... has a 'correction' formula - for the angle - the macro is still there - but using it gives a spiral effect - my maths isn't up to the job? Supplementary code holds the code to create a UART and receive data from the LiDAR (with a bigger buffer) - and to send commands. This data is then ...

Odd - the main directory should be created with the project - you could try either pasting the .h and .c files into the supplementary code (instead of the #includes) or give them a fixed address (#include "c:/test/file.h")

You could include an external .c and .h file if you didn't like being constrained to the supplementary code window and this way the AI can directly be in charge of the .c and .h files without a load of copying and pasting. Doing this way ...
