Hi

Could you help me to fix this code?
I want to print all numbers from 0 to 100 on a single row...
but it doesnt works.

any suggestions?

Code: Select all

#include "Wire.h"
#include "LiquidCrystal.h"

LiquidCrystal lcd(0);

void setup() { 
  lcd.begin(16,2);
}

void loop() {
  lcd.setCursor(16,1);
  lcd.autoscroll();
  for (int thisChar = 0; thisChar < 100; thisChar++) {
    lcd.print(thisChar);
    delay(500);
    }
  lcd.clear();
}

These displays have a 40x2 display buffer. You can't scroll more than 40 characters.

...what do you think if i will clean the buffer evry 40 characters?

It won't be as smooth as the hardware scroll, but it should work. There is a clear() function in the library: http://www.arduino.cc/en/Reference/LiquidCrystal
