ADC帮助代码配置器

我尝试在我的Explorer 16板上用PIC24FJ128GA310插件来执行ADC。我使用MPLAB X 3.30和代码配置器。我的目标是通过UART在屏幕上看到adc值。通过使用Code Configurator，我选择了引脚20（浏览器16板中的AN5-POT）和引脚25（AN0-adc的任何引脚）。此外，我使用UART1（PN49作为RX＆PAN50作为TX）。然后，我在main.c中生成代码&如下：int main(void){int转换；SYSTEM_Initialize()；ADC1_ChannelSelect(ADC1_POT)；.(1){ADC1_Start()；//Provide Delay ADC1_Stop()；.()！ADC1_IsConversionComplete()){ADC1_Tasks();}convertion=ADC1_ConversionResultGet();printf("Pot_value=%dnr",convertion);//Add您的应用程序代码//Add您的应用程序代码}.-1;}当我为adc选择POT(AN5)pin时，输出正好在第四位。船上电位器值的变化。但是，当我把ADC管脚换成AN0之类的其他管脚时，显示的输出接近3V。而且我用万用表检查了该管脚上面的万用表，它显示0.7V浮动。我需要一些建议在任何模拟输入管脚上运行adc。我需要改变一些硬件或软件的改变是否有效。

    I am trying to perform ADC on my explorer 16 board with PIC24FJ128GA310 plug in module. I am using MPLAB X 3.30 & code configurator.  My aim is to see the adc value on the screen via UART.

By using Code Configurator, I selected pin 20 (AN5-POT in explorer 16 board) & pin 25 (AN0- any pin for adc). Also I used UART1 (with pin49 as RX & pin50 as TX). Then i generated the code & in the main.c, i have done below:

int main(void)
{      int conversion;

       SYSTEM_Initialize();
      ADC1_ChannelSelect(ADC1_POT);
while (1)
   {

          ADC1_Start();
         //Provide Delay

          ADC1_Stop();
          while(!ADC1_IsConversionComplete())
                    {
          ADC1_Tasks();
                     }
           conversion = ADC1_ConversionResultGet();
          printf("Pot_value=%dnr",conversion);// Add your application code // Add your application code
    }
return -1;
}

When i am selecting POT(AN5) pin for adc, the output is coming exact the variation in on board potentiometer value. But when i am changing ADC pin to any other like AN0, the displayed output is near to 3 V. Also i checked by putting the multimeter over that pin & it was showing 0.7 V floating.

I need some suggestion to run adc on any analog input pin. Do i need to change some hardware or software changes will work.
