Ciao,
a quanto pare è stato risolto il bug nel boot-loader che impediva l'uso del watchdog.
Servono però dei test per fare in modo tale che la modifica sia accettata e resa disponibili d'ora in avanti nell'IDE.

ahh ok..
Ho una stazione saldante e con saldatore a punte fine e anche lo stilo ad aria calda..
Poi per la tecnica... vedremo  smiley-wink  smiley-grin

per attrezzato intendo:
ottima techica di saldatura e buon saldatore con punta fine
oppure
stilo ad aria calda
o forno da ferlow ecc..
insomma volevo dire che il package dell'integrato è solo smd.

Without knowing what you exactly looking for, but have an idea (individual PoE) I would NOT do it in the way you asked.

IF you consider some sort of PoE for devices that are kind of "energy hungry", your first thought in principle is right: the higher ...

Look at the for loop that turns the LEDs off

Do you want it counting down from 6 or 5  - array elements are numbered from 0 upward...

Quindi ogni pin di interrupt è utile alla causa, indipendentemente dalla modalità di sleep,anche per quella a maggior risparmio  SLEEP_MODE_PWR_DOWN, giusto?

Re: PWM-Signal

Posted: 05 Feb 2013 12:06 AM PST

Drei Anmerkungen:

1.)  Dein M150 verlangt, wenn ich das Datenblatt richtig verstehe, eine PWM am Eingang.
Wenn du an den Arduino-Ausgang einen Tiefpass anschliesst, dann hast du keine PWM mehr.

2.) Zweitens: Integrieren / Mittelwerbildung.
PWM bedeutet...

Re: Wire issue with ADXL345

Posted: 05 Feb 2013 12:04 AM PST

That's right.

ADXL's INT1 pin is connected to digital pin of the Arduino board, so I can use an internal interrupt and wake up the MCU when a tap occurs.

I wrote down that interruptions occurs when MCU is awake, and when WDT finishes each cycle, but wh...
