Reminder: This article briefly reviews the relevant knowledge points of EXTI and NVIC, analyzing the external interrupt callback mechanism of the STM32F1 series microcontroller. Before we start, let’s review some knowledge related to EXTI and NVIC: External Interrupt/Event Controller (EXTI) For interconnect products (series 105, 107), the external interrupt/event controller consists of 20 edge detectors … Read more
Reminder: This article takes external interrupt for lighting as an example, analyzing the usage of interrupt service related functions in the HAL library, their interconnections, and underlying principles. 1. Example Implementation Example Overview: The main function controls LED2 to blink, while the interrupt controls the switch of LED0: First, we use CubeMX to create the … Read more
The development of STM32 microcontrollers relies heavily on their powerful library function support. These library functions provide developers with a unified interface, simplifying the operation of low-level hardware, improving development efficiency and the reliability of programs. Below we will share 20 commonly used library functions for STM32 microcontrollers. 1. GPIO Initialization Function void HAL_GPIO_Init(GPIO_TypeDef* GPIOx, … Read more
