if i can get them for a $1 then heh i would buy a bunch and not worry about it being a overkill. A overkill is bad when it cost more. Why pay for more when you can do it for less lol but if you get more for less then its different lol
seems like a good IC to use alot... of course ill start with a dev board tho. But when i do need to create something im sure that will fit in the requirements... if not there are a ton more and all are about same price as PIC.
I know there isnt alot of support for ARM7 like PIC here but im sure ill learn alot and help alot.
They aren't "nextgen" per se. They are more like the ARM series but designed from scratch to be a microcontroller rather than a microprocessor. The M3 is the equivelant of the ARM7, and so on and so forth. I'm planning to use the M3 for the next thing I build because of the packaging and the programmer and IDE can be had for a fair price.
Jason: there's where I am not fully comprehending this whole jtag thing.
it seems to me that some arm chips (lpc for example) have internal bootloader that once up on reset can receive data on its own. so why do we need such an expensive device?
also, some of the schematics I have seen about jtag seems to suggest that it is taking signals from a db25 connector (rst, tms, tdi, tdo and tck), buffer them through a dual 232 chip and then dump them onto the same pins on the chip, with the rst signal reversed. that doesn't seem to be too difficult to wire up by oneself; and why do they need that buffering (for speed?)? so it seems to me the simplest thing would be to wire everything straight and then invert the rst signal (with a transistor). or if you are really cheap, program a dip8 pic to buffer it.
then there seems to be some compatibility issues as to certain cables are compatible with certain chips but not others so I am not sure where to begin.
