Configuration files, driver files, and driver programs are very easy to confuse those who are just starting to learn the C language of microcontrollers. Today, I will use my own confusion to enlighten others.
Take LED dynamic scanning as an example to see what is in the configuration file:
# include
#ifndef __LED_DISPLAY_CFG_H
#define __LED_DISPLAY_CFG_H //If this file is not defined, define this file

# define __LED_DIN1_ON() p1^1=0
# define __LED_DIN1_OFF() p1^1=1
..........
...........
#define__LED-SEG(DATA) p0=DATA
#endif

In summary, the so-called configuration is to define the function of the I/O port.

Driver file:
The function of the driver is to tell the compiler the functions used, such as initializing the driver, outputting strings, clearing the screen, etc. Generally, the string array (font library) is placed in the driver code (driver program).
Driver program: Protect the driver file (header file), the executable C source file of the configuration file (uncompiled C file or assembly file)
