Atmel 8535 for engine management - Genesis

[Bernd Felsche]

Howdy,

I've started documenting the design ideas for an AVR-based ECU to
"replace" a Volkswagen Digifant unit. Tha aim is a unit which is not
only a plugin replacement, but also one which is expandable and can
take advantage of better sensor technology.

A large proportion of the design provides for communicating with
"slave" chips; initially an Intersil knock chip and another AVR in a
"head unit" for tuning, data logging and display.  Several "spare"
chip select lines are as yet to be reserved for other possible
slaves.

Note that this is completely untested and liable to change markedly
before a working prototype is built. Hence the "vapour" :-)

I'll be adding more information about allocation of internal chip
resources (timers, etc) later.

URLs for references will also fester.
