Hi Mr. Mz,
after having a look to 93LC86-Datasheet I do not see a problem. The self-timing programming cycle of this Chip avoids timing problems; the rest is only logical stuff.
If you need more general info, how to use the parallel port, I recommend: http://www.jaxelson.@lvr.com/ or
in case you need an example of SPI-Interface in LabVIEW with paraport - then write to: werner.hasche@web.de
You are welcome
regards
wha
