··· I wrote this code to turn on and off 2 groups of outputs.· On for 3 seconds and off for 5 seconds, etc.

Then due to hardware logic changes I just want to invert the outputs.· So I made the following modification.

PUB timer
· dira[noparse][[/noparse]1..5]~~
· outa[noparse][[/noparse]1..5]:=1

· repeat
··· !outa[noparse][[/noparse]1..2]
··· waitcnt(clkfreq *3· + cnt)
··· !outa[noparse][[/noparse]1..2]
··· waitcnt(clkfreq *5 + cnt)
··· !outa[noparse][[/noparse]3..5]
··· waitcnt(clkfreq *3· + cnt)
··· !outa[noparse][[/noparse]3..5]
··· waitcnt(clkfreq*5 + cnt)

Only the outputs 3..5 were reversed.··Output 1..2 were not.··Can you tell me what I am doing wrong?

Hi Jgonzo,

I hope I've interpreted your requirements correctly, here is my version of your code...

I've added some comments to the code to explain what is happening,

Your first routine converted thus:-

All pins start low (~) Pins 1..2 High (~~) for 3 Seconds, all pins low for 5 seconds, Pins 3..5 High for 3 Seconds, all pins low for 5 seconds, repeat ad infinitum.

PUB timer
  dira[noparse][[/noparse]1..5]~~                   ' Make pins outputs
  outa[noparse][[/noparse]1..5]~                    ' Pins Low
 
  repeat                         ' Repeat Forever
    outa[noparse][[/noparse]1..2]~~                 ' Pins 1..2 High
    waitcnt(clkfreq *3  + cnt)   ' 3 Second Delay
    outa[noparse][[/noparse]1..2]~                  ' Pins 1..2 Low
    waitcnt(clkfreq *5 + cnt)    ' 5 Second Delay
    outa[noparse][[/noparse]3..5]~~                 ' Pins 3..5 High
    waitcnt(clkfreq *3  + cnt)   ' 3 Second Delay
    outa[noparse][[/noparse]3..5]~                  ' Pins 3..5 Low
    waitcnt(clkfreq*5 + cnt)     ' 5 Second Delay

Your second routine:-

Pins 1..2 start low (~) and Pins 3..5 start high (~~), Pins 1..2 High for 3 Seconds, Pins 1..2 low and Pins 3..5 remain high for 5 seconds , Pins 3..5 Low for 3 Seconds, Pins 1..2 remain low and Pins 3..5 high for 5 seconds, repeat ad infinitum.

PUB timer
  dira[noparse][[/noparse]1..5]~~                   ' Make pins outputs
  outa[noparse][[/noparse]1..2]~                    ' Pins 1..2 Low
  outa[noparse][[/noparse]3..5]~~                   ' Pins 3..5 High
  
  repeat                         ' Repeat Forever
    outa[noparse][[/noparse]1..2]~~                 ' Pins 1..2 High
    waitcnt(clkfreq *3  + cnt)   ' 3 Second Delay
    outa[noparse][[/noparse]1..2]~                  ' Pins 1..2 Low
    waitcnt(clkfreq *5 + cnt)    ' 5 Second Delay
    outa[noparse][[/noparse]3..5]~                  ' Pins 3..5 Low
    waitcnt(clkfreq *3  + cnt)   ' 3 Second Delay
    outa[noparse][[/noparse]3..5]~~                 ' Pins 3..5 High
    waitcnt(clkfreq*5 + cnt)     ' 5 Second Delay

I hope that helps a bit.

Regards,

Coley
