I've never tried to compile with Visual Studio so I can't help you, but the RP2040-tiny is functionally the same as the Pico and the RP2040, there is a huge amount of information out there on how to compile for them.

i am using the VS Code as code editor only, i compiled the project in terminal only using the cmake, but i am unable to find the uf2 file, how did you compile the project if not from Visual Studio? can you point me in right direction

You're using Visual Studio as compiler, or at least cmake seems to think so.

To be clear, you ran "cmake" in the build folder and got that output, did you then run "make"?

Maybe you need to open the .sln file in Visual Studio 17 and click build?

Or possibly delete the whole build folder, and run cmake again but specify a makefile output.

@mit can you please share the blender files to convert the shapes into header data files?
