I'm a new user of Labview and a I have a NI-USB 6221 card . I want to generate a TTL signal so I wanted to use the examples you give in
http://zone.ni.com/devzone/cda/tut/p/id/2991 Pulse Width Modulation (PWM) Using Daqmx and Labview. When I am trying to use the vi in the zip file daqmx_pwm_examples.zip at the end of the page, Labview tells me some VIs are missing, such as "DAQmx Write (Counter Frequency 1Chan 1Samp).vi", "Daqmx write.vi ", "DAQmx Is task done.vi" and others. Did I miss something during the installation of Labview 2009 ?
Thank you for the help.
Guilhem Bordes.
