I having some problem to drive a PS3000 (3424) device with LabWindows, I use the PS3000.lib from PS3000sdk_f10_5_0_11 download from the website but I can't initialize the probe with the fonction PS3000_set_channel().
I'm sure I communicate with oscilloscope but can't get back value from the probe.
You need to check the return codes for each function to see they are OK, and then once you get a 1 returned by the ps3000_ready call you can then use ps3000_get_values call to retrieve the data.
If this doesn't work then we need to know exactly what your issue is, what you are expecting to happen but isn't.
For test my program I send a sine signal to Picoscope so in return all fonctions return 1 then ps3000_get_values return random values between 32767 and -32767, I know it's normal before convert in volts but I'm expecting a sine signal. It's for that I think I collect noise data instead of sine signal.
