pretty cool little processor...

i thought that there was another chip out there that did all of that
already...hmm.. i can't remember which one it was....

now that's a good deal.

i do.  i'm new to this diy dfi thing, so what do you recomemd to look for in
microcontrollers when building your own dfi.  i've used motorola's 68hc11's (i
don't think that they could hack it..) and some strong arm stuff to build
dataloggers and other non-car related devices.  is there an advantage to using
PIC?

i figured a microcontroller that had lots of I/0 lines @ 10 to 15bits of
resolution, decent processor speed,  lots of RAM and EEPROM, and uart.  what
else?

thanks
