完整写出stm32F401温度adc采集 hal库

以下是stm32F401温度adc采集 hal库的完整代码：

#include "stm32f4xx_hal.h"

    temperature = ((float)adc_value * 3.3 / 4096.0 - 0.76) / 0.0025 + 25.0;

    HAL_Delay(1000);
  }
}

void SystemClock_Config(void)

}

void Error_Handler(void)

  while (1)
  {
  }
}

这段代码初始化了ADC1和温度传感器，然后在while循环中读取ADC值并将其转换为温度值，最后使用HAL_Delay函数延迟1秒钟。请注意，此代码仅适用于stm32F401芯片。
