The HD44780U has pin function compatibility with the HD44780S which allows the user to easily replace an LCD-II with an HD44780U.

Profis kennen das Problem mit LC-Displays, der Hersteller schreibt zwar das das LCD zu einem mit HD44780-Controller kompatibel ist, aber leider sieht die Realität anders aus. Da viele Compiler auf HD44780-Librarys zurückgreifen kommt es sehr häufig vor das das LCD Dinge macht die man eigentlich gar nicht

Das LCD und sein Controller. Die meisten Text-LCDs verwenden den Controller HD44780 oder einen kompatiblen (z. B. KS0070, ST7066U) und haben 14 oder 16 Pins. Hier ist die häufigste Anschluss-Belegung angegeben. Pin # Bezeichnung Funktion 1 Vss GND (beim TC1602E Vdd=Vcc) 2 Vdd/Vcc

Dazu muss man wissen, dass das Problem nicht die Versorgung des Controllers auf dem LCD-Modul (der HD44780 ist ab 2,7V spezifiziert), sondern die Erzeugung der Kontrastspannung für die Anzeige ist. Selbst wenn man den Kontrastpin auf Masse legt, ist unterhalb von etwa 4V nichts mehr zu erkennen. Dies führt
meist einfach mit einem Mikrocontroller ansteuern. Text (character) LCDs verwenden meistens den HD44780 oder einen kompatiblen Controller (z.B KS0066). Das KS0066 Timing und die Init-Sequenz weichen stark vom Timing des HD44780 ab! Es gibt gute Application Notes zu Displays (mit KS0066) von Hitachi.
Bei einem HD44780 kompatiblen LCD kann man, in sehr begrenztem Rahmen, auch eigene Zeichen entwerfen und anzeigen. Das Display verfügt über einen kleinen RAM-Speicher, den sog. Character Generator RAM (CG RAM), in
Verwirrung vorzubeugen: Häufig wird die Größe der Zeichen mit 5x7 Pixeln angegeben, und nicht 5x8. (Im HD44780-Datenblatt von Hitachi ist immer von 5x8 Pixeln die Rede.) Tatsächlich werden für die meisten Zeichen wirklich nur 5x7 Pixel verwendet, um die unterste Zeile für den Cursor benutzen zu können. Im
trying to init display for 2 days but without any success..I assembled another display with driver hd44780 and worked like charm.. I searched and read almost all threads dedicated to EA Dogs here.All i got some errors or compiled programs with no effect to display.. The problem is i didn't handle the
damn,Ea dog is going to the trash !!I destroyed it :) I just connected display (the Hd44780) and it works with a code for ea dog :) Unbelievable.

Hi, I want to control a HD44780 display with a PIC 18F2550 via a 4bit interface, but my routine doesn't seem to work. I've already looked on several pic sites but I just can't find my mistakes. So if someone could look over it,
Which Compiler are you using? MCC18 Compiler from Micrchip is shipped with a library for the hd44780. You only had to: #include xlcd.h There must also be a docu somwhere. Otherwise just look in the Header itself.
