Hi everyone,
For a change, I don't have a problem - I just thought I'd unleash some
potentially useful code.
Awhile ago I wrote a driver for a HD44780 LCD attached to my ts7260
board. The display is connected as per the Technologix
recommendations. I've been testing it for awhile and it all seems
ok, with the following exceptions :
1) The lcd backlight is not functional (the 5v supply in the ts7260
doesn't have the grunt required for most backlights) so don't connect
it up!.
2) I've only tested it on a 20x4 display, but theoretically should
work with all others of smaller size (not a 40x4 as these are quite
different and use multiple hd44780 controllers)
3) I have some code also for a 4 x 4 keypad which is attached to a
configurable serial port. This is because there is no space for a
keypad scanner on the implementation I'm using (I use the keypad I/O
for other things).
I have only written and tested the driver for lcdproc-0.5.0,
(lcdproc-0.5.3 is the latest) I haven't uploaded the driver to the
lcdproc dev list, because I thought it best for other TS-72xx' users
to use it first. The lcdproc development stream doesn't really
consider non-x86 targets much.
anyway, I'll upload a patch file for lcdproc-0.5.0 and if anyone is
interested, download lcdproc-0.5.0.tar.gz from
http://lcdproc.org/download.php3 and patch with
lcdproc-0.5.0-hd4478-ts7200.tar.gz in the files section of this group.
I'll probably try to migrate the patch to lcdproc-0.5.3 soon.
Cheers
Kym
