4 LCD's an Arduino ?

volvodani:

prog_char* Loks[61] PROGMEM ={"-------","Adler","AE3/6","AE 8/14"........};

prog_uint16_t Adressen[61] PROGMEM ={0,78,6,24,1,3,36,5,10,17.........};



Ich glaube es ist so Richtig.

Leider funktioniert das so nicht , wenn ich PROGMEM dazu schreibe , erscheint keine Lokbeschreibung auf dem Display
Im Programm übergebe ich die Daten an eine Variable

LCDText[0]=String(Loks[4];  // in dem Beispiel wäre das AE 8/14

//diese wiederum wird dann später ans LCD geschickt

lcd[1].print([0]);

Ich weiß nicht mehr weiter !

Hab jetzt nochmal mit PROGMEM in einem Extra Sketch experimentiert , hier funktioniert es ,
Wenn ich das aber in meinem eigentlichen Sketch einbau ,geht's nicht !

#include <EEPROM.h>
#include <avr/interrupt.h>
#include <avr/io.h>
#include <LiquidCrystal.h>
#include <avr/pgmspace.h>

  LiquidCrystal(23, 24, 25, 29, 30, 31, 32),
  LiquidCrystal(23, 24, 26, 29, 30, 31, 32),
  LiquidCrystal(23, 24, 27, 29, 30, 31, 32), 
  LiquidCrystal(23, 24, 28, 29, 30, 31, 32)};
