Hi. Another question in my quest to learn. I am using an ADS1114 16 bit a/d converter and the Adafruit ADS1115 library https://github.com/adafruit/Adafruit_ADS1X15 although I suppose this is common with many ADC's. My sensor has a total output from 0.3v to 1.4v so only approx 1v full scale. The ads1114 is giving me approximately -6000 to 6000 as an output which is about right I guess, 12000 counts for a 1v input.
My question is how do convert the input into a positive ONLY value in the most efficient way for processing time. I know i could just add 7000 to the value and always have it positive but I am sure there is a more efficient way done by the pro's?
