Linux Speedometer, Odometer, and Trip Computer |
PIC Microcontrollers Electronics Linux C Programming |
Implemented on a 386/25 8Mb DECpc laptop, this Linux application
attaches to a PIC 16F84 microcontroller which is then attached to a
vehicle speed sensor. The program displays current speed, distance
travelled, and allows the marking of waypoints and the calculation of
distance to the next town.
Update: adjustments for higher sampling rates, and a schematic
contributed by a reader.
