Hello all,
is it possible to shift 4 leds to left or right?
I do now with this code:

Rood Alias Portc.7 'LED
Blauw Alias Portc.6 'LED
Groen Alias Portc.5 'LED
Oranje Alias Portc.4 'LED

Config Portc.4 = Output 'Blauwe LED
Config Portc.5 = Output 'Rode LED
Config Portc.6 = Output 'Groene LED
Config Portc.7 = Output 'Oranje LED


Sub Leds
For X = 1 To 6
Toggle Groen
Waitms 125
Toggle Groen
Toggle Rood
Waitms 125
Toggle Rood
Toggle Blauw
Waitms 125
Toggle Blauw
Toggle Oranje
Waitms 125
Toggle Oranje
Next
End Sub

but is there an higher code level with shift or something?


(BASCOM-AVR version : 2.0.7.7 )

wow that looks complex for something simple Smile
ok i did not actually looked long at the code but try this instead:

Code:
do
  for x=4 to 7  'the leds
      set portc.x  'set led on
      waitms 125
      reset portc.x  'led off
  next
loop

Yes I understand the code but I think to difficult
when I see an example then it's easy.

A comment about the general principles here, not about this particular problem:

The aim of programming should be to get a computer to do the repetitive tasks we dont want to do. So we should avoid repetitive programming, let the computer do that !

This is a general problem in many 'high level' programming languages. In particular in languages which use objects, its almost mandatory to name the objects, and then have to treat them individually, by name. The concept of using a simple loop to access each object is almost forgotten.

I see the same in many posts where people have constructed a huge list of commands, or a very large select...case statement, to access a list of operations, where a simple loop through an array with an index would be far more efficient.
