'

I want to sampling 250Hz'

I dont think you can sample the ADC that slow. If I am not wrong, the datasheet would tell you that you need to sample the ADCs faster than 50k sample rate.So you should probably set up the sampling faster but send your output to the UART only once every 250Hz if thats your application.

Thanks nazgul

Is there any difference between single adc mode(15cycle sampling) in while loop every 250Hz  and continuous mode faster than 50kHz?

I believe you will have accuracy issues if you sample slower than 50kHz.
