ADC is always BUSY and Conversion does not complete

when i add a while loop to check the ADC mode is BUSY the control stays in this while loop 

I am trying to Read the Pin values using Adc_Readgroup

but to read successfully the conversion should be complete 

I am calling functions 

Adc_Calibrate(AdcGroup_0,&adc0_cal_status);

/* Setup the variables to contain the ADC results */
Adc_SetupResultBuffer(AdcGroup_0, &ADC_Group0Results[0]);

/* Initiate the initial conversion */
Adc_StartGroupConversion(AdcGroup_0);

before calling

Adc_ReadGroup(AdcGroup_0,&ADC_Group0Results[0]);

kindly find the configuration file below

Hi man,

Did you enable the Port Pin for ADC, and the Clock in MCU? Just hint for you.

Hi Vinhnguyen

             The problem is resolved the problem was I have two versions of the project there is no issue in the older version. When you replied i did checked the port pins and Mcu clock. the port pin was enabled and Mcu clock was set to SIRC. At later point of time when i was comparing the two versions i found that SIRC was not under Mcu control so i changed to SOSC clock now it works

           Your hint helped though but i was late to find it

Hi VinhNguyen

                 Thank You for the reply

                 Port pins are enabled in PORT and Clock(4Mhz SIRC) is enabled for ADC in MCU

Regards

Akbar
