Raspberry Pi & DMM Control

[VInoob]

Hello,

I am using the linx hobbyist toolkit and it works well for controlling the raspberry pi, however I also want to control an Agilent 34405 and the raspberry pi together. 

What is the best way of doing this? The easiest way I know of is just to have two separate projects. Ideally, I'd prefer it to be under the same project/application.

To control your Agilent DMM, use VISA libraries.

You can use both in the same application, just maintain both the VISA references separately and use them appropriately with their commands.

So if I place my Agilent subvis into the raspberry pi application would I then connect the usb cable to my pc or raspberry pi? My assumption is raspberry pi. Will the library also be uploaded to the raspberry pi?

I am hoping to be able to use the front panel on my pc and am communicating to the raspberry pi using the local I/O option.

You connect Agilent to your PC, and your PC talks to RPi over LINX and over VISA libraries or drivers with Agilent.

I follow what you’re saying and that’s exactly what I would like to do. However, I can’t get it to work with the raspberry pi. I can do that with Arduino, but I need 3.3V SPI so have to use raspberry pi. 

The only way I’ve been able to communicate with the raspberry pi is by using the Local I/O option which is by adding the raspberry pi as a real time device in my project. 

If you have time can you write up an example of what you’re suggesting? Thank you for the help so far.
