Hi, i would like to ask about a certain problem occuring with me during the adc conversion..instead of converting 4v for example to the right binary number at the output..i'm always getting an answer at the output less than arounf 0.5v from the real voltage at the input..what's the solution?
No one can make make a qualified judgement without seeing both your source code and full circuit diagram, you do not even mention the micro or programming code you are using.
Please post them so we can look into your problem more.
hi all, in my project i'm using different types of sensors on a multiplexer and they're all going through adc conversion. if the output of one sensor is 4v for example, the microcontroller sends 3.5v after converting it to digital..there's always this gap in the voltage...should i place any voltage buffer after each sensor to prevent this drop down or what?
yes i'm only interested in the highest 8 bits and i want to neglect the least 2 signigicant bits since the encoder connected to the microcontroller can only read 8 data bits and not 10
