I Actually have 2 projects in mind... A small one and a rather large one
My first project is a small controller mod to add some buttons on the bottom of my controller to have the default controls more accessable. My 2nd project is an ECU (Engine control circuit). I do know the 2nd project is a bit bigger (like huge) project but im not sure where to start... I was going to go with arduino or similar (Netduino, Maple leaf, etc) and have like a shield for them to do it, but I thought why not do it from scratch.
So here is my problems
Project 1:
- Low power (dosent need to be fast)
- 16+ IO ports
- 2 Interrupts
- Vin between 1v8 (or less) to 5v or more (I could regulate it)
Project 2:
- Pretty Strong Microcontroller
- Needs to be rather quick (30Mhz + would be nice)
- 35+ IO
- 2+ Interrupts
With project 2 (the ECU) I also need to pulse some inductive loads rather quickly (A few milliseconds each) for the injectors and I need to read the Tacho pulse (which is from an inductive load)....
I dont need any fancy comunications like CAN or anything, but reading an SD card containg settings would be nice, or maybe an EEPROM or something i dont know...
Yes I do know its a big project but I'm sick of making my arduino blink a led and I dont know what else to do with it
Some PCB design help would be nice as well (like trace width and length). Even if you cant help, just point me in the direction of somewhere I can read or use to do this project 
I will link you to my forum thread at Jaguar Forums so you can get an Idea of what I want to do with the ECU http://www.jaguarforums.com/forum/jaguar-engines-47/custom-jaguar-l-jetronic-5cu-ecu-70295/
Thank you for listening to my inquires
