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
