Hallo Ich habe das LCD "YL162-90" von Polin das tut auch, nun wollte ich es mit einem ATmega8 ansteuern 4 bitmodus, ich habe dazu die library von http://homepage.hispeed.ch/peterfleury/avr-software.html#libs das "LCD library for HD44870 based LCD's" heruntergeladen und für meine Hardware angepasst nun wollte ich das Testprogramm das dabei ist Kompilieren aber es kommt die Fehlermeldung.: ~/AVR$ make -------- begin -------- avr-gcc (GCC) 4.3.3 Copyright (C) 2008 Free Software Foundation, Inc.

MfG AT90S1200
> ... -o /main.o
Wo kommt der Schrägstrich hier her?
Du hast als normaler Benutzer nicht die Berechtigung ins Root-Directory
zu schreiben (macht auch keinen Sinn, dort die Object-Files zu
platzieren).
AT90SXXXX schrieb: > Fatal error: can't create /main.o: Permission denied Da Du vermutlich als nicht-root Benutzer kompilierst, hast du unter / keine Schreibrechte, und kannst somit keine /main.o anlegen. Da stimmt was im Makefile nicht. Das sollte etwa so ... -o ./main.o oder so: ... -o main.o aussehen Gruss, rweber
Stefan Ernst schrieb: > Wo kommt der Schrägstrich hier her? Ok, ich beantworte das mal eben selber. ;-) Du kannst im Makefile die Zuweisung an OBJDIR nicht einfach auskommentieren. Wenn alles ins selbe Verzeichnis soll, wie die Source-Files, kannst du dort auch ein "." zuweisen.
ich habe im Ordner home eine weiteren ordner AVR und dort sind alle Dateien da sollte er auch alles rein machen warum er dort ein / macht weiß ich nicht wie ich schon geschrieben habe stimmt dort was nicht danke für die schnelle Antwort (-: mfg AT90S1200

/*********************************************************************** ***** Title : HD44780U LCD library Author: Peter Fleury <pfleury@gmx.ch> http://jump.to/fleury File: $Id: lcd.c,v 1.14.2.1 2006/01/29 12:16:41 peter Exp $ Software: AVR-GCC 3.3 Target: any AVR device, memory mapped mode only for AT90S4414/8515/Mega DESCRIPTION Basic routines for interfacing a HD44780U-based text lcd display Originally based on Volker Oth's lcd library, changed lcd_init(), added additional constants for lcd_command(), added 4-bit I/O mode, improved and optimized code. Library can be operated in memory mapped mode (LCD_IO_MODE=0) or in 4-bit IO port mode (LCD_IO_MODE=1). 8-bit IO port mode not supported. Memory mapped mode compatible with Kanda STK200, but supports also generation of R/W signal through A8 address line.

Sorry ich habe das falsch eingefügt habe erst später gesehen das man Dateien auch hoch laden kann hier ist noch die lcd.h und main.c
Diese Zeile in lcd.h ist der Grund für die Fehlermeldungen:

ich habe das nach diser vorlage http://www.mikrocontroller.net/articles/AVR-GCC-Tutorial/LCD-Ansteuerung#Anschluss_an_den_Controller beschaltet nun ist ja RW an GND, was muss ich dan dort: #define LCD_RW_PIN /**< pin for RW line */ eintragen wen das nicht offen bleiben darf? mfg AT90S1200

okay ich habe das jetzt so um gelötet das es PIN konform mit der lcd.h Datei ist. nun es kommt immer ein schwarzer Balken den ich mit dem Kontrast heller dunkler machen kann. ich weiß so langsam nicht mehr weiter mfg AT90S1200
