I have made a few tweaks and the code compiles ok, but when I run the simulator it stops at main:end (before the multi task threads run).
Picaxe Manual2, page 9: simtask directive
#simtask all/0/1/2/3 Programming Editor Only
The task to follow during simulation when using parallel multi-tasking M2 parts.
If no task is specified task 0 will be automatically traced.
Multiple tasks can also be traced at the same time by using ‘all’
Is main:end in the right place?
Also, I had assumed that the thread numbering needed to start with 0.
There is an implicit start0 at the start of any program, so in your case before :
let cycles = 10
You are right : the correct command to be used when multitasking is
suspend 0
, NOT END
The others tasks are infinites loops...
Also, I need the alarm code to run only once (when the fault is detected), not infinitely.
I guess I need to goto start1 to continue where the alarm was triggered?
So : replace
goto alarm
with
gosub /return
The GOTO command is always a source of problems...

Note that all tasks will start at the same time.
Actually :
- first line from start0
- first line from start1
- first line from start2
- second line from start0
- second line from start1
- second line from start2
- third line from start0
- and so on
If you want do initialze some things before starting 1 and 2
you have to suspend them at the very beginning of start0, and resume them at the end of start0.
