Hallo,

versuche schon seit mehreren Stunden ein Pollin LCD ( http://www.pollin.de/shop/shop.php?c...OTg4OTk4&ts=20 ) zum laufen zu bekommen..

Leider ohne erfolgt

Bevor ich lcd_init(LCD_DISP_ON); aufrufe, zeigt das Display einen Balken in der zweiten Zeile..

Danach leider nichts mehr..

Bei lcd_puts("Hello world."); bleibt das Display ebenfalls leer.

Meine lcd.h:
Code:
#define XTAL 16000000              /**< clock frequency in Hz, used to calculate delay timer */


/**

 */
#define LCD_CONTROLLER_KS0073 0  /**< Use 0 for HD44780 controller, 1 for KS0073 controller */

/** 
 *  @name  Definitions for Display Size 
 *  Change these definitions to adapt setting to your display
 */

#define LCD_WRAP_LINES      0     /**< 0: no wrap, 1: wrap at end of visibile line */


#define LCD_IO_MODE      1         /**< 0: memory mapped mode, 1: IO port mode */
#if LCD_IO_MODE
/**
 *  @name Definitions for 4-bit IO mode
 *  Change LCD_PORT if you want to use a different port for the LCD pins.
 *
 *  The four LCD data lines and the three control lines RS, RW, E can be on the 
 *  same port or on different ports. 
 *  Change LCD_RS_PORT, LCD_RW_PORT, LCD_E_PORT if you want the control lines on
 *  different ports. 
 *
 *  Normally the four data lines should be mapped to bit 0..3 on one port, but it
 *  is possible to connect these data lines in different order or even on different
 *  ports by adapting the LCD_DATAx_PORT and LCD_DATAx_PIN definitions.

Habe die Pins und Leitungen schon mehrfach geprüft.

Hat jemand eine Idee wodran es liegen könnte?

Schonmal vielen Dank

PS.: es handelt sich dabei um einen ATMEGA32
