STM32F4探索板hal閃爍不閃爍

我剛開始玩stm32f4發現板上的HAL。最基本的眨眼不起作用，任何關於此事的暗示都會有幫助？代碼本身編譯沒有任何問題。STM32F4探索板hal閃爍不閃爍

我正在測試STM32CubeMX並使用預生成的主文件來處理它。裏面沒有什麼先進的可能是問題的原因。

我正在使用CooCox CoIDE開發環境。

您沒有定義很多外設，請爲開始嘗試刪除所有不必要的部分，並開始在綠地和/或嘗試調試它。從我的角度來看，STM32CumeMX承諾的事情可能會超過它。但是，我嘗試使用多維數據集生成的基本代碼工作正常。 – vlk

您發佈的代碼沒有什麼明顯的錯誤 - 大部分是由stm32cubemx生成的，對吧？

嘗試檢查stm32f4xx_it.c文件的內部 - 你打電話給HAL_IncTick（）;在SysTick中斷內？沒有這一點，HAL_Delay功能將無法正常工作...

此外，你有沒有試過在調試模式下單步執行代碼，看看發生了什麼？至少可以告訴你是否掛在任何地方。

如果以上都沒有幫助，那麼我會推薦廢除MX_GPIO_Init函數並編寫自己的函數，它只是初始化要切換的GPIO引腳。

這是我對stm32cubmx的主要問題 - 輸出過於複雜！時鐘配置的東西是不錯，但我不希望在main.c中 - 在一個單獨的文件將是OK（ISH）...

我建議調試代碼並查看時鐘的寄存器和IO端口的寄存器。我同意Alex ...檢查HAL_IncTick（） – Lorenzo
