The hardware documentation on the PIC32 runs to 1200 pages.
If you have ever tried to use that to do something useful it
becomes near impossible.
It is not like a big book where you have random access to any one page.
You have to tell the PDF reader what page you want to look at.
At the bare minimum you need a separate index PDF.
Attached.
I found this free PDF editor that can extract a range of pages.
This way I can break it down into workable chapters. Each chapter is
book length in the case of the PIC32. Most of the other free PDF
editors I looked at are junk.
The editor is called PDF24 and published by www.pdf24.org
I highly recommend it.
BTW there is a real time clock calendar in the PIC32 for free that would
make a great wrist watch with 312K of storage. Built into the PIC32 is
also a built in USB port. How about having your Android cell
phone talk to your watch :) The application of this boggles the mind.
How about a hi rez camera in your watch for taking pictures discreetly.

Actually someone beat you to it. Someone sold over US$10m worth of
Bluetooth watches with an e-ink display at about $110 each. It was
done just a few months ago at kickstarter.com
http://www.kickstarter.com/projects/597507018/pebble-e-paper-watch-for-iphone-and-android?ref=most-funded
while looking for the link. I also notice this tiny USB board. Have 6
I/O pins, may be good for 1/2 a rotor?

I've got to have one :)
Damn I used to be twenty years ahead of my time. The rest of the world is catching up.
That video gave me an idea for raising money for the rotary turbo compound.
I'd go with the Tiny in a heart beat if it had a BASIC.
Here is another one called a Teensy.

Paul,
I think you can put Basic in the Tiny. It is an 8 bit AVR so Bascom
will support it. I think it has support for interrupt build in as
well.

My thinking has evolved since I wrote that. It takes a huge investment in psychic
energy to adopt a processor. Once we get a simple EFI written in BASIC to work we
will want to add features. That takes power. You might as well start out with the
most powerful processor $10 can buy.
Megasquirt made that mistake. They should have started with a 32 bit 68000 instead of
a 8 bit 6800 processor. They wound up with a monster kludge. Plug in board on plug in
board.
I am liking the ARM more and more. Billions have been sold.
"By January 2008, over 10 billion ARM cores had been built, and in 2008 iSuppli
predicted that by 2011, 5 billion ARM cores will be shipping per year. As of January
2011, ARM stated that over 15 billion ARM processors have shipped."
"The ARM architectures used in smartphones, personal digital assistants and other
mobile devices range from ARMv5, in obsolete/low-end devices, to the ARM M-series, in
current high-end devices. ARMv6 processors represented a step up in performance from
standard ARMv5 cores, and are used in some cases, but Cortex processors (ARMv7) now
provide faster and more power-efficient options than all those prior generations.
ARMv7 also mandates a hardware floating point unit, which has ABI and performance
impact."
"In 2009, some manufacturers introduced netbooks based on ARM architecture CPUs, in
direct competition with netbooks based on Intel Atom. According to analyst firm IHS
iSuppli, by 2015, ARM ICs are estimated to be in 23% of all laptops."
