieved.
buf
Pointer to an application-supplied buffer to place the buffered data.
scanCount
Number of scans to retrieve from the acquisition buffer.
bufMask
A mask defining operation depending on the current state of the acquisition buffer
retCount
A pointer to the total number of scans returned, if any.
Returns
DerrNoError
- No error (also, refer to
API Error Codes
on page 11-39)

Used With
All devices
daqAdcTransferBufData
requests a transfer of
scanCount
scans from the driver-allocated
ADC acquisition buffer to the specified user-supplied buffer. The
bufMask
parameter can be used
to specify the conditions for the transfer as follows:
•
DabtmWait
- Instructs the function to wait until the requested number of scans are available
in the driver-allocated acquisition buffer. When the requested number of scans are available,
the function will return with
retCount
set to
scanCount
, the number of scans requested.
ADC data will be returned in the memory referred to by the
buf
parameter.
•
DabtmNoWait
- Instructs the function to return immediately if the specified number of scans
are not available when the function is called. If the entire amount requested is not available,
the function will return with no data and
retCount
will be set to 0. If the requested number
of scans are available in ADC acquisition buffer, the function will return with
retCount
set
to
scanCount
, the number of scans requested. ADC data will be returned in the memory
referred to by the buf parameter.
•
DabtmRetAvail
- Instructs the function to return immediately, regardless of the number of
scans available in the driver-allocated acquisition buffer. The
retCount
parameter will
return the total number of scans retrieved.
retCount
can return anything from 0 to
scanCount
, the number of scans requested. ADC data will be returned in the memory
referred to by the
buf
parameter.
The driver-allocated acquisition buffer must have been allocated prior to calling this function. This
is performed via the
daqAdcTransferSetBuffer
. Refer to
daqAdcTransferSetBuffer
for more details on specifying the driver-allocated acquisition buffer.
