【ST NUCLEO-U5A5ZJ-Q开发板测评】5 程序中加入ADC [复制链接]

         【ST NUCLEO-U5A5ZJ-Q开发板测评】5 程序中加入ADC
 
 
ADC的作用自然是明显的，模拟的数据采集很需要它，这里我们用PC2那个ADC接口实验，因为它连接到了一个零点几伏的电源。
 
一、检查一下原理图：
 
二、使用stm32cubuide开启adc 如果有需要可以用同样方法开启PC0 PC1采集数据。
 
三、保存生成代码
 
四、加入开启电源的函数。
 
五、开启浮点
 
六、定时中断中设置标志，实现主程序中定时采集：
 
七、主程序中加入采集代码，并送串口一显示。
 if(adc2_tim >=10)
       {
    	   adc2_tim=0;
    	   char uart_buf[300]={0};
    	   HAL_ADC_Start(&hadc1);
    	   uint32_t adc2_val = HAL_ADC_GetValue(&hadc1);
           sprintf(uart_buf,"vdd is %6d, folat display is :%f\n",(const int)adc2_val,(float)adc2_val*3.3/16384);
    	   HAL_UART_Transmit_IT(&huart1,(const uint8_t*)&uart_buf[0], 50);

       }

 

八、整体代码

九、编译下载测试，先不查type C接口，后面再插观察数据变化。
