Help wanted. How can I change variables with s

Archiver

Kai-

Here's one approach. Use pulldown resistors (~47 KOhms) on
each of I/O 0, I/O 1, I/O 2, I/O 3, then a switch on each to
+5 Volts. Set switches for desired value with code like:

a = IN0 + ( 2*IN1 ) + ( 3*IN2 ) + ( 4*IN3 )
FOR level = 0 TO 255 Step a 'a is the variable I will change
PWM Pin1,level,25
gosub delay
NEXT

Or, to save variable ("a" not used) and code space:

FOR level = 0 TO 255 Step ( IN0 + ( 2*IN1 ) + ( 3*IN2 ) + ( 4*IN3 ) )
PWM Pin1,level,25
gosub delay
NEXT

Steve
