In one project I use Picaxe 20M2 and a program on Logicator. A sub routine under title"start1" makes an led blink when a " compare" command is satisfied. From time to time the subroutine is not executed although the condition calls for it. Then it never work again until I do a hard reset, that is turn off the power supply. Is there some particular precautions to observe in drawing the main (start) part of the flowsheet to avoid the lock up of a sub routine?
Sub routine not performing
- Thread starter Gapak
- Start date
Finally, here is my flowsheet.
The project is the control of a small waterfall.
Pressing a push button initiate the"NORMAL" procedure: pump runs for 10 minutes unless you press the button again before that time.
Otherwise an other procedure called "CYCLE" runs the pump 5 minutes, stops for 30 minutes then repeats. This automatic cycle can be interrupted by pressing the button; this will reinstate the"NORMAL" procedure or shut down the pump.
A level control makes an led blink ( the Start1 sub routine in question) if the water level is too low. It will also switch off the automatic cycle.
Thanks for trying to find why from time to time the sub routine is not working: no blinking when water level is low. I have checked the voltage on the input port and found it correct.

"Start1" is an independent task which toggles output B.5 when pin C.2 input is low. The only reason it would not be running would seem to be when C.2 input is not low.
There is nothing I could see in the program which would cause incorrect behaviour of "Start1".
What form does this level control take and what voltage are you reading on input C.2 ? I am wondering if it is an issue of reading an analogue signal using a digital input ?
