Regular readers will know that I’m a big proponent of PlatformIO as a programming platform for the ESP family; it’s just so much better than the Arduino IDE for us command-line interface die-hards. As I’ve noted before, I’m not a religious fanatic on the CLI vs GUI thing; it’s just that GUIs (with a couple of exceptions) don’t really click for me. Most of the time I just don’t “get it” and what’s on offer usually seems to limit the functionality without really adding much, if anything, in ease of use. Recently though, I’ve been searching for information on getting started with the ESP32’s built-in version of FreeRTOS (specifically, looking for more information on real-world use, rather than just a couple of sentences about the syntax of the xTaskCreate() call) and I found a couple of very useful videos by Xavier on his “Simply Explained” channel which, as the name suggests, do a very good job of explaining by example, how to use FreeRTOS. The thing which (as a doddering old git) really caught my attention was his use of Visual Studio Code. I was captivated by the pop-up prompt with info on the parameters (of which there are plenty) to feed to xTaskCreate. While I imagine that functionality can get pretty tedious when it pops up for each and every printf(), it does look like a definite winner when you’re learning something new (and don’t have much in the way of short-term memory any more).
Now, what was I saying again? Oh yes, here’s the link to one of Xavier’s videos. He’s got a ton of content on his channel on many diverse (but usually tech-related) topics. This one is not the first in the series, so if the abrupt lead-in is a bit too much you can go to his Intro on FreeRTOS instead. I highly recommend watching Xavier’s videos if you’re trying to get started with FreeRTOS.
Of course, I immediately went off and downloaded Visual Studio Code and fired it up …only to just as immediately get totally lost when I couldn’t get it to do anything that I wanted. I did watch a few more videos from a nice lady at Microsoft, but ended up suffering from information overload and Windows-itis. I went for a nice cup of tea instead. And then went back to PlatformIO in an xterm, just so that I could get something done.
More recently, one of my regular morning reads, Hackaday, had an article on making laminated artwork for front panels with an accompanying video (worth a look in itself) by Richard Langner. I was impressed by Richard’s succinct, no-nonsense style and dipped into his video listings to see what other goodies were there. Lo and behold, right at the top of the list were a couple of videos on how to get started with Visual Studio Code with PlatformIO. The first was only a minute and a half long and the second just over six minutes. Both are filled with essential information on doing just what I wanted to do (have the editor prompt me with useful info, but still be able to use PlatformIO as my programming environment). As they’re so short, I’m including both as embedded links below. Take a look. Even if you don’t like them, you won’t have wasted much time.
Many thanks to both Richard and Xavier (oh, and Al Williams and the team at Hackaday, as well as Ivan and everyone at PlatformIO) for making my life not just easier, but a lot more interesting, too.
