ADC for unipolar input

I'm about to design an ADC for unipolar inputs(positive and negative) using an 80C552... A couple of questions: We know that Vref=(Vref+ - Vref-) If Vref+ = 2.5V and Vref- =-2.5V Then Vref=(2...

analog ADC input in logic analyzer

I'm using ADC in my project. I have scripts to change voltage on adc input pins. How can I see the values of adc input in logic analyzer. I'm trying AD0 , ain0 , bit it tells me "unknown signal"....

How can I assign an input pin?

Hi all, The machine cycle is too slow for me. Is there anyway to input a signal from signal generator into MCU, so I can use it to trigger? The pin assigns like: sbit dataIN = P1^3; How can...
