Hey guys im not a noob when it comes to takin in samples from ADC but i wanted to know... can we use ADC to calc battery voltage like...
Lets say my battery is a 3.6v and it drops to 3v...
How do i still use that 3.6v from before ? Like if i use my main power *Battery* as the VREF then it will always show 100% since its the refrence... How to i check level against power that isnt there?
Anyway the basic question is how to use ADC for battery monitor?
