I'm quite new to micro controllers so this may be a stupid question but I just don't understand the pricing strategy around these products.
I have started out (and continuing ) my first project using the arduino. Outstanding starting point with easy on-ramp experience.
I found the atmega a bit cramped for space and timers, so I thought I would give the atmega2560 a try. Nice improvement, but when I looked at prices on mouser and digikey I have a hard time understanding the price differential. It would be easy to understand if they were the only solution, but the xmega seems far more capable and a lesser price, and many ARM chips are substantially cheaper with more capabilities and faster and with the same claims of lowest power.
I thought I would try the xmega ATxmega256A3U, but that would require me to use some other development environment. I've tried in vain to understand the avr studio 6.0, this seems like some monster with poor documentation, and very bad performance. (BTW "“ this product is in desperate need of a splash screen that comes up when starting to let the user know it is starting"“ not 5 minutes after - this would prevent starting multiple session. I'm not complaining "“ if I had paid $$$ for it I would complain)
Back to the point "“ is the atmega2560 more advanced? Or is no longer in production and the price is for a scarce supply? If I were to build a product based on this chip, would I find it at the end of life before I start?
