MyOutput = %00011100_00110101

Hi all,
I have:

Leds 		PIN 	RBC OUTPUT		' LEDs on RB/RC

Setup into 6 groups leds, 2 lots of 2 leds and 4 lots of 3 leds.

I calculate the val of each group, i.e:

_

01 'group1

_---101-- 'group2

_001

'group3

00_

'group4
---111--_

'group5
000

_

'group6

How do I add them up to get:

MyOutput = %00011100_00110101

RBC = MyOutput

Is it like this:

' IO Pins

' -------------------------------------------------------------------------
' Variables
' -------------------------------------------------------------------------

group2            VAR     Word  ' 3 leds
group3            VAR     Word  ' 3 leds
group4            VAR     Word  ' 2 leds
group5            VAR     Word  ' 3 leds
group6            VAR     Word  ' 3 leds
MyOutput        VAR     Word

or is there a better way?

The 'Update_Output' should be:

SUB Update_Output
    MyOutput = group1
    MyOutput = group2 | MyOutput
    MyOutput = group3 | MyOutput
    MyOutput = group4 | MyOutput
    MyOutput = group5 | MyOutput
    MyOutput = group6 | MyOutput 

   RBC = MyOutput
ENDSUB

Yes?
or is there a better way?

I don't see where you set the groupX set variables to be anything.

It would help if you post a schematic of what you have the SX wired up to.

Would also help if you post the whole program.

Hi Zoot,
thank you for your time.
I have the SX wired up to 2 ULN2803As "Darlington transistor arrays",
that is one ULN2803A for RB0 - RB7 and one ULN2803A for RC0 - RC7.

I posted a schematic hoping for some input
THERE
but no input, so didn't bother posting the finished schematic with the ULN2803As in it.

That is the whole program so-far.

Regards SXlee.

Is that really the whole program? I don't see how it would compile and download to your SX. At the very least you declare subs that are undefined (and are called in the main part of the program).

SXlee · 2011-01-07 06:28

Yes, sorry Zoot.
My model in my head was:

Check_Inputs
Calculate_Groups
Update_Output

Now I think I only need:
Check_Input
Update_Output

I had a good idea of what I need for dealing with the input,
but couldn't see how to put info together for Updating the Outputs.

I think post #3 is OK
I need to do some moor on my SX28 Circuit.

Thanks for your time.

Regards SXlee.
