Wer kann das Programm umschreiben?
Hat das "neue" Display von dem Typen nicht das gleiche Protokoll wie der HD44780 Controller? Dann kannst einfach so eins anklemmen.
für den AM Eingang an und 45Mhz - 130Mhz für den FM Eingang. Mein Code für LM7001/ATMega88 und HD44780 Display kann ich gerne mal posten, wenn Interesse besteht.

backlight-intensity control, digitalOct 03, 2005 analog converter, DAC APPLICATION NOTE 3658 Serializing an HD44780 LCD Display Besides reducing the number of required GPIO lines from eleven to two, this circuit also provides programmable contrast and backlight control. Most LCD character displays connect to the outside world through a controller IC, such as the HD44780 (Hitachi) or equivalent. That interface has serious drawbacks, however. It uses up a large number of the microcontroller's general-purpose input/output (GPIO) pins, and it isn't capable of providing

Mega8: VQC10 LED-Matrix 5x7 Zeitmultiplex - Bestimmte Bits eines unsigned char auf Ports ausgeben
:) Jetzt wird es Zeit mit denen etwas zu machen! - Sicherlich gibt es einfachere Alternativen wie HD44780-kompatible Displays oder LED-Matrix-Anzeigen mit SPI-Schnittstelle, aber es macht unheimlich viel Spaß diese alten Anzeigen zum Leben zu erwecken! :) Evtl. Ergebnisse poste ich hier im Thread
sodass man den gesamten Zeichensatz darauf darstellen kann. Der 5x7-Font entspricht weitestgehend dem HD44780-Original. Sven

Problem bei LCD-Ansteuerung mit PIC
Hallo hanshorst Ich gehe davon aus, dass Du ein HD44880 kompatibles LCD verwendest. In Deiner LCD_Init vermisse ich die 3malige initialisierung im 8Bit-Modus. Erst dann kann in den 4Bit-modus umgestellt werden. So steht es auch im Datenblatt des HD44780

backlight-intensity control, digitalOct 03, 2005 analog converter, DAC APPLICATION NOTE 3658 Serializing an HD44780 LCD Display Besides reducing the number of required GPIO lines from eleven to two, this circuit also provides programmable contrast and backlight control. Most LCD character displays connect to the outside world through a controller IC, such as the HD44780 (Hitachi) or equivalent. That interface has serious drawbacks, however. It uses up a large number of the microcontroller's general-purpose input/output (GPIO) pins, and it isn't capable of providing
