The first version of the Chee-dar code that will be used when I can. It has logging set up to record speeds over 25 MPH, and saves the highest speed detected. Prebuilt jar is in the release. If you have Limpkin's CDM324 with an expansion board, make sure it the only serial device plugged in, and brltty isn't eating your USB connection. (uninstall brltty if you have it)
