LCD4884 and serial communication.

@Oliver,

Thanks for the reply.
just one step closer to the sollution.
serial monitor mirrors now the good charater but how do I get this to get it works with the lcd?
See the code

#include "LCD4884.h"

int val = 0;
char string[10];
char teststring;

void setup() {
  lcd.LCD_init();
  lcd.LCD_clear();
  lcd.backlight(OFF);
  Serial.begin(9600);
}

void loop () {
    while (Serial.available() == 0);
    val = Serial.read();
    Serial.println((char)val);
    itoa(val, string, 10);
    
    lcd.LCD_write_string(0, 0, string, MENU_NORMAL);
  delay(100); 
}
