一、配置步骤：

1、用cubemx配置底层；

2、cubemx配置好的文件替换之前的配置文件；

3、修改Kconfig文件，添加adc配置选项；

4、用env配置工程，打开adc；

5、打开mdk工程，打开adc功能配置选项宏定义；

6、添加测试函数；

7、测试展示；

二、用cubemx配置底层:

三、cubemx配置好的文件替换之前的配置文件：

四、修改Kconfig文件，添加adc配置选项：

menu "On-chip Peripheral Drivers"

**********  其他  ***********



    menuconfig BSP_USING_ADC
        bool "Enable ADC"
        default n
        select RT_USING_ADC
        if BSP_USING_ADC
            config BSP_USING_ADC1
                bool "Enable ADC1"
                default n
        endif



**********  其他  ***********

endmenu

五、用env工具配置：

六、打开mdk工程，打开adc功能配置选项宏定义：

七、添加测试代码，配置debug：

adc测试代码：

#define ADC_DEV_CHANNEL     1           
#define REFER_VOLTAGE       330         
#define CONVERT_BITS        (1 << 12)   

static int test_adc(void)
{
	rt_adc_device_t adc_dev;
	rt_uint32_t value, vol;
	rt_err_t ret = RT_EOK;
	rt_uint8_t count =0;
	
	
	
	adc_dev = (rt_adc_device_t)rt_device_find(ADC_DEV_NAME);
	if(adc_dev == RT_NULL)
	{

		return RT_ERROR;
	}
	
	
	ret  = rt_adc_enable(adc_dev, ADC_DEV_CHANNEL);
	
	while(count <10)

		rt_kprintf("the value is :%d \n", value);

		
		vol = value * REFER_VOLTAGE / CONVERT_BITS;
		rt_kprintf("the voltage is :%d.%02d \n", vol / 100, vol % 100);		
		
		rt_thread_mdelay(500);
	}
	
}

MSH_CMD_EXPORT(test_adc, function test adc);

整个main.c文件：

#include <board.h>

    int count = 1;
		
    while (count++)
    {
			rt_thread_mdelay(100);
    }

    return RT_EOK;
}

		rt_kprintf("引脚输出底电平\r\n");
		rt_thread_mdelay(500);
	}
}
