1  Development / Suggestions for the Arduino Project / Re: Regression between uno and uno R2 VALIDATED. HARDWARE PROBLEM CONFIRMED on: November 11, 2011, 07:54:24 am
One simple solution to this issue for all Arduinos out in the field is a simple 2 pin jumper with a 5V6 Zener diode fitted (BZX55B5V6-TR ~ 3 cents), along with clear polarity markings for fitting across pins 5 & 6 of the ISP header. Such a solution could be posted 1st class folded in thin cardboard inside a standard envelope for next to nothing for those who want it. Of course it would need to be tested, I don't have such a zener diode handy.

In terms of implementation one would need to mount the zener on the side of the open jumper because:
1) It needs to be low profile (not interfere with shields etc..)
2) It then acts as a physical polariser, the zener physically prevents it being fitted around the incorrect way as it hits pins 3 and 4.

Hi I changed the DuinOS.h file section '/* Scheduler include files. */'

from
#include "DuinOS\FreeRTOS.h"
#include "DuinOS\task.h"

to
#include "DuinOS/FreeRTOS.h"
#include "DuinOS/task.h"

To make it work on Mac OSX

Then it compiled and uploaded, now playing with it thanks Julian

Very Cool that you used FreeRTOS been meaning to play with it for some time, this is a perfect excuse..
