stm32控制直流无刷电机（带霍尔传感器）的程序，不能进入定时器1触发中断，求指教

krnfx

问下用stm32控制直流无刷电机的程序，这里用定时器2的3个通道捕获霍尔传感器的信号，用定时器1发生6路PWM,然后让定时器2触发定时器1，定时器2为主模式，定时器1为从模式，在定时器1触发中断里发生换相，但是在板子上电机从来没有转过，下面是配置，希望各位高手指点

帮顶。。。。

好高深，帮顶，我也想学这个，可是没机会

为什么要用定时器检查霍尔呢
用外部中断检查不会更好吗

comprends

楼主可以讲下，这个程序的思路吗，不知道该怎么写，现在要做一个基于STM32的无位置传感器的无刷直流电机的控制，用反电动势测量位置，不知道整个程序该怎么写，大概的框架是怎么样的，求解

我用输入捕获采集霍尔元件信号，1Khz的频率都很准确

pyh

用外部中断触发可以转动

向上吧STM32

你好，请问你提出的这个问题解决了吗？

向上吧STM32

麻烦问你一下不能进入中断的问题解决了吗

向上吧STM32

定时器中断抢占优先级降低一些。

吖基哈
