1. Introduction 

main screen Pabilo is short for Palm Bike LOg. It is a logging program for the Palm platform that can mainly be use for logging and graphing your bike trips.

Pabilo is Filipino for speed or acceleration comming from the Filipino word Pabilisin and for this project short for:

PalmBikeLOg

The name came to me in a flash and I discovered on the internet that it actualy meant something in Filipino and gues what .......... It matches the applications function!

1.1 Changes

In version 1.0 I used the hotsync signal pin with a sensor on the wheel (I still have the old sources on special request). This worked O.K but had a maximum speed of 64 km/h. This restriction comes from the way the event handler works in Palm OS so I thought of someting else.

I build a pice of hardware (realy simple) using an ATMEL AT90S2313 controller running at 11.059200 MHz. And wrote a piece of assembly so the ATMEL controller can measure the time between every wheelround. The Palm requests the last measured time and the total wheel-rounds and displays these values and storing them in some Pabilo Database for later use.
