我试图让我的 STM32F446RE Nucleo 板上的 LED 闪烁。板载 LED 位于端口 5th PIN 上。程序给了我以下错误，也不包括我的驱动程序（gpio_drive.c）文件。这是错误。致命错误：stm32f4xx_gpio_driver.c：没有这样的文件或目录
当我删除该目录并在没有该目录的情况下进行调试时，出现以下错误：
WWDG_IRQHandler() at startup_stm32f446retx.s:116 0x80002bc
Infinite_Loop: b Infinite_Loop .size Default_Handler, .-Default_Handler
这是主要代码：
#include "stm32f4xx_gpio_driver.h"
void delay(void){
for(uint32_t i = 0; i < 5000; i++);
}
int main(void){
GPIO_Handle_t GpioLed;
GpioLed.pGPIOx = GPIOA;
GpioLed.GPIO_PinConfig.GPIO_PinNumber = GPIO_PIN_NO_5;
GpioLed.GPIO_PinConfig.GPIO_PinSpeed = GPIO_SPEED_FAST;
GpioLed.GPIO_PinConfig.GPIO_PinMode = GPIO_MODE_OUT;
GpioLed.GPIO_PinConfig.GPIO_PinOPType = GPIO_OP_TYPE_PP;
GpioLed.GPIO_PinConfig.GPIO_PinPuPdControl =GPIO_NO_PUPD;
GPIO_PeriClockControl(GPIOA,ENABLE);
GPIO_Init(&GpioLed);
while(1){
GPIO_ToggleOutputPin(GPIOA,GPIO_PIN_NO_5);
delay();
}
return 0;
}
