6.4.20.4 Software-trigger DAC Conversion — AIOstartDACconversion
Provides a tick of the software clock for a DAC channel group. This is only effective when the
DAC group’s conversion trigger source has been set to CNV_SW and the DAC is being
operated in certain modes. It applies when an interrupt has been set up to drive the DAC in
FIFO mode. It also applies when a waveform has been loaded into the DAC hardware’s
waveform playback buffer. This only applies to card types that have specific support for these
operations.
SUPPORTED IN VERSION 4.20 ONWARDS.
i = AIOstartDACconversion (h, Group)
where h short: board handle as issued by the
registerBoardEx function.
Group short: DAC channel group.
Returns short: OK
or ERRHANDLE

6.4.21 Support for HP VEE
6.4.21.1 Timer Counter Functions In HP VEE.
As HP Vee does not support passing of float types, there are versions of some of the TC functions
that use parameters of type double instead of float. These just call the normal float versions
internally. These functions are:
 TCVgetRatio (calls TCgetRatio)
 TCVsetMonoShot (calls TCsetMonoShot)
 TCVsetAstable (calls TCsetAstable)
 TCVgetExtPeriod (calls TCgetExtPeriod)
 TCVgetExtFreq (calls TCgetExtFreq)
 TCVgenerateFreq (calls TCgenerateFreq)
 TCVgeneratePulse (calls TCgeneratePulse)
 TCVgenerateAccFreq (calls TCgenerateAccFreq)
 TCVmultiplyFreq (calls TCmultiplyFreq)
 TCVdivideFreq (calls TCdivideFreq)
 TCVsetDCO (calls TCsetDCO)
