Hi Alain and others

Well I read a potmeter or other position encoder which is 10bit for full resolution
or equal to 1 single turn

Later I will convert this to Degrees (which is no problem)
But i would like to keep the maximum resolution to 10bit
but shift in the software the actual position instead of moving the potmeter mechanicaly

example

0 deg = 0V, 5V = to 360 (1024) or 10bit

imagine that the true 0 degree is at a value of 120 (decimal) and I dont want to move
the mechanical position of the potmeter but would like to see 0 as a decimal value
SO i would like to implement an offset of 120 decimal
whitout touching the 1024 10bit resolution for 1 revolution

I hope this is more clear
