We recently had a customer write us with an interesting problem: He wanted to use our SSI object to drive a MAX7219 IC — an LCD segment display. However, he could not seem to be able to make it work.

Our resident support guru, Andrew, is not one to turn down such a challenge. He first started with a simple test using IO banging. Once that worked, the next step was implementing SSI; that was actually very simple, and the code runs about 270 times (!) faster.

Finally, Andrew wrapped it all up in a ZIP, and now you can just download the demo project and try it out yourself. Enjoy!
