STM32F446RE Nucleo Board の LED を点滅させようとしていました。オンボード LED は A ポートの 5 番目の PIN にあります。プログラムで次のエラーが発生し、ドライバー (gpio_drive.c) ファイルも含まれません。ここにエラーがあります。致命的なエラー: stm32f4xx_gpio_driver.c: そのようなファイルまたはディレクトリはありません
そして、それを削除してそのディレクトリなしでデバッグすると、次のエラーが発生します。
WWDG_IRQHandler() at startup_stm32f446retx.s:116 0x80002bc
Infinite_Loop: b Infinite_Loop .size Default_Handler, .-Default_Handler
メインコードは次のとおりです。
#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;
}
