how to control a pic with labiew and USB-6008

[Brenno_walker]

Hi everyone im new to labview and i was wondering if i could get some help. I have a PIC16f628a that is generating a 3phase PWM signal which frequency is varied by logic high or low input on one of the PORTS,  i aim to use the digital PORT0 on my USB-6008 to produce these high or low values. I have tired to do this using the test panel but the line goes to ground when i connect it to the PIC. any help will be gratefully apreciated on how to control the PIC with Labview and the USB-6008

Regards Brendan

First disconnect them and make sure, each one works correctly. If i understand correctly it will be easy to test it manually.

Make sure the Port of USB-6008 is an output and the Port of PIC is set as input.

It is trivial. You should not have any problems

Also they need common ground.

And check that voltage does not go higher than PIC can handle

thanks for your help. i forgot to mention i was using an external power supply with the PIC, i used the USB-6008 5V supply to power it and fixed the issue, think it was a probelm with the signal reference. silly mistake haha
