STM32CubeMX配置STM32G031多通道ADC采集（HAL库开发）

时钟配置HSI主频配置64M

勾选打开8个通道的ADC

使能连续转换模式

配置好串口，选择异步模式配置好需要的开发环境并获取代码

修改main.c

串口重定向

#include "stdio.h"
int fputc(int ch, FILE *f)
{HAL_UART_Transmit(&huart1, (uint8_t *)&ch, 1, 0xFFFF);return ch;
}

串口重定向一定要勾选Use Micro LIB

获取ADC通道值

uint32_t ADC_Get_Average(uint8_t ch)
{ADC_ChannelConfTypeDef sConfig;uint32_t value_sum=0;	switch(ch)							{case 0:sConfig.Channel = ADC_CHANNEL_0;break;	case 1:sConfig.Channel = ADC_CHANNEL_1;break;case 2:sConfig.Channel = ADC_CHANNEL_2;break;case 3:sConfig.Channel = ADC_CHANNEL_3;break;case 4:sConfig.Channel = ADC_CHANNEL_4;break;case 5:sConfig.Channel = ADC_CHANNEL_5;break;case 6:sConfig.Channel = ADC_CHANNEL_6;break;case 7:sConfig.Channel = ADC_CHANNEL_7;break;}sConfig.SamplingTime = ADC_SAMPLINGTIME_COMMON_1;		sConfig.Rank = ADC_REGULAR_RANK_1;HAL_ADC_ConfigChannel(&hadc1,&sConfig);											HAL_ADC_Start(&hadc1);								HAL_ADC_PollForConversion(&hadc1,30);				value_sum = HAL_ADC_GetValue(&hadc1);								HAL_ADC_Stop(&hadc1);								return value_sum;									
}

主函数

int main(void)
{HAL_Init();SystemClock_Config();MX_GPIO_Init();MX_ADC1_Init();MX_USART1_UART_Init();uint16_t i = 0;uint16_t Adc_Val = 0;static uint16_t count = 0;while (1){count++;if(count % 100000 == 0){for(i = 0; i < 8; i++){Adc_Val  = ADC_Get_Average(i);printf("CHANNEL%d = %04d, %f V\r\n", i, Adc_Val, (double)Adc_Val / 4095 * 3.3); }printf("\r\n\r\n\r\n\r\n\r\n"); }}
}
