Du weißt schon, daß das ein Wiederspruch ist. Eine FAT ( File Allocation Table) braucht man um zu weissen wo, in welc...

Re: Writing a library? (Beginner)

I did a countdown timer using 7 segment LEDs. You may get some ideas on structure and functions by looking at that code. You can find it at with my code at the web site linked from my signature below.

My problem right now is that code is not working above.
My problem is that you have not described what the code is doing, or what you expect it to do, or how those two are different.

Portante a 36kHz

Salve!
Dovrei creare un'onda quadra a 36kHz e allo stesso tempo verificare la presenza di un segnale digitale su un pin (il classico led emettitore con ricevitore TSOP)

E' possibile rilevare la presenza mentre il segnale portante è in LOW? ce la fa ar...

Re: Eternet Shield + Mega 1280 Problem !!!

You do not need that wiring hack. That would only apply to ethernet shields without the ICSP connector socket. That is the connection for the SPI data lines. Your original problem was probably code related.

Re: PT100 sensor - help a beginner?

Posted: 01 Apr 2013 02:10 AM PDT

OK, if you can't find any thermistors good for +125 on eBay, they probably don't exist, and you are right to use the PT100 - again. Hopefully it didn't cost more than about $5 anyway. I really can't comment on their use without amplification. I needed ...

No sorry, I have no datasheet because they are bits from different places.

Some are from my toner printer chip I want to rewrite, and some other from old TV's to try and test.

I'll have a look at the link but I'm very bad in programming and understandi...

Danke für die Antworten.
Gibte es den einen Port, den ich einfach mit dem Arduino verbinden kann ohne einen IC zu benutzen, da ich keine weiteren teile kaufen möchte.

Re: ATMEGA 1284 boot loader

Posted: 01 Apr 2013 01:54 AM PDT

The 1284p (328p) works fine @16MHz and 3V3. Set full swing oscillator to be safe..
Atmel guarantees the parameters in -40..+85 degC region, therefore the official MHz rating for 3V3 is lower..

A Favorite Hack for April Fool’s Day

Of all the MIT campus pranks, one of the lesser known but classiest was when this upside down living room arrangement appeared on the underside of the MIT Media Lab Arch in April 2010, complete with a billiards table, office style plant, leather armchairs, and most importantly, a plan of the hack.  Maybe next year someone can invent an anti-gravity device so sleep-deprived students can take a nap up there.

So this is not the best place to gain information on c++ programming from more experienced c++ programmers such as yourself?
