好的,以下是一段基于STM32的C语言ADC采集代码:
```c
#include "stm32f1xx_hal.h"
ADC_HandleTypeDef hadc1;
void ADC1_Init(void)
{
ADC_ChannelConfTypeDef sConfig = {0};
hadc1.Instance = ADC1;
hadc1.Init.ScanConvMode = ADC_SCAN_ENABLE;
hadc1.Init.ContinuousConvMode = ENABLE;
hadc1.Init.DiscontinuousConvMode = DISABLE;
hadc1.Init.ExternalTrigConv = ADC_SOFTWARE_START;
hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hadc1.Init.NbrOfConversion = 1;
if (HAL_ADC_Init(&hadc1) != HAL_OK)
{
Error_Handler();
}
sConfig.Channel = ADC_CHANNEL_0;
sConfig.Rank = ADC_REGULAR_RANK_1;
sConfig.SamplingTime = ADC_SAMPLETIME_239CYCLES_5;
if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK)
{
Error_Handler();
}
}
uint16_t ADC1_GetValue(void)
{
uint16_t adc_value = 0;
if (HAL_ADC_Start(&hadc1) == HAL_OK)
{
if (HAL_ADC_PollForConversion(&hadc1, 100) == HAL_OK)
{
adc_value = HAL_ADC_GetValue(&hadc1);
}
}
return adc_value;
}
```
这段代码初始化了ADC,并提供了获取单次采样值的函数。注:此代码只适用于单通道、单次转换模式的ADC采集应用。具体使用时还需根据实际需求进行修改和完善。
