Method 1:manual measurement
• Increase the analog input to the ADC slowly until we can make the digital output 1
LSB more,from 11010 to 11011
• write down the correspond analog input value V1
• decrease the analog input to the ADC slowly until we can make the digital output
return to the 11010
• write down the correspond analog input value V2
• The transition point between 11010 and 11011 is 0.5(V1+V2)
Code 11011
