1  Community / Bar Sport / Re: Will the Due be a dud? on: December 31, 2011, 05:19:36 pm
I think the Arduino Due is more of a psychological blow to competitors than anything.

Until a few years ago, the Arduino platform had always had the performance advantage. And now, having a Due (which could mean "Version 2" in Italian) that leap frogs the competition (2-3 x the performance of the DSPic stuff!!!), it silences those people who have criticized the Arduino platform for being lackluster and underwhelming.

You should read the anti-Arduino posts that are spreading across the web, like the ones posted at the end of this article:

Like Leon Heller on Avr Freaks, I think the irrational feedback found on those sites is competitor propaganda that's making a serious effort at changing hearts and minds...IMHO

Yes, the performance of the Due is not needed since the Mega can address many of the applications that the Due will handle. However, having the Due with a powerful core will entice power users from defecting to competitor platforms, which is good business for Arduino, since user support from this experienced base has always also been an inherent advantage of the Arduino platform.

I must admit, I'm not much of an Arduino user, but I do occasionally wonder in these forums for insight. And although I sometimes get shocked and awed with the Arduino noobs and their fascination with the LED projects, at least it shows me that they're actually using the platform. Go to the Arduino competitor forums, and there just isn't that much going on.

I'm trying to understand more about FFT in general. Do you guys recommend any material to help us better grasp what it does?

Hi Terry,

Here's some Fets that are logic level compatible which I didn't include in my list:

I'm not sure about your rationale behind this...
When starting a project, most newbies usually obtain the parts listed on that particular project instead of using what they have on hand. Getting the project up and running is usually more difficult when using non project-specific parts. Just MHO.

Good luck

Here's a short list of my IC's:

I have a bad habit of ordering complete component lists for projects I never even get to start. Over the years, I've horded hundreds of IC's. I recently began to compile a list, which you see on the link. It's a small fraction of the countless unopened bags I have in my room.

Favorite IC: I have to say, the more useful chips are the ones most people take for granted. Yes voltage regulators are quiet useful, but if it were not for those MAX232 chips, I dare say, the early days of our processors would have been very difficult. To this day, they're quiet a requirement on many of our projects.

I'm interested in doing something similar, can any one tell me which transistor the OP is using to amplify the 20mA to 240mA with the PWM signal...

Is the diagram correct, on the first page, I really don't want to blow anything up.

Thank you for your quick reply John.

Do you know of a project that has already accomplished this feat? I don't want to reinvent the wheel for something that I'm sure has been done before.

These parallel eeproms are old technology

I'm so sorry to post about something obvious.

However, after doing several searches, including reading several posts about interfacing with eproms, I have yet to find a solution.

I'm currently trying to read/write to a AT28C256 eeprom and have not found much documentation. I seem to find many posts about Ic2 eeproms and SPI eeproms, but not parallel eeproms.

Can any one steer me to the right direction.

Thank you so much

Thank you so much for this contribution!

Have you taken a look at Ti's ADS1211.
It's a pin for pin drop-in replacement of the ADS1213 with notable improvements:

*24bit ADC

I would think your library should also work with this other part with minimal modifications!
