Hope you have fun with it.
It would be a nice in-dash for something... throw in some cap-sense buttons with LED backlights and be set.

No arguments from me.

Happy coding!

You need 192KB ram?
Not sure what to say.

I need most readable code I can afford with as many usability goodies as I can afford.
Here is the current RAM usage report.

As you see, just the engine configurations alone is 5K. Histograms is a utility for performance monitoring, a lot of RAM is used for logging buffers. I have 192Kb at my disposal and I am putting them to use. Simple code => faster rate of change => more features.

Can you have an ECU with 32Kb? Absolutely. Would you get way more comfort with 192Kb? For sure.

Hercules RM42x LaunchPad is ARM-R4 - not ARM-M4

Theoretically it might be more suitable for more hardcore real-time stuff, but with only 32Kb of RAM we would lose all the simplicity of the programming style we are currently enjoying with our 192Kb of RAM. Oh, we would also lose ChibiOS

Let's face - internal combustion engines are slow appliances, it's not rocket science we are taking care of here.

But i´m good at searching and i have ideas , not always good ideas .
We have a position of PR director open. In this role you would be responsible for searching for volunteers who would dare to solder & run rusEfi

The plan is to use a bluetooth module. Hc-06 seems to be easiest to configure. At some point we would need to find it's physical layout so that we can solder them right to our pcb

I might volunteer for the PR position, if someone ports the code to run on this.

Not quite as 'cool' as the STM discovery board, but cool nonetheless as its a dual-core, real-time oriented, ARM-M4 running both cores "lock step", as in both run the same code for error / fault checks and has ECC memory and other fault-tolerant considerations.

My MAP adapt board is also compatible with it.

I'm working through figuring out how to use one of these

I just received.

... for free.
$118 does not work for me. Tell me about the free option

But seriously - since not everyone would be able to get it for free, we should probably look somewhere else. Like bluetooth + cheap Android tablets + Android Dash software

They're not free any more.
But if you think $118 is too much, check Mouser: $365.

Part of the reason I posted the link to Noritake was, besides the free thing, is that after the first 'free sample' I applied for I received an email about another sample offer... and another... and another. The third one is how I received the 'big' display (it's over 12" wide).

And I thought people working on car-oriented things might like a display.

I have this one ,serial board interface will i be able to use it?

Yep, that's exactly the thing I was looking for! Yes, I think we should use character displays via SPI as one of the options of data output. Now question is who would implement this

Think of it more like 'multiplexed' UART.
Route UART TX/RX to several pairs of transistors and selectively enable pairs of transistors to send the signals to whatever device.
Much like how SPI devices support 'chip enable' or 'chip select' lines.
Either way that's some twisted stuff.

I've made an impulsive purchase of http://www.ebay.com/itm/200984980018 - mostly for the SPI module. I am pretty sure the module should be available separately but I could not find it right away.

If all you wanted was the SPI/IIC/I2C module, http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_nkw=display+SPI+module&_sop=15
