Alternating loop

Archiver

Hi all!

I have a need to make my stamp program alternate between two
different sets of code every pass through the program.

I am running two sonar modules and I think they are setting each
other off because they are pinging one right after the other. If I
could make the program alternate it would ping one then the next time
through the program it would ping the other.

TIA

Doug,


You can do that with a State Machine. i.e.,

laststate var bit
laststate=0

Main:
if laststate =1 then Check_sonar2

Check_sonar1:
"get data from Sonar1"
Laststate=1
goto main

Check_sonar2:
"get data from sonar2"
laststate=0
goto main

I'm sure there is a more elegant solution but this might work.

So you want to fire one module during one pass through the loop, then the
other on the next pass? Just use a bit variable -- when it is true, fire one
module, false, fire the other. Just toggle the value each pass.
