SCPI on a Linux Board - Letter of Intent

Jan Cumps

I'm trying to build a SCPI shell for Linux.

I'd like to have it working over TCP/IP on a Raspberry Pi and a BeagleBone.

 

tl;dr It works. The rest of the blog series explains how to build a lab automation device that controls 8 outputs (2 of them relays), and read 8 inputs. With a Raspberry Pi and a PiFace Digital (2).

 

 

Here on element14, we've been playing with SCPI and microcontrollers. We have several instruments working on MSP432, Arduino and Hercules devices.

This time I'd like to get a Linux instrument up. To get some device independence, I'll try to make the source work on two different boards with different distros.

The program is expected to run as a background process.

 

I have a head start. My favourite SCPI library has a LwIP SCPI server example.

A relative head start, that is, because I have to find out how to get all the dependencies - I want to develop on a Windows PC .

If this project fails, it'll be because of my develop for Linux skills.

  • Inspired by the BeagleBone Webcast series, I'm picking up this thread again (I have a few running in parallel these days )

     

    I've installed the latest Debian on my BB and have just successfully cross-compiled and loaded a test program.

    Here's an action shot of the active debug session:

     

    For this exercise, there should be no difference between the Raspberry Pi and BeagleBone for the SCPI library and network socket API.

    It's only when talking to hardware that things will be different, but that's not the scope of this series.
