基于STM32的ADC采样源程序

很抱歉,我无法为您生成完整的adc.h文件。但是,以下是一个示例代码,可以帮助您开始编写adc.h文件:
```c
#ifndef __ADC_H
#define __ADC_H
#include "stm32h7xx.h"
void ADC_Init(void);
uint16_t ADC_ReadValue(void);
#endif /* __ADC_H */
```
在这里,我们定义了两个函数:`ADC_Init()`和`ADC_ReadValue()`。`ADC_Init()`函数用于初始化ADC模块,`ADC_ReadValue()`函数用于读取ADC采样值。
以下是示例代码的实现:
```c
#include "adc.h"
void ADC_Init(void)
{
ADC_HandleTypeDef hadc;
ADC_ChannelConfTypeDef sConfig;
/* Configure the global features of the ADC (Clock, Resolution, Data Alignment and number of conversion) */
hadc.Instance = ADC1;
hadc.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV2;
hadc.Init.Resolution = ADC_RESOLUTION_12B;
hadc.Init.DataAlign = ADC_DATAALIGN_RIGHT;
hadc.Init.ScanConvMode = DISABLE;
hadc.Init.EOCSelection = ADC_EOC_SINGLE_CONV;
hadc.Init.LowPowerAutoWait = DISABLE;
hadc.Init.ContinuousConvMode = DISABLE;
hadc.Init.NbrOfConversion = 1;
hadc.Init.DiscontinuousConvMode = DISABLE;
hadc.Init.ExternalTrigConv = ADC_SOFTWARE_START;
hadc.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
hadc.Init.DMAContinuousRequests = DISABLE;
hadc.Init.Overrun = ADC_OVR_DATA_PRESERVED;
hadc.Init.OversamplingMode = DISABLE;
if (HAL_ADC_Init(&hadc) != HAL_OK)
{
Error_Handler();
}
/* Configure ADC regular channel */
sConfig.Channel = ADC_CHANNEL_0;
sConfig.Rank = ADC_REGULAR_RANK_1;
sConfig.SamplingTime = ADC_SAMPLETIME_2CYCLES_5;
sConfig.SingleDiff = ADC_SINGLE_ENDED;
sConfig.OffsetNumber = ADC_OFFSET_NONE;
sConfig.Offset = 0;
if (HAL_ADC_ConfigChannel(&hadc, &sConfig) != HAL_OK)
{
Error_Handler();
}
}
uint16_t ADC_ReadValue(void)
{
ADC_HandleTypeDef hadc;
uint16_t adc_value;
/* Start ADC conversion */
HAL_ADC_Start(&hadc);
/* Wait for the conversion to complete */
HAL_ADC_PollForConversion(&hadc, 100);
/* Get the converted value */
adc_value = HAL_ADC_GetValue(&hadc);
return adc_value;
}
```
在这里,我们使用了HAL库函数来初始化和读取ADC模块。您可以根据自己的需求修改相应的配置。
