Question

我已经尝试了一切，在这里真是茫然。

问题陈述：该代码不会进入while循环。

1。使用STM32F303C8。

2。我有三个板块：

Nucleo F303RE
Nucleo F303K8
Custom board.

所有芯片都具有相同的IC，并且存在相同的问题。因此，问题必须与软件有关。

我已将整个代码和cubeMX文件发布到BitBucket上。请在此处找到链接：Link for CubeMx Software TrueStudio Project

代码只是拒绝进入while循环。
如果删除了IWDG初始化函数，则代码将停留在序列中最后一个初始化函数调用处。如果对IWDG进行了注释，它会跳回到代码的开始并执行直到while循环的开始。
可能是启动文件吗？

谢谢您的支持。

Answer 1

我能够解决问题。相当愚蠢，但对于刚开始使用HAL的人们可能会有帮助。正如old_timer的答复一样，该问题确实与时基有关。

根本原因：计时器6已初始化，但是它的计时器基础需要单独初始化。解决方案：调用函数MX_TIM6_Init之后，集成函数HAL_TIM_Base_Start_IT(&htim6)。这样就解决了问题。另请注意，由于我在中断模式下使用TImer 6，因此需要HAL_TIM_Base_Start_IT函数。否则，您应该调用HAL_TIM_Base_Start函数。

问候，
