I have a project using a mini for which I have had some issues. I have tracked the issue down to pin 13, and would assume that the inline 1k resistor is to blame.
My query is as follows:
can I simply remove the resistor and bridge the pads? would this then make pin 13 act EXACTLY the same as other I/O pins? is there any code in the Arduino bootloader which makes pin 13 act in any different way than the other I/O pins?
Thanks for the help. Before it is suggested, I can't relocate away from pin 13 as my PCBs are already manufactured and all I/O pins are used. I realise that the boot sequence has pin 13 raised high three times on start, but this should not effect me.
