Aha, the PIC chip! Cool. Yeah, that's a very well established platform. I have heard good things about them, but have only done stuff with AVR/Atmel, because it's cheaper.
The normal approach with this sort of thing is to write the drivers in a chip specific format, which then run on the microcontroller (PIC, AVR, ARM, etc.) which means an additional layer of complexity. This is good for autonomous stuff, but if you're going to have a computer connected all the time it's an extra layer of complexity. So yes, I have actually taken the microcontroller out of the arduino board, and am just using it to relay raw serial data from flash. So all the stuff flash is sending is just hex codes, pretty low level to deal with in flash, but quite easy to write drivers for using OO code. Arduino and PIC native code isn't really OO (arduino is basically C, AFAIK), so I think it's probably easier to write drivers in Flash, if you don't need super fast speeds. Also, the same flash code can be used on mac, windows, etc - although this would be true if you used a microcontroller as well. Mostly, I do these things not because they're useful, but because I can :) cheers, Alias 2008/5/6 <[EMAIL PROTECTED]>: > I like microchip because of it's low level possibilities, but they are very > user friendly as well (it helps to buy a hardware debugger though).
