Hi,

The Start.c file includes some function used by all applications:

              - initialize the Stack Pointer,

              - initialize global variables,

              - copy ROM to RAM (if used in your application),

              - call the main function.

The entry of the application is defined by default as _Startup.

This function is defined in the start.c file included by default in the project.

This file contains different functions used by the startup function.

The best is to keep it safe.

Inside the file you will file lot of comments explaining it.

Have a great day,
Pascal
