Develope a AFR-meter

If they are using an AVR then how is it a step backwards to use another AVR? You've got me stumped on that one - your statement doesn't make any sense.

They are using the Atmega168 for the newest DIY version of their wideband product. This is the exact same microcontroller found on the latest arduino. Does that necessarily mean they used the arduino environment or platform to develop with - no. But I'm willing to bet they used gcc and some form of IDE (which is what the arduino environment is really). I actually can't see in any way how it would be a step backward for ANYONE to use an existing, well supported and open environment for development, especially if that environment supports the microcontroller you are going to/already are using.

TE came out with their first widebands before AVR GCC was perfected. My guess is that their first widebands were either done in assembly or a non AVR GCC compiler, probably IAR C as it is generally believed to be the best C compiler for AVR.

Their latest products may very well use AVR GCC. If you use Arduino then you are certainly using AVR GCC, if you are using AVR GCC does not mean you are using Arduino.

I am not saying Arduino is bad, but if you already know ASM and C why would you want to use Arduino and add an extra layer of stuff?

Because it comes with a large code base - so you don't HAVE to write everything yourself. You don't have to use the IDE either if you don't want, you can always just take their code and compile it directly. The arduino community is large and well supported - so there is help if you need it at some point.

There's also a big code base of AVR C and asm code around, there's no valid reason to ever use Failduino.
