I know how to program (Computer Scientist), very well. It's what I do for a living. Well then you would know the supreme advantage of the HUGE library of software thats for the Arduino. Its like linux, its sometimes more time consuming to eval all the different libs... The shields and arduino UNO a...

Do you have the ft232 driver installed (i should add for the chip id you have installed onto your pcb)?
Is you r ft232 chip operating correctly?
Do you have a known ft232 usb->uart dongle that you could wire up to the uart using flywires?

Why do you say that? How long would it take you to design/build/have manufactured the same thing? If time is an issue, you can get that $80 board in your hands the next day! Thanks, I got some of the on-sale versions. 80 bucks is otherwise RIDICULOUSLY overpriced for their newer models. yes $80 is ...

NXP probably has largest market share, or maybe ST. the STM32F4DISCOVERY is really sophisticated... and daunting. I have one. Without so many ADCs, the graduate from 8 bitters can go to the mbed.org things. Lots of collaboration/contributed code. Novel on-line compiler and downloader. I agree. I st...

Yes, one of the many C compilers. This is a big negative to me(as a hobbyist) about PICs, no good free tools. Arduino has great free tools, and as a result has a HUGE library of code to build on. Even STM has a free gnu C compiler and tools. That said, I have used CCS Pic C compiler. I liked it, but...

Re: Arduino Pro Mini - suitable as a first board?

Another sublety,
the teensy uses a custom library. So code you write using teensy lib is not portable to another arduino based chip.

I'd recommend a ModernDevice.com RBBB + usb adapter.

Re: MicroSD Shield (DEV-09802)

link would be convenient.

Most like its being used as a voltage convertor(5v-3.3v) for the data lines.

When I add sd cards to 5v mcus I use a plain hex convertor as a level shifter, bridging 5v mcu to the 3.3 sd standard.
Its 1000x more reliable than the voltage dividers you see on the net.

realterm, teraterm - free serial consoles. If you want something that simplifies things by using buttons and textboxes you will have to write your own. Then things like ease of development, portability and deployment come into play. Tcl/tk has super easy serial support, runs on darn near anything pr...

Try using a flux pen to flux the joint. You are using electronic solder right? It should be fine wire type (not 1/8" diameter pipe solder) 1-2 seconds MAX to heat and solder a joint. 25w is a bit small, I use a 70w (analog from SFE)and its definitely fine. One thing, is each tip is different, and mo...

You still need a different license for each machine. You can't run it on an unlicensed PC. Hi, The Rowley License page indicates that the the Pro license is per developer and they give a specific example of one developer using multiple machines. (do they use a dongle? passphrasekey?)

Search for yagarto or winarm, or eclipse + arm ( or eclipse codesourcery) for free GCC and Eclipse. Your board supposedly came with a sw loader. 'Free' is the most time intensive way to go, as you have to work out tons of options. This is the route I have gone as I am a poor sw developer who simply ...

Actually, the fix for most libraries is pretty simple - just as dksmall said. One line and all is well. The libraries are easy to find and edit even if the error message is obscure. However, anything using the wire library needs a number of edits. they, too, are fairly simple but more extensive (th...

Use Arduino 0.23. The errors you see are from changes made to Arduino 1.0. Look at the change notes, and google your error code and you will see. Most folks libraries are not being updated. Theres no set 'standard' for the fixes yet (everything that uses Wire.h has to be changed, and thats a ton of ...
