K 8055 --- programming by resistors?

Hi,

is there anyone who could explain to me what means programming by
resitor?

In the board are used 2 anal inputs for card adressing, why?
When I want to use 3 anal inputs why is it impossible?

Many thanks in advance!!!

Do you mean the two links at SK5 and SK6?

They are not inputs or resistors - they are just links that give the board a choice of 4 addresses: 0, 1, 2 and 3.

The fact that there are only 2 Analogue Inputs at A1 and A2 is just a design decision - there are no free pins on the microcontroller, so I think that to have more analogue inputs some other facility would have to be left out.
