46  Using Arduino / General Electronics / Re: Parts Database - PartKeepr on: February 04, 2013, 07:51:34 pm
Rather steep entry considering that you need to be very adept at running a web server to use this.  While I do run a web server, I have to wonder how many Arduino users have that luxury.

Compiling ImageMagicik into PHP is likely to be beyond most Arduino users as well. 
Creating the MySQL database will most likely stump the average Arduino user as well.

I can write a simple Excel spreadsheet to do what PartKeeper does in less time than it took to read the install docs for PartKeeper.

This seems to be more of a Rube Goldberg method of tracking parts inventory than an actually useful, easily implemented solution.
47  Using Arduino / Project Guidance / Re: Arduino Uno or Labjack U3 for new project?????? on: February 04, 2013, 07:21:01 pm
None of the FREE PC to Arduino interfaces comes close to what LJStreamUD does, and LJStreamUD is FREE with the LabJack.  As for disconnecting the Arduino, that adds another two levels of complexity as the OP will need to arrange for a way to store the data samples while disconnected from the PC, as well as providing for a power supply.  Since time, effort, and stress are major concerns according to the OP, but price is not, LabJack is hands down a simpler, less stress, less effort solution for this scenario.  Time to solution and amount of programming are absolutely less with the LabJack. 

I based my suggestion on the OP's stated project guidelines.

Considering the inclusion of LJStreamUD with the LabJack U3, that would certainly mean a quicker time-to-solution with LabJack U3 than with Arduino Uno.  LJStreamUD is an all-inclusive data acquisition software package, that will automatically create a tab-delimited ASCII file of your data. With Arduino Uno you would need to develop this data handling on your own.

As for project support, LabJack has a very active support forum at http://forums.labjack.com/index.php?showforum=16, and of course Arduino has this forum.  I guess it boils down to deciding if you want a basically plug-and-play data acquisition application, or if you prefer to write your own.

Giving us a link to the specific weatherstation that you bought would be a good start.

How much code space does a minimal useful ControlCore application use?

The ControlCore firmware takes about 48K, and a big program (100 I/O 10 control loops and misc logic...)  ~5k

Quote
Would the system be Open Source? Free to use?

ControlCore is not open source, the IDE programing environment is free, however each device will need to be licensed ( about 10$ / license ) .

Your welcome to give our IDE a spin, no hardware required, you can set the environment on simulate, and get a feel for how to program in ControlCore.

Download The basic version here

With the plethora of FREE Arduino programming alternatives, including a few graphical versions, I seriously doubt that you will get much traction with a per device licensing scheme.

Looks brilliant...

What's it like to learn from?- does it have lots of exercises, for example?

It's not really a textbook in that it has exercises at the end of each chapter.  It does have enough examples in each section to throughly test your grasp of the information however.

I think this would be a great idea.  It would be great if you supported this http://www.seeedstudio.com/depot/seeeduino-mega-p-717.html?cPath=132_133 version of the Mega 2560 since it breaks out ALL the pins on the 2560 chip.  It would just be a matter of including the extra pin mapping in your code.

I just picked up "Practical Electronics for Inventors, 3rd edition"  This is a GREAT book for learning electronics.  It has new chapters on microcontrollers, sensors, and software tools.  This is a wonderful educational text as well as a great reference to virtually every electronic component that you can ever imagine - the section on sensors even included SparkFun SKU numbers to help you quickly find the ones that you may be interested in.  The previous editions were horribly riddled with errors - the errata for the 2nd edition was over 20 pages long.    This new 3rd edition was co-authored by Simon Monk, known on here as Si.  With his help, this 3rd edition has pretty much eliminated the entire errata.  Simon Monk has written several Arduino books, and he is active on this forum.  I recommend that anyone looking for a great electronics text take a look at this book.

The TEA5767 uses an i2c interface - very easily accomplished with an Arduino

Take a look at these:

Try looking at more than just the graph.  Bascom AVR is popular in places like Iran - which has a search volume index of 100 for Bascom AVR and 0 for Arduino IDE, and BASCOM AVR has a  search volume index of 1 in the US. Whereas Arduino IDE has a search volume index of 60 in the United States and 0 in Iran.

I would say that the Google Trends would indicate that Bascom AVR is the clear winner over Arduino IDE if your goal is to be with the "cool kids" in Iran.

More to the point, comparing a FREE IDE with a COMMERCIAL IDE is pure folly.

Let's compare the two in some real world applications that Arduino is being used in today.  Let's see your Bascom AVR code to control a UAV.   Let's see your Bascom AVR code to control all the timers and relays for a hydroponic system or a salt water aquarium.  Let's see your Bascom AVR code to control a 8*8*8 LED cube.

I'll be waiting for ANYONE to show me that Bascom AVR can do that in less space.

1) Arduino IDE and Arduino Uno (or other boards) are good for beginners because you can quickly get familiar with AVR chips, you can blink your first LED in 30-60 minutes from the moment when you get the Arduino Uno board. Apart from that, there is no other serious advantage.

So, are you saying that Arduino Uno and Arduino IDE are only good for blinking LED's?

2) Arduino IDE is quite inflexible. It is designed to work well with the Arduino boards it has in its list. If you want to use Arduino IDE for stand alone AVRs you run quickly into huge complications and the entire programming process starts to look more like hacking than serious work.

Arduino IDE was DESIGNED for Arduino boards.  If you want to work with something else, get a development environment designed for that product.  It is, however, rather trivial to use the Arduino IDE along with an external programmer to program standalone AVR chips.

3) Another problem with Arduino IDE is that it does not have a debugger, it does not have a simulator. You can not run your programs step by step to find errors.

Again, the Arduino IDE was never intended to provide debugging or simulation capabilities, so to claim that the lack of them is a problem with the Arduino IDE is disingenuous.

4) The hex file size generated by Arduino IDE is also a problem. A source code that just blink a LED, once compiled, generates a hex file greater than 1 Kbyte. Same code in Bascom is below 250 bytes and in IAR below 100 bytes.

Virtually ANY development environment can give better compiled size if you are willing to PAY for such optimization.  Arduino IDE is FREE, so once again complaining that it is not the most optimized compiler is disingenuous.

I have purchased several of the same RGB LED's that you linked to.  I purchase them from ebay for 1/10 of the price listed on that site.

Yea, but so many of us 'experts' like to snow the newcomers (and impress our peers) to make any subject or question from a beginner to be as confusing and irrelevant as possible. It's what we do as a hobby and our hobbies make us happier in life.  smiley-grin

Well, I guess you could include average junction temperature, operating environment (To include season, prevailing winds, climatic variances, global warming coefficient, and magnetic correction), as well as the heat generated by the proximity of the end user.  If the project is in dairy country, may need to add a correction factor to the global warming coefficient as well.

 So bottom line simple low power leds do need series current limiting resistors to protect the led and the output pin, but anything from 200 to 1K ohms will do the job safely and effectively.

That sounds like the best "keep it simple" advice that I have ever heard in regards to LED's
