Hi Martyn, Thanks for the additional information. The issue was more related to QT. I was missing the library path in my DYLD_LIBRARY_PATH environment variable. Once that included, it worked. I got this information from the QT user forum.

I am integrating PicoScope support into a QT application. Using QLibrary, I am able to load the library but when I attempt to get a pointer to the ps2000aOpenUnit function, the function is not found. //open unit and show splash screen ps2000aLib = new QLibrary( QString(PICOSCOPE_LIBRARY_DIR_PATH) + ...

Hello, I am looking to see the effective or average voltage of a PWM signal. My PWM is controlling fet switching the voltage across a solenoid. To simplify my interpreting the data, I'd like to be able to see the PWM average which should correspond to the average voltage across the solenoid. I have ...

Forgive me for this total n00bie question; I haven't programmed in MFC in a while. I compiled and ran the sample application no problem. Now I want to write my own in MFC. I wrote a wrapper class to you ps3000.c & .h. Right now, it has only a constructor and initialize function, which calls ps3000_o...
