Web25 dec. 2024 · 用到了蜂鸣器、独立按键、LED、PWM输出捕获、引脚重映射、定时器中断等方面的知识。同时还要了解STM32内部时钟树,我用到的开发工具有:STM32 CubeMX和MDK kile5,并且我使用的是HAL库进行的编程。为什么不用标准库主要是因为,HAL库是ST公司一直维护和支持更... Web13 mrt. 2024 · 好的,我可以回答这个问题。. 以下是使用HAL库编写测量频率的代码示例:. 这个代码使用了 TIM2 定时器来测量频率。. 在主循环中,我们使用 __HAL_TIM_GET_COUNTER () 函数获取定时器的计数器值,然后计算出频率并打印出来。. 注意,这个代码使用了 printf 函数,需要 ...

Manually modify the hal program, add timer interrupt
WebSTM32F103, HAL and timer (s) I created a new project (using CubeMx & Atollic TrueStudio) for STM32F103RB and tried to toggle a bit as quick as possible; I use TIMER2 and this function to initialize it: sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNAL; The clocks & GPIO are correctly initialized (IMO). Web10 mei 2024 · htim2.Init.Prescaler = 71; htim2.Init.Period = 999; where the timer will count from 0: 999 in steps of 1uS. Your code has two problems, the timer frequency is too high … WebIn this STM32 Blue Pill tutorial, we will learn how to configure and handle timer interrupts using HAL Library in STM32Cube IDE. We will demonstrate this through an example by toggling an LED after a set number of time. Timer interrupts in STM32 pause the sequential execution of a program loop () function for a predefined number of seconds ... ferdinand ttte wiki
