Hi Linton,

I understand still not, what you mean with "prescaler". Thus I assumed it was a special hardware on your micro.


On all inputs e.g. from an ADC or pulse from external sensors you get a value X.
And then you must scale the value in this way "Y = a * X" with the scaling factor "a".
Now Y represent the real value e.g. temperature [°C].

But this is mathematics only, which can be done on every micro and very easy on programming in C.
