i need to make the Microcontroller read an analog value that has range min=0.1 to .25 volt max.
I'm using AVR Microcontroller "ATmega32" , i know that the ADC in this uC has configure called "differential input" with "gain" option -that is what i understand from the datasheet in the table 26-4 page 276 and 277 from the datasheet in the A link or
attached picture kindly correct my information if I'm wrong-
- I ask if the gain for the differential channels is a solution to amplify the small range analog volt ? if not kindly list a solution.
- what is the effect of "reserved" if i used the configure ADC1 positive differential , ADC0 negative and gain 10x. the highlight config in the picture
in other word what is reserved mean here .
MUX[4:0]=01001
i read the answers of this question but it doesn't seem to be an answer to my second confused about reserved here?
