Split code into multiple codes?!

Projects Programming
1

I now have quite a long code for my carrier OS. So that this is clearer, I would like to split it up into several parts, i.e. files. Is the? How do I do that?
I have an MKR IoT Carrier Rev2 and MKR WiFi 1010 board.
Many, many thanks in advance!

Move each of your functions into a new file (in the project folder).
Write a header file declaring all these functions and other common items (libraries, variables, constants...).
#include that header file wherever required.

Just had that discussion in This Thread.

For a basic guide, see My Post #5 in this Thread.

Thanks, but I would have meant if there is someone who could do it specifically on my code.... Otherwise it fits too!

don't think putting each function into a separate file.

it makes sense to organize code supporting some function into the same file. for example, i'm working on a program that has i2c.cpp, wifi.cpp, pcRead.cpp (cli commands), signals.cpp (RR signal code) and sigMap.cpp (tables defining signals and blocks with no code).

.h files provide forward declarations for the public functions in each file

Wrong category! Post in "Jobs and Paid Consultancy".

Otherwise begin yourself and come back in case of problems.
