PCIS-DASK Overview ? 5

AI_ContReadChannel

Performs continuous A/D conversions on the specified analog input

channel at a rate as close to the rate you specified.

AI_ContScanChannels

Performs continuous A/D conversions on the specified

continuous

analog input channels at a rate as close to the rate you specified.

This function is only available for those cards that support auto-scan

functionality.

AI_ContReadMultiChannels

Performs continuous A/D conversions on the specified analog input

channels at a rate as close to the rate you specified. This function is

only available for those cards that support auto-scan functionality.

AI_ContReadChannelToFile

Performs continuous A/D conversions on the specified analog input

channel at a rate as close to the rate you specified and saves the

acquired data in a disk file.

AI_ContScanChannelsToFile

Performs continuous A/D conversions on the specified

continuous

analog input channels at a rate as close to the rate you specified

and saves the acquired data in a disk file. This function is only

available for those cards that support auto-scan functionality.

AI_ContReadMultiChannelsToFile

Performs continuous A/D conversions on the specified analog input

channels at a rate as close to the rate you specified and saves the

acquired data in a disk file. This function is only available for those

cards that support auto-scan functionality.

AI_ContVScale

Converts the values of an array of acquired data from an continuous

A/D conversion call to the actual input voltages.

AI_ContStatus

Checks the current status of the continuous analog input operation.

AI_EventCallBack

Controls and notifies the user’s application when a specified DAQ

event occurs. The notification is performed through a user-specified

callback function.

2.3.4 Asynchronous Analog Input Monitoring Functions

AI_AsyncCheck

Checks the current status of the asynchronous analog input

operation.

AI_AsyncClear

Stops the asynchronous analog input operation.

AI_AsyncDblBufferMode

Enables or Disables double buffer data acquisition mode.

AI_AsyncDblBufferHalfReady

Checks whether the next half buffer of data in circular buffer is

ready for transfer during an asynchronous double-buffered analog

input operation.

AI_AsyncDblBufferTransfer

Copies half of the data of circular buffer to user buffer. You can

execute this function repeatedly to return sequential half buffers of

the data.

AI_AsyncDblBufferOverrun

Checks or clears overrun status of the double-buffered analog

input operation.

2.4 Analog Output Function Group

2.4.1 Analog output Configuration Functions

AO_6208A_Config

Informs PCIS-DASK library of the current range selected for the analog

output operation of PCI6208A. You must call this function before calling

function to perform current output operation.
