5.3 EXAMPLE PROGRAMS
Included with ADLIB WIN is an extensive set of programming examples that provide conceptual
interpretations of interfacing to ADLIB to assist in the development design of the user application. Each
example program is designed to exercise a specific area of the library to simplify the understanding of the
example's specific concept. See also, the comments provided at the beginning of each example program file
for detailed descriptions.
The following is the list of example programs:
Example programs are also provided for each specific board type, and are not necessarily generic to all
boards. The examples are located in each board (NAME) directory.
\Adlai01 examines the BUFFER_DONE message response handler
\Adlai02 examines the User polling of the BUFFER_DONE flag.
\Adlai04 examines the ABOUT Trigger mode.
\Adlai05 examines the BURST/SCAN MODE option.
\Adlai07 examines the Software Transfer method.
\Adlai08 examines the CALLBACK buffer response handler (MSC only).
\Adlda01 examines the Software Transfer method.
\Adlda02 examines the Single DAC BUFFER_DONE message response handler
\Adlda03 examines the Dual DAC BUFFER_DONE message response handlers
\Adldio01 examines the Software Transfer Digital Input/Output ports 0 & 1.
\Adldio23 examines the Software Transfer Digital Input/Output ports 2 & 3.
\Adlctr01 examines the Counter IN and Counter OUT functions.
