[Lcdproc] lcdserializer problems

[Christian Kruft]

Hey,

I've completly rewritten Tom Coonan's lcdserialzer code  to make it work 
on a PIC16F873 using hardware UART (with 9600 bauds) and interrupts. The 
LCD is only connected with 4 bits and I'm checking the R/W port to see 
if the display is busy. His windows Tool LCDSerializer is working fine, 
explode, marquee and so on without problems. I can also send commandos 
and strings from the linux console.

echo -ne '\xFE' > /dev/ttyS0    (cmd mode)
echo -ne '\x01' > /dev/ttyS0   (clear display)
echo -n just testing my asm > /dev/ttyS0      (show "just testing my 
asm" on LCD)

all ok until here but lcdproc doesn't work :(

I think the init isn't correct - only garbage appears on LCD. I've 
tested the 0.5.0, the CVS and the patch from here 
http://wiki.ilc.pd.it/ilc_wiki/LcdprocSerial.
What might be the problem? Some timings or a 4/8 bit issue? Don't know 
about coding in C, so I can't play with the source.

When working, I'm going to make the new ASM public.

Greetings, Christian
