Just a heads up that the rayer_spi module wont work with a buffered xilinx
DLC cable. There is a pull down buffer in the MISO ( Data In ) line which
is enabled when pin 6 of the parallel port is pulled low.
I dont have time to be submitting patches, fix it or not I dont mind.
These are the changes I made.
static int rayer_pulldown_bit = 4;
val = 1;
lpt_outbyte &= ~(1 << rayer_pullup_bit);
lpt_outbyte |= (val << rayer_pullup_bit);
Cheers, hope it will help stop someone else spending hours debugging
something that doesn't work.
