After lots of troubleshooting with [mention:acaf6a9338de4eef8f6717d5561ed01d:e9ed411860ed4f2ba0265705b8793d05] we got to the bottom of why Matlab didn't play nice with PST. It turns out that (at least my version of Matlab, which is not up-to-date), the Matlab defaults for line termination insertion are bad or are broken. The 'scan' feature in the instrument control toolbox might not work if you have an older buggy version of Matlab. It's not a big deal, since the workaround is to not do a scan (or to reboot the PST after a scan), or simply use a more recent release of Matlab.

The following code shows how to set outputs and read inputs, and works with older and current Matlab releases.

The visa object is deprecated and will be removed in a future release of Matlab; the newer visadev object is the replacement.

However, the code below should work with older releases as well as the current ones. I've added this example to the body of the blog too.

Has anyone found the LabVIEW Virtual Instrument Driver for a version other than 22? I have licenses for 2018 and 2020 and so If I install Community, it will mess up all my licenses. I tried Lynx, but was unable to get it to work.

To build the firmware with zero local tool installation on your own computer I made a git builder that posts the firmware on git after each commit. The "magic" is in this file: https://github.com/u77345/pico_scpi_usbtmc_labtool/blob/main/.github/workflows/main.yml

[mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05] , for this part of the documentation: Download the Pico SCPI labTool Project to your PC

It seems that CLion supports clone with submodules (see this forum post)

This would be needed when cloning the PST in its current incarnation

The next release (7) will bring a simplification: It 'll no longer be required to separately clone/download the SCPI-LIB. And the SCPI_LIB_PATH variable becomes obsolete.

The PST sources have become simpler in the last release (6). A lot of infra code, and the handling of standard usbtmc and scpi functionality are moved to a lib (PSL).
Soon, the SCPI lib, and the build commands for it, will be integrated into that PSL.

You write an excellent blog!

I finally got Visual Code up into running on Windows 10 for Pico. My main Windows 10 PC got too many different tools installed, which caused troubles for Windows environment configuration which required by Visual Code/Pico tool chain.

Time to play Pico SCPI labTool.

Thank you for sharing! I am looking forward to finding some time to try it out soon.

For those swimming in the deeper end of the pool, the Rhode Schwartz VISA tester can help to create standard compatible SCPI implementations: https://www.rohde-schwarz.com/fr/driver-pages/commande-a-distance/3-visa-and-tools_231388.html The tester tool royalty free and downloadable without an R&S account.

Very interesting post.

I just started playing around with a PICO, so if I get ambitious, I may try this approach.

For LabVIEW users (or learners), there's a Virtual Instrument driver for this instrument. It supports the same functionality as the current firmware: connect over VISA, control a GPIO output pin, release the connection
