[Diy_efi] Freescale ARM7 devices

[Brian Clough]

Greetings:

Has anyone ever looked at the Freescale MAC7100 series of ARM7 based 
microcontrollers, as the basis of a homebrew EEC?

The "Modular I/O" subsystem on these devices seems tailor made for EFI 
and Electronic Ignition applications.  Each MAC7100 device has 16 of 
these channels, enough for 8 injectors, 4 coils, and 4 other 
peripherals, such as idle air valves, etc.

I think a 32-bit microcontroller, like the ARM would make a superior EEC 
controller.  It could even run an on-board web based setup utility, 
eliminating the need for PC setup programs.

I'm a software guy, and I have a great deal of ARM programming 
experience.  I've read several online tutorials, on the software 
requirements for EFI control.

I just want to pick the brain of someone with more hardware expertise. 
I'd like to see what might be involved in such a project.
