1. void GPIO_DeInit(GPIO_TypeDef* GPIOx); First, let’s take a look at this function. We can see that the parameter of this function is a GPIO group parameter (GPIOB, GPIOC, GPIOA, etc.),Now, let’s enter the definition of this function in the standard peripheral library. void GPIO_DeInit(GPIO_TypeDef* GPIOx){ /* Check the parameters */ assert_param(IS_GPIO_ALL_PERIPH(GPIOx)); if (GPIOx == GPIOA) … Read more
“ Developers who are new to microcontroller (MCU) development often find themselves confused: should they manipulate registers directly or use library functions? This is akin to choosing between manual and automatic transmission — the former offers precision but is complex, while the latter is simple but lacks a sense of control. This article uses STM32 … Read more

STM8 microcontroller has multiple timers, among which TIM1 is a high-performance timer (16-bit), with the most powerful functionality. There are a total of 46 library functions related to it, covering function types that generally apply to other timers, with a few being unique to it. All functions are presented in parts, and this is the … Read more
C Language Function Review Overview In the first chapter, it has been introduced that C source programs are composed of functions. Although the previous chapters’ programs only have one main function main(), practical programs often consist of multiple functions. Functions are the basic modules of C source programs, and specific functions are implemented through the … Read more
Continuing from the last time! Last time we discussed break and continue, leaving two pieces of code! The result of the first piece: 01234 Explanation: When i++ reaches 5, break is executed, and the code exits the loop, ending! The result of the second piece: 12346789 Explanation: When i++ reaches 5, continue is executed, the … Read more
Intermediate PLC Programming: Custom Library Function Development for Easier Reuse of General Functions! 🔥 Pain Points of Traditional PLC Programming: The Vicious Cycle of Duplicate Code Does your PLC program frequently contain duplicate code? Does modifying one function cause a ripple effect throughout the entire program? Is it like searching for a needle in a … Read more
1 Introduction to Linux Library Functions Linux provides a rich set of library functions that cover various domains, from file operations to network programming, graphical interfaces, mathematical operations, and more. Most of these library functions are standard C library functions, along with some that are specific to the Linux system. Linux library functions are typically … Read more
