Dilshan developed a precision event logger based on the PIC16F73 and some binary ripple counters from the CMOS logic family. The project uses a 2Mhz reference clock, and is capable of measuring events from 0.02 to 6.8 seconds long.
The counter gets activate and deactivate in positive edge of the input signal. Thanks to the wider operating voltage of the CMOS ICs this counter may be able to handle +5V to +15V of input signal. At the end of the counter session system release total tick count to the RS232 interface and it can receive through any serial terminal software. When applying the inputs it is recommended to maintain minimum of 100ms of interval between each session.
