Hi,

what about the relationship between Kp, Ki, Kd and the width of the input signals? For example if i have input data coming from a 12bit ADC with 5V analog range and a 12bit ADC with 2.5V analog range (so the same input voltage is rapresented with different words) are the PI parameters affected by this?
