STM32F4探索板hal閃爍不閃爍

[英]STM32F4 Discovery board hal blink not blinking

我剛開始在 stm32f4 發現板上玩 HAL。 最基本的眨眼不起作用,關於這件事的任何提示都會有幫助嗎? 代碼本身編譯沒有任何問題。

我正在測試 STM32CubeMX 並使用它預先生成的主文件。 內部沒有任何可能導致問題的高級內容。

我正在使用 CooCox CoIDE 開發環境。

您發布的代碼沒有任何明顯錯誤-大部分是由 stm32cubemx 生成的,對嗎?

嘗試檢查 stm32f4xx_it.c 文件的內部 - 您是否正在調用 HAL_IncTick(); 在 SysTick 中斷中? 沒有它, HAL_Delay 函數將無法工作......

另外,您是否嘗試過在調試模式下單步執行代碼以查看發生了什么? 至少這可能會告訴你你是否掛在任何地方。

如果以上都沒有幫助,那么我建議您刪除 MX_GPIO_Init 函數並編寫自己的函數來初始化要切換的 GPIO 引腳。

這是我使用 stm32cubmx 的主要問題——輸出過於復雜! 時鍾配置的東西很好,但我不希望在 main.c 中 - 在一個單獨的文件中就可以了(ish)...
