Nice find Vasi, but I think the Maximite firmware will be designed to run on its own board, especially considering the VGA output. I read the Maximite uses one of its serial controllers as a VGA controller. The core writes a page of graphic data to the serial controller, and the controller then processes the data to the VGA port, freeing the core to continue processing the program. Very clever, means a rock steady VGA output and the core is free to do other things.
I've been working on the Watt/RPM plotter, I should really start a new thread for this, but anyway, the interface is built and today I tested some of the basic program functions. I'm using a old servo motor as the alternator, driven by a drill.
Here's a screen shot after a test run, you can see the power curve.
I need to find a better way to take screen shots. My old VGA monitor died
, but I'll have a look and see if I can fix it.
The plot is built up as you test, and at the end of the test it joins the dots together to make a curve. Its very crude at this stage, this was just a test to see if the Maximite would read in the values quick enough. It did.
