For most of the applicative examples provided, more than one timer feature is used to carry out a well-defined application usage. However each example also puts more focus on a particular feature of the STM32 general-purpose-timer peripherals. For all the details on the general-purpose timers...
如果你只有C语言基础，你有上面这些疑惑，是非常非常正常的。因为C语言只是一门编程语言，在单片机上，你...
一. TIMER分类:STM32中一共有11个定时器,其中TIM6、TIM7是基本定时器;TIM2、TIM3、TIM4、TIM5是通用定时器;TIM1和TIM8是高级定时器,以及2个看门狗定时器和...,其脉冲宽度则为比较寄存器TIMx_CCR的值A乘以触发脉冲的时钟周期,即输出PWM的占空比为 A/(N+1) 。三、STM32产生PWM的配置方法:1、配置GPIO口...

In this Blue Pill tutorial, we will discuss how to configure STM32 timer module in encoder mode. We will use a rotary encoder to demonstrate that how to read the encoder ticks using STM32Cube IDE and HAL libraries. In the first example, we will display encoder ticks on a serial terminal...
In addition to measuring execution time, we can recreate the blinky example using timers. By doing so, we can create non-blocking code to toggle the LED. This allows you to run other code while waiting for the LED to toggle. Back in the CubeMX perspective, change the ...
you canusethe count flaginthe SysTick Control and StatusRegister(SysTick->CTRL) to determine when the timer reaches zero. For example, you can create a timed delay by setting the SysTick timer to a certain value and waiting until it reaches zero: ...
