Hi all,

I fed 2V and 1V DC signals to ADCIN0 and ADCIN1 respectively and ran my program in F2812 DSP,
it didn't work as i have expected. The thing is I observed ADCRESULT0 as 0XFFF0 and ADCRESULT1
as 0xFFF0 in watch window.I have given ADC VREFLO to gnd and the two ADC inputs gnd to the
analog ground. Moreover, I have also observed the equivalent voltage after the conversion of
digital input by 3/4095, it was 3.00789e-06. Its very strange.

My doubt is 

1)why it didn't indicate the exact digital value of 2V and 1V in the respective result
registers.

2) why  it shows 0.00789e-06 for 
x[Conversioncount]=(ADCRESULT0>>4);
x1[ConversionCount]=x[ConversionCount]*(3/4095); even if it shows wrongly as 0xFFF0 in result
registers, the x1 value would be 3V, but i have got 0.00789e-06.

Can any one extend your helping hand?

Many thanks in advance
