Greatest thing since sliced bread.

Unlike the 16 bit  processors used in Pic (Tracy Crook), Ardunio,
mega-squirt and MicroTech (same as megasquirt).

This 32 bit processor does hardware floating point math.

That makes EFI systems much much much simpler to program. And it is
fast. Same processor type as used in your smart phone. Cheap enough
to use one per injector for ultimate redundancy. The program is much
simpler too.

5 Year olds have learned to program in BASIC. If I can do it any
moron can:)

More on this latter as I am going to use it to control my ignition on
a stock RX8.

I'm missing something on this one. The chip is just a NXP micro + BASIC in code.

So I take a NXP Arm LPC1114 device, load up a basic interpreter.  So now when I write BASIC code,
the processor takes time to interpretate the basic, convert to op codes, and execute the code.
So now a $1.60 part cost $10.00

IEE754 is just the definition.  In this case, it means the BASIC math can handle 2.1 + 3.4 * 4.  There is no Floating Point hardware in the chip, just the usual accumulator functions. The Basic handles the decimal place, but at a cost of time to execute the code.

Compiled Basic would make much more sense for your ignition controller.

Mikroe has a bunch of cool boards, and the BASIC compiler.   They do charge $249 for the ARM basic compiler, just check to see if it support the NXP LPC11xx family parts.  $249 for the compiler,
much cheaper IC's, and that will run must faster.

Nice thing about the Microchip stuff (PIC32) is their integrated debugger is free to download, doesn't expire.  It you want to optimize code, you have to buy the "upgraded optimizer" to get better code density.  For home hobbyist just use a bigger memory chip (512K flash, versus 256K flash). If I was selling 100K units, I'd buy the compiler in a heart beat to save $0.40 on each chip.  In our case, just pay the extra and use the free compiler.   The free tools are "C" based, but your could buy the Mikroe Basic Compilier, too.

  They claim it is a  compiler.


I am thinking of doing a pc board for this chip with a Arduino style "shield" interface.
The shields will be stackable. Are you interested?


BTW I got a Mikroe ARM board and Basic compiler if you are interested.
It is a little overkill for what I want to do with it.
