Counter Example

30 Dec 2002 (Updated 28 Sep 2011)

An example using generic dll calling to use the counter on an NI daq card.

File Information
Description	UPDATE: Beginning with R2011b, the Data Acquisition Toolbox offers direct support for counters on most NI data acquisition card. ------- This example shows how to access the counter subsystem of an NI AI or MIO card. This feature is not supported by the Data Acquisition Toolbox™, but can be easily implemented with direct calls to the NIDAQ driver with generic DLL calling. This counter application can be run while the Data Acquisition Toolbox is accessing the other hardware subsystems (analog input, analog output, and digital input/output). This allows you to build a complete measurement system directly within MATLAB®. The zip file contains two directories - one if you are running R13, another if you are using R13SP1 or newer.
