I want to control the AD5254 Potentiometer parallel so that my maximum resistance is 2,5kOhm.
I am controlling the potentiometer with another potentiometer where i can regulate 5V, so it works in percent.. like
0V ........... 0% 2.5V ........... 50% 5V ........... 100%
The basic program is working with the Wire.h Library but i sadly have no idea how i control it, like when i have 42% or 63% .. how is the value (0-255 steps) calculated?
I would really be happy, if somebody can help me!
