makefile:34: *** missing separator.

Thanks for this cool project!

I ordered this Pico Explorer Board and followed your instructions to build/make the .uf2-file. Unfortunately in the last step with "make" I have the following error

makefile:34: *** missing separator. Stop.````

What is in the generated Makefile around that line 34?

Building has only been tested on Linux, and it may generate different Makefiles on that...

Try "nmake" instead of "make"

And if that does not work either you can also try using CMake as "make" alternative with: "cmake --build . --target all"

cmake --build . --target all

And when using "nmake" ?

[maxnet]

And you do are using your own computer, and not a company computer that has been locked down?

It could be that it cannot find the resource compiler "rc" because it is not in the PATH. And one of the reasons for that could be that you did not had the right registry editing privileges, to add things to PATH when you installed Microsoft's development stuff.

(Or it could simply be that you have not installed the Win SDK)

I am working on my own PC and I am able to compile the PICO C projects under VS Code. Like these Examples from the book " Programming the Raspberry Pi Pico in C" or the original PICO-Examples. I will try to migrate your very cool projet in the same envirement and to build it under VS Code.
