Hi all,
as promised here is a patch that should speed up the SPI
communication. The idea is quite simple:
The gets in ppi_set(), ppi_clr(), ppi_toggle() and ppi_setall() are
substituted by reads from shadow variables.
I know that the "enum" does belong in the header-file, but I thought
it is better to leave it there, until someone has tested the patch.
I still haven't got a parallel programming cable, so I can't test it
myself.
