I have an Arduino Due and I have an application that uses FT-CAN (11898-3, Low speed Can). Does anyone know if the Can controller built in the DUE micro will control FT-CAN Transceivers TJA1054t or TJA1055.
I thought I heard that the CAN is not hooked up on the Due but I might confused.
Either way the best answer is to recommend the Arduino.cc forum which would give you an answer very quickly. http://www.arduino.cc/forum

I am asking this well ahead of applying it to get myself a chance to study content of answers.
Basically the question is if there is Arduino compatible chip (I am not interested in boards) which does not need external crystal to keep it in close enough sync to run serial (232) communication. To mine knowledge the atmegas builtin crystals are not very well calibrated. The speed of communication does not need to be high in fact I see no problem for less then 0.3kb per second.
I know its off topic, but best I have found was RTL8710 Roughly the the atmegas price, enough i/a with extra wifi as bonus. In case somebody is looking for answer
In a project, we need to drive a linear motor module (some high tech fancy industry thing) with something as simple as an Arduino. Basically we need to get the speed of the Motor and send its new commands back. In between I'll implement a controller and logic.
To be honest, I only got a rough idea, how industry (ethernet or other) standard/interfaces work, and I got absolutely no idea, if it is even possible to interface such a fancy thing with an Arduino.
I've got the options for the following things:
Sercos III, Profinet IO, EtherNet/IP, EtherCat
possibly also: CANopen, Profibus
Are there any libraries/known projects in this direction? Or is it strictly impossible? I found 2 projects about profibus, but they didn't really seem to be reproducable in the near feature, without significant efforts.
Thanks for any hints, advices etc.!
Very interessting discussion about CAN on Arduino DUE: http://forum.arduino.cc/index.php?topic=131096.0 Same should work for the DigiX as it is 100% pin- and code compatible (and still available ;-) )
As a hardware illiterate software guy trying to do a hardware prototype, will appreciate an answer to this.
One of the hardware components that I need to integrate supports only lpc interface. Is there a way to have it work with arduino? Does the question even make sense? What are my options with this?
I tried doing a bit of research on this, but simply didn't understand anything, nor was there any direct reference to anything that makes this possible.
I guess you're talking about Intel's Low Pin Count protocol.
And I guess, you're trying to make a BIOS flasher, aren't you? ;-)
Is there a way to have it work with arduino?
yes
Does the question even make sense?
of course
What are my options with this?
Have a look at that article and this thread… It shows and gets into some details in how to implement it.
As you say you're a software guy, just consider that you're trying to implement some kind of network procotol stack, starting from the basic building blocks. You need to take care of sending the bits over the pins, take care of the timings, output the start/end stop flags if there are… And then implement a buffer on top of that to parse a byte, and then bytes, etc…
All you need to do that is to follow the sepecification, and plug a few pins on the Arduino.
Well, your question should be closed for lack of research effort, but hence you say you tried but are still lost, I hope my insights will help you come back and ask a real on-topic question with something you actually tried.

for an art-project I want to control an array of say 60 to 600 lightbulbs. Each lightbulb should have his own radio-remote. So one remote should switches only one bulb on and off.
I want to do this with an arduino Uno. Do you think this is possible? Is there a better choice?
The remotes I thought of using have 8bit encoding.
As I`m only in possession of dangerous half-knowledge, I thought I ask you guys first.
thanks in advance
Without more details it is hard to say. I think it would be more appropriate to use only one remote and 600 receivers though. If you have only 8 bit encoding you will be limited to 256 receivers unless you introduce an additional code on top of the existing protocoll.
However you would have to keep in mind that the Arduino has only very limited RAM. So the tight RAM constraints could be another issue.
But unless you provide more details (what are you aiming at, which remotes, how fast do you want to switch the bulbs) it is impossible to provide a better answer.
I've ripped open an old Pentium desktop. The main board is a Zida 5svx. I got to know from the manual (which i downloaded from the internet) the location of the ROM chip on the board, and took it out. It was mentioned in the manual that the chip was a Flash EEPROM.
Now, what I am interested in is this: Is there a way to erase the ROM and flash it with, say a C program to blink an LED (i know this might put you into a fit of laughter, but read on all the same), or control a motor?
I also want to know if I can construct a mega-sized micro-controller with the left-over Pentium, some MBs of RAM, and this ROM.
Any suggestions?
P.S: I know that such a uC will require appropriate power supply setup and things.
The key is in getting and deeply studying the manufacturer's datasheets for each device you remove and wish to reuse. I am supposing that since you asked the question that you did that you are not a professional electrical engineer - that's OK, but you will need to do hours, days, or weeks of study to truly understand the datasheets well enough to successfully reuse your motherboard chips because they are written for professional engineers with years of experience, and unfortunately they were not written to be understood by hobbyists. If you can succeed in acquiring and thoroughly understanding all of the datasheets (and the related user's guides as well for the more complex chips) then you have made it to the point where you might be able to start a custom design based on your recovered parts, on paper at least. In order to test your design and insure that each part of it is working will require at least an oscilloscope and volt meter - and the knowledge of how to use them. An understanding of basic electronics is essential, you will not succeed without it. Very good soldering/rework/assembly skills will be required as well if you hope to have your design truly work - you can do everything else right and it can still fail if your skills in this area are lacking. There is simply not enough time for me to advise you on everything you will need to know - but if you are motivated, dedicated, and you don't give up when setbacks and roadblocks occur (and trust me, they occur all too frequently for even the best engineers and best designs) - meaning that you are not easily frustrated when things don't work - then you have a chance at success. I wish you all the best, and try to have fun while doing it (important in case fun is all you ever get out of your project). :)
