eb500 and Javelin code samples

jmstepanek

Does anyone have any code samples showing how to use the eb500 and the Javelin together? Are they posted somewhere and I'm just not seeing them?

Thanks,

Yes here is a class I was playing around with last year. Have fun!

Thanks, TimC.

That was a very quick reply. This code sample should be very helpful.

Thanks again.
