Hi !!! I am a rookie in the domain but i have got a Ni pci 6602 Card. I'm programming with with Visual C++. With one counter i generate a signal1 with a choosen frequency and with another counter i' m receiving an external signal2.

Hi,

See the following links about edge counting they might help you for your problem:

These document are mostly related to LabVIEW but it should be working the same way with Visual C++ if you are using the DAQmx API.

Hope this help,

Also there are good references for C programming with DAQmx contained within the DAQmx driver.  When you install it, there is a C reference help located at Start >> Programs >> National Instruments >> NI-DAQ >> NI-DAQmx C Reference Help.

Some examples are also installed with the driver.  These will be located at C:\Program Files\National Instruments\NI-DAQ\Examples.
