Well, unfortunately I'm in the market again. My company looks like it's not going to quite make it through the re-de-pression or whatever we're calling this. I'd prefer something in the Dayton OH area, but anything's negotiable. Resume and refs on request. I'd appreciate any lead

I think a lot of us here had other microcontroller experience when we started with AVR's. I started out many years ago with the Z80, then the 8051, 8085, 6800, then PIC's and finally AVR's. Almost entirely in assembly language and I actually built the circuits that the microcontr

Why only one month? What is it specifically that you want to do with an AVR? There are lots of application notes at the Atmel website and at AVRFreaks. If you have some specific thing in mind that you need to learn, you might get more answers. Zack On Tue, Aug 18, 2009 at 4:14 PM

OK. This has onboard handling of the air interface which does away with any additional coding at your end other than some form of CRC etc. A quick look at the datasheet says that it can be setup for 4800, 8, ODD, 1 which would match your medical data output so I can't see any rea

Basically, the only reason to use a PIC is because "we've always done it that way". I've heard that the PIC was actually designed by another company in the late '70s; they thought it was dead; sold it to Microchip who launched a marketing blitz for it. Back when our only other op
