Raspberry Pi 4 Connected to LabVIEW but GPIO pin not working

[Seperthar1]

I got a Raspberry Pi 4 today and I am very new. I have Buster version 10 installed (it came pre-loaded on the SD card from the kit). I have LabVIEW 2020 Community Edition (not SP1). I was able to connect to my raspberry pi in the LINX target config and I updated the software via the target config. After that I added my raspberry pi to my project and connected to it successfully. When I try to run the blink VI, it doesn't work. I have the LED setup correctly with a 220 ohm resistor, wiring is correct on pin 7 (4th pin down on the left if looking with usb ports on top). Any ideas on what could be wrong?

Hi,

There is information about the Raspberry PI GPIO pinout here: 

https://www.raspberrypi.org/documentation/usage/gpio/

You could test the LED with series resistor by connecting it to pin 1 (3.3V) instead of pin 7.

So, the I tested the 3.3V and 5V pins and got no response from the LED. I tested the LED on my Arduino 5V pin and it worked fine. Is there something you need to do to activate the GPIO pins?

Are you setting the Digital Output Channel to 7 on the LabVIEW UI ?

Hello, could you tell me how you managed to configure the Raspberry Pi 4 to LINX, I'm having difficulties

I had the Pi backwards. Everything is working now.

Mine was easy because I bought a kit with an OS pre-loaded onto an SD card. So I just installed that and then updated the firmware via the target configuration.
