Hi!. I built this frequency counter with a PIC:
www.qsl.net/om3cph/counter/lcd/contribs/images/schema1.gif
I would like to log the readings on my PC. It has a parallel port, I thought about connecting it to the 7 lines between the PIC and the LCD. Looking at the waveforms there, shorter pulses are 1us wide. The PIC takes 10 measurements per second. The interfase is 4 bit, and uses the R/W line.
Did anyone do anything similar?. I wouldn't care having to use x86 ASM and/or booting the PC in DOS to avoid colliding with Windows administration.
Thank you!.
