I'd like to suggest that this is actually a rather serious bug. I'm using the hardware watchdog system suggested by ArduinoAndy (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1267907942/0
) and whenever I go near the tools menu, OR close the 'Serial Monitor' it causes this reset, which causes pins to pulse...
(It drove me nuts, trying to debug what was going on!!!)
Considering that I'd like to use the arduino as a safety system for an LPG burner, this 'helpful' auto scanning thing has wildly inappropriate consequences! Of course, in the field, I'll have a switch on the PLC to physically isolate the pins from the arduino, but this seems a bit overkill, especially for what appears to be software fault (in the bootloader?).
I suppose a better question is: Is there a way to NOT have the output pins 'dance'....ever? Why does any pin ever pulse? Obviously pins 0 and 1 are used to program via usb, but everything else should remain inert.
PS: I'm using a diecimilaeried
, do you have a link describing what you've done (especially your hacked rxtxlib) to work around this issue?...Thanks.
