when i reach reasonable point, i'm going to do so, I just want with this
discussion first to be sure what i'm goin

I'm feeling dense today...a PC parallel port wire's fastest speed
is ~2.7MHz with no wait state mode, so you couldn't operate
at full speed talking to a SPI bus of a microcontroller...

Dear all,
Hi John,
Larry got my idea, he interprets it correctly.
Hi Larry,
Thank you very much for your answer, actually before starting the prototype,
i have the idea of using drivers source code, but i think about the
following scenario, if the hardware designer want to simulate his hardware

I'm not sure what the parallel port does i

Dear all,
I have an idea of a project, but actually i'm software developer rather than
hardware designer, so i need you to help me to figure out the usability of
it, my idea in short focus on the circuit designed to work wih computer e.g.
computer prephierals.
I need to provide a method to simulat
