But the ADC sample in this case cannot be higher than 4096.
the range is -2047 to 2048? Correct me if I'm wrong.
With this in mind, all you have to displaye on the LCD is some word
with constant length (like "Sample") and a 4 digit number with empty or '-' sign
as a prefix to the number, something like this:
- Sample: 0022 (this is an example of displayed positive sample)
- Sample: -1253 (this is an example of displayed negative sample)
Am I right?
