Hei, I'm using a 40x4 LCD I took CVS and put controllers=2 in conf file... Result: Blank LCD.. nothing at all. With the old lcd4linux I got 2 rows out of 4.. Btw, how should I write in conf file when I have Enable 1 on pin 17? I'm using the same display on ELMP, so wouldn't want to rewire it. ----- Original Message ----- From: "Michael Reinelt" <re...@eu...> To: "Stefan Krister" <ste...@cr...> Cc: <lcd...@li...> Sent: Thursday, August 21, 2003 7:45 AM Subject: Re: [lcd4linux] 40x4 display with HD44780 > >>There are large (40x4) displays which internally constist of two > >>HD44780 chips, with two seperate "Enable" lines.

Hi Joachin, > I'm using a 40x4 LCD > I took CVS and put controllers=2 in conf file... > Result: Blank LCD.. nothing at all. > > With the old lcd4linux I got 2 rows out of 4.. Hmmm... I don't have such a large display. My smaller ones do work correctly. But there was a bug in the changed parallel prot code, which I have fixed. Could you please try again? At the moment there's a problem at sourceforge with their anonymous CVS access. Anonymous access is routet to their backup servers, which are updatet with a 24 hours delay only. This means, if I commit a bugfix, it may take up to 24 hours until anybody else sees this change. This is very annoying.... Anybody has a hint for a workaround? So please double-check if your "parport.c" is "v1.6", otherwies you got the old version. > Btw, how should I write in conf file when I have Enable 1 on pin 17? > I'm using the same display on ELMP, so wouldn't want to rewire it. Pin 17 is "SELECT", therefore you should write Wire.Enable "SELECT" btw, what is ELMP? bye, Michael -- netWorks Vox: +43 316 698260 Michael Reinelt Fax: +43 316 692343 Geisslergasse 4 GSM: +43 676 3079941 A-8045 Graz, Austria e-mail: re...@eu... |

Thanks a lot for testing! I'm working on the icon and heartbeat stuff, which will probably not make it into 0.9.11 (this is quite complicated stuff), and Patrick is working on the liblcd4linux. Things have to settle down a bit... bye, Michael -- netWorks Vox: +43 316 698260 Michael Reinelt Fax: +43 316 692343 Geisslergasse 4 GSM: +43 676 3079941 A-8045 Graz, Austria e-mail: re...@eu... |
