Just noticed today that every Pi pinout diagram is vertical! For the times a more horizontal approach is preferred:

Slightly more printer-friendly version:

Slightly frustrated with setting the PICO_SDK_PATH as a local reference "../../pico-sdk." In Windows Environment Paths, set the PATH to your full location (for me: "c:/users/sjham/pico/pico-sdk/") and in CMake Tools in VSCode set all paths likewise. No more ../../ nonsense that breaks when you create a separate folder alongside the sdk and examples for your own development.

Hello,

Please, I am a new programmer under VS Code.

On a windows 10 computer (Spanish) I was able to compile manually all the examples but I tried the code generator with new projects under VSC (Windows 64) and I always got errors, when I compiled the example provided in the .zip file of this web page.

I tried the Raspberry Pi environment configuration from this documents and a PDF instructions from RASPBBERRY Pi foundation and it failure in compile the example provided in the .zip file.

I received always error. The error is "C1083: Cannot open file include: 'pico/stdlib.h': No such file or directory".

Please, any suggestions .

Thanks

Hi,

I did the manual compilation of PICO examples without any problem.

I did all the steps under Visual Studio Code but when I compiled the PICO EXAMPLES, I got the followings errors.

Please, can anybody provide a suggestion?

Thanks

RE: Working with the Raspberry Pi Pico with Windows and C/C++

I finally managed to find the time to write up the process of getting debugging working with the Pico, VS Code, and Windows. Rather than repeating things, my guide builds on Shabaz's work and starts where this one stops.

Debugging the Raspberry Pi Pico on Windows 10

RE: Working with the Raspberry Pi Pico with Windows and C/C++

Fred27 — Wed, 03 Feb 2021 21:19:22 GMT

Good news! I eventually managed to get a reasonable debugging experience using Windows 10, Visual Studio Code and a "picoprobe" debugger. I gave up on using a Segger JLink or a TI XDS110 for now and bit the (not too expensive) bullet of the second Pico as the debugger.

I'll write it all up once I've gone back over my tracks and worked out exactly what was needed and remove the dead ends.

Fred27 — Sun, 31 Jan 2021 17:53:30 GMT

They've definitely focused their attention on developing using a Pi as your development environment - and why wouldn't they. I'm sure the Windows, Apple, and Linux desktop stuff will get easier with time. Right now I'm certainly making better progress and learning more by starting on a Pi 4. I've only got one Pico so the picoprobe stuff is out for now. Using the Pi's gpio for SWD will at least show me how the debugger experience should look before I try to get it working under Windows. During my previous experience using C IDEs for microcontrollers, I happily let the manufacturer hide the complexity of gdb and openocd from me.

I was just about to make some suggestions for our recent poster - despite him being a little demanding and unappreciative of the helpful responses so far. However, it seems he's deleted his posts. Very odd. (I've scattered some "helpfuls" on his behalf.)

FWIW, I was going to suggest that if you want tried and tested solutions then a brand new microcontroller from a manufacturer who's new to that field might not be the best way to go. If Bluetooth is important then established devices like the Nordic nRF52840 would be a good fit. The Pico seems nice, but right now it's for those of us who like to tinker and learn about new stuff.

Did you use a 3.3 V compatible LCD display?

If you are having an issue with an example from the pico-examples, then open an issue at the GitHub repo. That is how it usually works.

Have you looked at the pico-examples?

You may need to refactor your search.

Well, I intended to wait until all the usual "new Pi" fuss had died down, stock levels were normal everywhere, etc. Then I happened to pop into W.H.Smiths and there it was sitting on the front of Hackspace magazine... so I bit. [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-879d5474-e397-410f-9e3f-7f59bae5d8a5/contentimage_5F00_734.png:16:16]

I must admit that getting to this point wasn't too hard. The getting started guide provided was fine, but it was good to have Shabaz's more detailed guide to fall back on. Thanks. One thing worth mentioning is that a few people seem to be using "Visual Studio" and "Visual Studio Code" interchangeably. Whilst they are both Microsoft IDEs and share some similarities, they are very different products. Visual Studio is a "full" Windows-only IDE for Microsoft development tools. Visual Studio Code is more lightweight, cross-platform and a bit more extensible - sort of like the new Eclipse.

I must admit I don't consider an IDE completely working until you can hit a breakpoint and check variables (hence why I never liked the Arduino). I'll dig into this later and hopefully will be able to add to the guide so that we can debug properly from within Visual Studio Code on Windows. However, I'm now due some beers with a few friends - over video of course - so that will have to wait until tomorrow.

Hi shabaz,

Great, that worked!

Incidentally, I also learned quite a bit about how to structure a native C/C++ program!

Thanks very much for that!!

Hi shabaz,

Thanks for the extra information on intellisense and the instructions on how to create a new project, independently of the pico examples.

It will be very helpful!
