PC+LabView = Power/Speed/HR logging software
Hi guys, I'm not sure if someone has posted something like this here before. I wrote a little program to connect my bike computer sensor and heart rate monitor to my PC. All it requires is the magnet and sensor from a bike computer and a PC with a printer port. (The Heart Rate and Power logging requires some other equipment - see the readme for details). The program requires National Instruments LabView to run. I think they have a demo available on their website for you to try out.
See the following post to download my program
'Homebrew' Roller Racing Set-ups
I used LabView just because it is easy to make realtime charting/graphing software. The guts of the program are a simple tachometer that reads pulses from the magnet sensor and converts pulse rate to speed. The heart rate receiver works the same way.
