pulse width meter

This is a project, based on a PIC microcontroller, that measures pulsewidths, calculates duty cycle, and displays to a 2 line LCD display. Available here are schematics, source code, and eventually board files.

This meter displays and is accurate to .1ms, and is able to measure pulses as short as .2ms, and as long as 30ms.

This project is released under the GNU GPL, a copy of which can be found here.

The essence of this license is that the design is freely available, and may be freely distributed, as long as any improvements that any individual makes are also freely available. Group purchases and commercial use are permitted and encouraged, as long as improvements to the design or software are also made publicly available.

Available below are Protel schematics, jpg schematics, and the PIC source.
