Blinky不工作的原因？如何解决？

问答对人有帮助，内容完整，我也想知道答案 0 我正在按照 st 的分步指南进行简单的 led 闪烁程序。在 GPIO_Init 函数中配置引脚后，LED 没有打开。我的代码有问题吗？我错过了部分引脚配置吗？任何帮助表示赞赏。如果我运行并调试该程序，它会在第 37 行停止。它只会在我单击 Resume 后继续。感觉像是一个断点，但没有。提前致谢。 /* Includes ------------------------------------------------------------------/ #include "main.h" / Private includes ----------------------------------------------------------/ / Private typedef -----------------------------------------------------------/ / Private define ------------------------------------------------------------/ #define HSEM_ID_0 (0U) / HW semaphore 0/ / Private macro -------------------------------------------------------------/ / Private variables ---------------------------------------------------------/ UART_HandleTypeDef huart3;

答案对人有帮助，有参考价值 0 如果您启用 GPIOB 和 E 时钟，除了其他时钟之外，考虑到您明确使用的时钟，可能会有所帮助。建议清除本地/自动变量以确保一致/可靠的行为
