I've noticed an issue when autoreset occurs where the pins 'pulse' which is causing me some problems. Note, when I start the arduino normally, this 'pulsing' doesn't seem to occur, but only when I connect a USB cable, click on the 'Tools' menu or when I close the 'Serial Monitor' in the IDE.
Is there a way to not have the pins pulse?
(This is in follow up to the thread: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1295273279/3#3
The problem is that I'm using ArduinoAndy's PLC watchdog as a safety circuit. (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1267907942/0
). However, when this 'autoreset' problem occurs, the pins pulse, causing my watchdog to be enabled...which in my case would try and turn on various LPG burners and fans and water pumps. Obviously this is not ideal.
So, to the question: Is there a way to NOT have this 'pulse' occur during auto-reset.
The problem doesn't occur if I manually reset.
The problem doesn't occur during normal power up.
The problem only seems to occur during this 'auto reset'.
Obviously going through and disabling auto reset _could_ be construed as a solution, but I'm a little worried that there's something more sinister going on here...
I have tried this on 2 Dieceimila's and both operate exactly the same.
Any help appreciated...
