Altering a variable in a loop.

[HenrikOlsson]

Hi,
Several ways to do it, as usual. Here's one:

' Setting is your variable that step or down between 0-5
Lookup Setting, [12, 30, 55, 76, 98, 120], BaseDutyCycle

Another way would be to not step the Setting variable between 0 and 5 but to actually step it directly between dutycycle values

Select Case Step
  Case 12
    IF DOWN THEN
       Setting = 12 ' We're at the bottom setting
    ELSE
       Setting = 30
 
  Case 30
     IF DOWN THEN
        Setting = 12
    ELSE
       Setting = 55
    ENDIF

'And so on
  END SELECT

PWMDuty = Setting

/Henrik.
