ZBasic Forum

This is my first stab at multitasking. My task stack is 50 bytes.

Just before starting my main loop I start the task with...

The task is... Pin16 has a square wave ZC from a TW523.

No matter how long the app runs, cnt never exceeds 1, indicating the task only gets called once.

Do I need to wrap the task procedure in a Do:Loop?

Code: Select all

Sub TTLTask()

  Call WaitForInterrupt(zxPinChange, INT0)     	'pin16 = ZC
  cnt = cnt + 1
     
End Sub

The End Sub effectively ends the task. So yes you do need some kind of loop if you want the task to do more work.

Thanks - it works as expected with a loop.
