Using Multy ATC(Analog to Digital Convertot)

Hello;
I am using two sensors to doing some measurement for me. And the out put should be shown to me on the LCD. When I use each of them separately , ADC works properly. but when I combine both sensors; the result is strange; although i set up the registers for using two ADC.
Can you guess where is the problem? why the answer of each sensor affect to another one?

I created the circuit for each sensor separately!
If more information or my code necessary; please let me know.
Thanks in advanced for your help.

Cheers;

Yes of course. Not sure it's going to be of much help, but I would guess that you have failed to head some critical piece of information in the documentation for whatever board/processor/adc it is you are using. I think it's a pretty good guess since you failed to head the advice in the sticky threads of this forum.

And since your query has nothing to do with C or the other languages covered in this forum, I will request this thread be moved to our Embedded Programming forum, where it belongs.
