I do worry a little about the so called arduino "form factor compatablity" with the 32 bit boards. As any 32 bit board is bound to be a 3.3vdc board and most arduino boards and existing shields are 5vdc is there room for electrical damage here?

PIC32 apparently has 5V-tolerant/compatible IO, except for the analog pins, which have added protection.

Just which shields ARE compatible with a 3.3V cpu, anyway, and how do you tell them to be so (rather than carefully level-converting the digital pins back up to 5V, for example.)  I suppose it would be easy if you just put 3.3V on the "5V" power pin and let things run, but pic32 (for example) carefully puts a real 5V there (which is one of the compatibility issues I was referring to.)

I see Mircochip has come out with the chipKIT32....its compatiable with arduino shields and has more I/O pins then the ONO,,,should I be worried that this could be the end of the Arduino???????


There is a lot more to the Arduino then just the hardware. I'm certainly not concerned, are you?

Indeed, Arduino can be in trouble if:

  • - there are supply problems and prices are increasing (or prices can't be lowered); - prices are already high

  • - all the projects which made Arduino famous will be fully adapted (or their authors will migrate) to Chipkit and other compatible boards - is happening already



Frustrations in making transition (software and hardware problems) to Arduino clones can strengthen the Arduino position. But, something must be done for sure. You can't just sit on your leader chair without progress. Still, 5Vcc is a barrier to many hobbyists and Chipkit example in adapting a 3.3V chip to be a 5V board is to be followed.

Also, "the model" Microchip is making in quietly supporting  the Chipkit boards with specialized engineers is definitely to be followed. I hope Atmel is reading (or someone pointing them to) this.

These two statements are utter rubbish and show you don't know what you are talking about.

1. I'm relating to realities in my zone (is all what it matters).
2. For RepRap is there a project started for Chipkit boards. And expect more where speed is needed.

My post suggest progress to Arduino platforms (and that you can't ignore "the signs"). Google chose Arduino platform for their ADK assuring Arduino existance for a long time from now on but also here are more powerful (and cheaper?) platforms for that.

But I'm sure Arduino developers will take into account all of these.
