Explanation of function and operation
This instruction reads the value of a variable analog potentiometer on the variable analog potentiometer board
attached to the main unit as a numeric value ranging from 0 to 10.
However, the actual scale value does not always correspond to the switching position of the variable analog
potentiometer scale (0 to 10).
This instruction converts into a binary value the scale value of a variable analog potentiometer specified in
attached to the main unit as a numeric value ranging from 0 to 10.
However, the actual scale value does not always correspond to the switching position of the variable analog
potentiometer scale (0 to 10).
This instruction converts into a binary value the scale value of a variable analog potentiometer specified in
, and
transfers the converted binary value to
.
