If "Enable Update Interrupt" is not selected in the case mentioned above, the Update interrupt will not be generated, and consequently, the LED will not toggle since the update interrupt is disabled. When the sample time of the constant block connected to the timer block's UG (Update ...
This library enables you to use Interrupt from Hardware Timers on an STM32-based board, such as STM32F/L/H/G/WB/MP1.As Hardware Timers are rare, and very precious assets of any board, this library now enables you to use up to 16 ISR-based Timers, while consuming only 1 Hardware ...

其实是可能的。 前面说过,STM32 TIMER采样中心对齐计数模式的话,又分三种计数模式【具体解读见前文《一个基于TIMER事件的中断响应话题》】。如果TIMER采样中心对齐计数模式1,且CCR=0时,是不会发生比较事件的,自然不会有相应的中断响应发生。 有没有可能在当前计数周期内只发生2次中断响应呢?这里有两种情况: 第一...

STM32CubeMX 查看 timer10 频率 stm32频率检测 一、STM32 IO中断方式测试频率有要求,频率不能过快,目前测试2M没问题,频率过高中断触发就处理不过来。 二、过快的频率得先降频,用D触发器对频率进行降频,如下图所示,2、4、8、16分频,此例用2M时钟进行测试,对2M时钟进行2、4、8、16分频...
