Hi!
I´m currently writing a PIC code for a PI detector, but I´m not sure what schematic to use.
I´ve bin looking at Stuart´s PI so far.... but there might be others that is better.
The code I´m workin on gives this abilities:
* 1-16kHz in steps of 1kHz (16 steps)
* pulsewidth of 30-180us in steps of 10us (16 steps)
* waittime after pulse: 10 or 15us
* scantime: 10 or 15us
* calculated afterwait to fit frequency
* doublescan 100us after the first scan
* LED to indicate if frequency is override
The PIC I´m workin on is a 16F877@20MHz, but I intend to convert it for a 16F84@20MHz aswell.
Is this of interest?
Plz give me your thougts about timing etc, and is Stuart´s PI the best to use?
