DDC101评估装置的PC接口板

The DDC101 Evaluation Fixture is a modular design. With
the use of the common DDC101 Evaluation Fixture PC
Interface Board, different Device Under Test (DUT) Boards
may be used. Different DUT boards can be used to evaluate
single or up to 32 DDC101s in any package type. Design of
the DUT boards and their use are detailed in the DDC101
Evaluation Fixture product data sheet.
This application note focuses on how to communicate directly
to the PC Interface Board through a PC’s printer port.
This communication is used to configure the PC Interface
Board as well as to configure and retrieve data from the
DDC101s on the DUT Board. This will allow the user to
write custom software to create user specific, extended
capabilities not available in the standard program.
The software for the DDC101 Evaluation Board was written
in Turbo Pascal®. The code can be readily modified to be
used with other languages. All software examples listed use
Turbo Pascal syntax.
