I spent the evening trying to figure out how to get the lcd started and i
finally get some output from lcdproc. It turns out i have to use EPP/ECP
1.7 DMA 1 to get the lcd working.
I'm having some problems with the updates though. The lcd never gets
cleared and old text from old screens never disappears. Sometimes only
half of the characters gets displayed (usually the ones on the right side
of the lcd). What i mean is that character 1-10 doesn't get updated but
character 11-20 do.
Also writing the text to the lcd is quite slow. You can see the text
getting written from left to right.

Does anyone have any ideas?



Some info

Modules: parport, parport_pc and ppdev loaded
lcdproc version: 0.4.5
Wiring: winamp

DelayMult=1 (tried 2 (gives no output), with 4 (no improvements))
DelayBus=true (with this set to false i get no lcd output)
