AVR32
« on: August 25, 2007, 02:49:04 PM »
Hi Everyone,

I got a hold of an AVR32 Eval board EVK1100 to play with (my boss is really nice!), I like some of the featurs, but I am a little confused.

Since the AVR32 can only support an AREF / AVCC 3.3VDC will this be a problem using it with the Sharp IR range finder?   If so, why/how would you do it?

Any ideas?

IIRC most Sharp IR range finders take a 5v input and output  0 - 2.5v.
So if anything a 3.3v reference will get you better resolution.

Here is a helpful article on sharp IR: http://www.acroname.com/robotics/info/articles/irlinear/irlinear.html

Hey, while on the subject, do any of these have ADCs?  I'm looking for a microcontroller running at about 200MIPS with at least 4 ADCs.

Yeah, I should have mentioned I looked though that already, but I was hoping someone my have caught something that I might have missed.  Amtel seems to also have another 32bit series running at ~200 MIPS with ADCs but WITHOUT a dsp engine.  I just can't win.  Can anyone help me win? I just wanna win once.
