Description
The function NORM norms a value of type WORD which lies
within the limits XH and HL to an output value within the limits
YH and YL.
This function is e.g. used for creating PWM values from analog
input values.
Example
not normed value:
50
bottom limit value input: 0
upper limit value input: 100
bottom limit value output: 0
upper limit value output: 2000
normed value:
1000
Due to rounding errors in hexadecimal figures a normed value
might deviate by 1. If the limits (XH/XL or YH/YL) are stated
invertedly the norming is also inverted.
