STM32F429实现内部温度传感器【STM32F42X系列单片机_寄存器驱动】.zip
stm32f030是一款基于ARM Cortex-M0架构的微控制器,它内置有一个温度传感器,可以实现温度监测。下面是使用stm32f030内部温度传感器的代码实现步骤:
1. 使用HAL库函数初始化ADC模块,开启内部温度传感器;
2. 配置ADC采样时钟,设置采样通道为温度传感器;
3. 使用HAL库函数启动ADC转换;
4. 等待转换完成,读取ADC转换的值;
5. 根据ADC转换值计算温度值。
以下是示例代码:
#include "stm32f0xx_hal.h"
ADC_HandleTypeDef hadc;
uint16_t adc_value;
float temperature;
void MX_ADC_Init(void)
{
hadc.Instance = ADC1;
hadc.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4;
hadc.Init.Resolution = ADC_RESOLUTION_12B;
hadc.Init.ScanConvMode = DISABLE;
hadc.Init.ContinuousConvMode = DISABLE;
hadc.Init.DiscontinuousConvMode = DISABLE;
hadc.Init.NbrOfDiscConversion = 0;
hadc.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
hadc.Init.ExternalTrigConv = ADC_SOFTWARE_START;
hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hadc.Init.NbrOfConversion = 1;
hadc.Init.DMAContinuousRequests = DISABLE;
hadc.Init.EOCSelection = DISABLE;
hadc.Init.LowPowerAutoWait = DISABLE;
hadc.Init.Overrun = ADC_OVR_DATA_PRESERVED;
hadc.Init.OversamplingMode = DISABLE;
if (HAL_ADC_Init(&hadc) != HAL_OK)
{
Error_Handler();
}
ADC_ChannelConfTypeDef sConfig;
sConfig.Channel = ADC_CHANNEL_TEMPSENSOR;
sConfig.Rank = 1;
sConfig.SingleDiff = ADC_SINGLE_ENDED;
sConfig.SamplingTime = ADC_SAMPLETIME_239CYCLES_5;
sConfig.OffsetNumber = ADC_OFFSET_NONE;
sConfig.Offset = 0;
if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)
{
Error_Handler();
}
}
void get_temperature(void)
{
HAL_ADC_Start(&hadc);
if (HAL_ADC_PollForConversion(&hadc, 100) == HAL_OK)
{
adc_value = HAL_ADC_GetValue(&hadc);
temperature = (float)((110 - 30) / (float)(0xFFF)) * (float)(adc_value - 0xFFF * 30 / 110);
}
HAL_ADC_Stop(&hadc);
}
int main(void)
{
HAL_Init();
MX_ADC_Init();
while (1)
{
get_temperature();
printf("Temperature: %.1fC\n", temperature);
HAL_Delay(1000);
}
}
