Hi there,

I have been searching all day and kinda pulling my hair out in the process.

I have a simple program that pulls values from an Accelerometer. It works as expected.

I tried now to move all that to a library. Created a .h and .cpp files - checked my code and all falls apart.

Below is the build output: I am completely stumped.

Can someone tell me if: Adding new classes is supported, if returning an object (class defined) is supported from functions etc or any other pointers as to why this isnt working.

One other thing - If I remove all the code and go back to a blinking LED - I still get this build output and no uploaded program to the board.

Cheers for any help.

hi you can add new files in any way that you like. Think about how the arduino use works it does not have a project. The compiler in vs follows the arduino rules. This means that all sources in the sketch folder are always compiled so be sure to move unwanted sources out of the sketch folder or it will cause compilation errors.
