stefanN Posted January 11, 2005 Report Share Posted January 11, 2005 I connected a Nokia Display pcd5844 to my Core module.all connectoins are tested and correct. Voltage is 3,1 V but I used a 10uF capacitor instead of the 2,2 uF. Then I changed the LCD Type to 7 using change_id_v1_4 and loaded the pcd5844 example app. But now the display shows nothing. Does anyone now, what could be wrong? Quote Link to comment Share on other sites More sharing options...
TK. Posted January 13, 2005 Report Share Posted January 13, 2005 Hi stefaN,at the beginning an important info: only the pcd5844 example app contains the driver, this means that you have to copy the app_lcd.inc file into other applications when you want to use them together with the display.The example application also sets the LCD type to 7, so a wrong configuraton cannot be the problem. How did you test the connections?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
stefanN Posted January 13, 2005 Author Report Share Posted January 13, 2005 thanx for this information, so I can be shure that it's no software related problem.I tested the Voltage at the display and I checked, if there are 220Ohm between the pin of the Display and the corresponding pin of the PIC. Perhaps I have the wrong display?I bought a Display for a Nokia 3310, I don't think there aredifferences.So I'm going to check all connections, voltages, resistors...again.I would be verry pretty if I get this display working, because it's not only cheap but also extrem flat, small, nice...

stefanN Posted January 15, 2005 Author Report Share Posted January 15, 2005 Now I'm shure, that I've the wrong display. I tested it with anothher core modul and it didn't work either. Furthermore the additional four pins are missing. And now the glas is broken anyway. So I'll try to get a complete 3310 instead of only the display. Or can somebody tell me, where to order a compatible display in Germany? Quote Link to comment Share on other sites More sharing options...
Screaming_Rabbit Posted January 19, 2005 Report Share Posted January 19, 2005 Furthermore the additional four pins are missingWhat do you mean with that? Which additional (compared with?) pins?Does it look like this one?http://www.myplace.nu/mp3/images/nokia_lcd_large.jpgGreets, Roger Quote Link to comment Share on other sites More sharing options...
stefanN Posted January 21, 2005 Author Report Share Posted January 21, 2005 i mean the four unused pins which you can see on the wiring diagramm at the MBHP_LCD page. Yes, it look's like the one at myplace.nu but instead of the tape there is a metal frame around it.Tomorrow i'll get another used NOKIA phone. Perhaps it has the right display.

Screaming_Rabbit Posted March 6, 2005 Report Share Posted March 6, 2005 Thanks - I've added the link to the MBHP_LCD pageBest Regards, Thorsten.... thanks.Thorsten, could you also change the driver "title"? - I think it's realy called "PCD8544" and not "PCD5844"... this leaded to confusion in earlier posts.Greets, Roger Quote Link to comment Share on other sites More sharing options...
TK. Posted March 7, 2005 Report Share Posted March 7, 2005 Hi Roger,thank you for turing this out (one year after the release ;-)everything but the photo is renamed now (I've to create a new one)Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
