STM32F4发现板hal闪烁不闪烁

我刚开始在stm32f4探索板上玩HAL。 最基本的眨眼是不起作用的，关于这个问题的任何提示都会有帮助吗？ 代码本身编译没有任何问题

我在测试STM32CubeMX，并使用了它预先生成的主文件。 没有任何先进的内部可能是问题的原因

我正在使用CooCox CoIDE开发环境

您发布的代码没有明显的错误-大部分代码是由stm32cubemx生成的，对吗

尝试检查stm32f4xx_it.c文件的内部-是否调用HAL_IncTick（）；在SysTick中断中？如果没有这些，HAL_延迟函数将无法工作

另外，您是否尝试过在调试模式下单步遍历代码以查看发生了什么？至少这可能会告诉你你是否在任何地方被绞死

如果以上这些都没有帮助，那么我建议删除MX_GPIO_Init函数，编写自己的函数来初始化要切换的GPIO引脚

这是我使用stm32cubmx的主要问题-输出过于复杂！时钟配置的东西很好，但我不想在main.c中这样做-在一个单独的文件中就可以了（ish）

您已经定义了很多外围设备，请开始尝试删除所有不必要的部件，并从绿地开始，然后/或尝试调试它。在我看来，STM32CumeMX承诺的比它能承诺的更多。但我尝试的是，用cube生成的基本代码运行正常。我建议调试代码，并在时钟寄存器和IO端口寄存器中进行调查。我同意亚历克斯。。。检查HAL_IncTick（）
