Pi Pico SDK Install & Blink 🟥 Raspberry Pi Pico RP2040 C/C++ 

Nothing really. Most likely I will only duplicate what is already got on here if I decide to use another platform. Thanks sticking around for 3 years. I used to be somewhat active on twitter and patreon a few years back but it was mostly it was directing back to here. Links are in the description it you want to have a look.

If it is a link or a embed, go right ahead.

Sarcasm?

There is a link to my template files in the description.

@@BinderTronics thank you for your response. It compiled and made the correct .uf2 file which I flashed to my board. The blink example worked correctly. It just wouldn’t read the library via vs code for some reason. I have another question, since I echoed the path PICO_SDK_PATH to my C:\SDK can I install a library to any folder path there like my lib file and then reference that library in any folder in my C drive if the library is in the SDK folder? I found a one wire library I installed for a temperature sensor I purchased, DS18B20. One more question with that. Do I need to do anything different with my CMake files than what you showed if it is a single library I copied through git to my library folder?

k so you need to compile and link the lib to your project. This is done using the cmake files. You can have the lib anywhere on you system but it would be easier if it is in the same project folder. It is also easier if the lib is in a path that does not have spaces in it. Using GPT or some other LLM should get your going.

@@BinderTronics Thank you for responding again. I have since added the library to my dedicated library directory C:\SDK\pico-sdk\lib. I then created a folder labeled pico-onewire to a subdirectory where I store all my external libraries. I am adding it here instead of my project because it looks much cleaner for my project files. That said, I am having issues with the CMake files. This library has a source file "one_wire.cpp", and no matter what I have tried using GPT, it hasn't been able to find it. It always gives me the message "Cannot find source file: one_wire.cpp," followed by a list of other file extensions it tried without any luck finding it. My question is: How do I keep the library in that directory while calling it from my project? Everything is in my pico-sdk directory where I echoed PICO_SDK_PATH to.

is your main file still a .c file? you will need to change the file to .cpp and make your main function `extern "C" void main(void)`. You seem to be trying to use a main C file with a C++ lib. You can use C with C++ but not the other way around.
