About stm32f10x_conf.h in the peripheral V3.4 version is the use of instructions-EEWORLD

Collect

Let's talk about this question first. As we all know, when we choose which peripherals to use, we change lines 27-48 of the stm32f10x_conf.h file copied from the official template, include the header files of the peripherals we want to use, and comment out the header files of the peripherals we don't use. But have you noticed that we don't include the stm32f10x_conf.h file in the user main program file at all? So how do we modify this file to enter the main program file? There is only one answer. It is included in the file stm32f10x.h, because in the user main file, we use #include "stm32f10x.h" in the first sentence, so it should be that the stm32f10x.h file includes stm32f10x_conf.h, and is indirectly included in the user main program file. (In fact, if you look at the file structure diagram of the firmware library, you will understand that this is indeed the case. Our speculation is correct, see Figure 1 below)

Regarding stm32f10x_conf.h in the peripheral V3.4 version is the use of instructions - ╄→ wind, blow not scattered - ╄→ wind, blow not scattered

　　2. With the above understanding, we open stm32f10x_conf.h and search for "stm32f10x_conf.h". We see the following code in lines 8291-8293:
　　　　#ifdef USE_STDPERIPH_DRIVER
　　　　　　#include "stm32f10x_conf.h"
　　　　#endif
　　Do you see the problem? This conditional compilation means: if the USE_STDPERIPH_DRIVER tag is defined, then stm32f10x_conf.h is included, and if it is not defined, it is not included. Needless to say, we want to use the firmware library, so we should predefine the USE_STDPERIPH_DRIVER tag. KEIL provides a way to predefine tags before compiling, which is mentioned above in the project settings "option for target" => "C/C++" tab => "define" to add USE_STDPERIPH_DRIVER. As shown in Figure 2 below:

STM32F10x Study Notes 2 (SysTick Timer)

The SysTick timer is integrated into the NVIC. Therefore, any microcontroller with a Cortex-M3 core has it. This study note uses the SysTick timer to implement the revolving lantern function. The SysTick timer is very simple, with only four registers. The meaning of these four registers is very clear in the book "
