Hello everybody!

I'm currently involved in a project building a highly efficient 1-cylinder 4-stroke engine. We are currently concentrating on improving the timing on the injection as at the moment it does not vary with engine speed, and as a result is wasting a lot of fuel. We have decided to use either an AVR of 8052 to do the controlling and 'thinking'. Getting a microcontroller to act as a timer is a fairly easy task, and this application will barely load the controller, so we want to use it to carry out other tasks too, such as servo control of the brakes and choke iris, data logging, communication (to an off-board laptop), and communication with the electronic controls on the steering wheel (we're using an F1 like steering wheel).

For various reasons we want to be able to add and take away various features of the control firmware, and think that a multi-tasking OS running seperate tasks for each feature would be the best approach. My question is, does anybody have any experience in writing multi-threaded programs for the 8052 (or AVR) who could give me some pointers as to where to start?

Thanks for any help you may be able to give!

Matt.

P.S. Hello Steve (Taylor), long time no see! How ya doing?
