PC => FPGA, Parallel Port Communication

[Rodrigo Ribeiro]

Hi,

Does anybody have an example of a bidirectional communication protocol
between the parallel port (EPP Mode) and the FPGA?

I need to work with digital image processing on the FPGA and need to
estabilish this communication to transfer data from the PC to be
processed on the FPGA.

I work with Quartus II Web Edition and a Altera Cyclone.


Thanks.

Why on earth, in 2007, are you using a parallel port?

You would be better to use a fast transfer media like USB, ethernet, FireWire...

Hi

I'm using a XESS XS40 board that has parallel port communication with
the PC. For a little design that I made, I have a little example of
unidirectional communication (PC to FPGA Board). Maybe you can adapt
it or modify it to be bidirectional and improve it.

If you are interested, e-mail me.
