ADC-16 USER GUIDE
A program can define multiple frames. For example, an application may define a FRAME with
different start-stop channels or use KSETCHNGARY to define a FRAME with the gain and channel
sequence specified in a channel-gain array.
6.5 LIST OF CALLS
This list groups the Calls according to the categories of Driver lnitiuliuztion
, General Driver
Functions
,
Frame Management, Operating Funcfions , and Frame Parameters
.
For definitions of Call Driver terms,
refer to Section 6.6.
Driver Initialization
These functions are mandatory and are typically called once, at the beginning of the application
program, before all other driver function calls. The Driver Initialization functions first verify that the
Board is at the selected base I/O address, and then they initialize both the hardware and software.
ADC-16 Driver Initialization functions are as follows:
ADC16DevOpen
ADClbGetDevHandle
KDASDevInit
Initialize a DAS driver using a configuration file.
Get a handle to the logical device associated with an adapter card.
Initialize a
DAS
driver and all aspects of the Board to a defined state.
General Function
KGetVer
Get driver specification and driver revision levels.
Frame Management
To perform multiple-sample Analog 1 / 0 or Digital Output, you must first get a Frame from the driver
through a Frame Management call. After obtaining a particular frame, you set it up using both the
Frame Management and Parameter Functions.
KGet ADFrame
KGetDOFrame
KChkFrame
KFreeFrame
KInitFrame
KClearFrame
Clears the specified frame.
Get a logical Frame for Analog to Digital (A/D) operations.
Get a logical Frame for Digital Output operations.
Check the parameters in a frame for validity.
Release a no longer used frame to the driver.
Initializes the specified frame to a predefined state.
Operating Functions
iMMEDiATE OPERATlONS
The following functions do not require a Frame.
KADRead
Read a single A/D input value.
