LCD Display am Schieberegister

Hier ein Sketch zum Display testen für meine Wetterstation:

// 2-wire connection to a HD44780-compatible LCD via shiftregister with:
//   Data (and Enable) on Arduino pin 12
//   Clock on Arduino pin 13
//
// Shiftregister bits #0 - #1 - not used (bit #0 must be set to zero)
// Shiftregister bit  #2 - connects to LCD RS (Register Select)
// Shiftregister bits #3 - #6 on LCD data inputs D4-D7.
// Shiftregister bit  #7 - used for enabling the Enable puls.
// LCD R/!W (or rw) hardwired to GND (write to LCD only, no reading from)
//
// USAGE: ShiftRegLCD LCDobjectvariablename(Datapin, Clockpin, Enablepin or TWO_WIRE [, Lines [, Font]]])
//   where Lines and Font are optional.
//     Enablepin: can be replaced by constant TWO_WIRE, if using only 2 wires.
//     Lines: 1 or 2 lines (or more if possible)
//     Font : 0 or 1, small or big font (8 or 10 pixel tall font, if available).

#include <ShiftRegLCD.h>

ShiftRegLCD srlcd(8, 9, 7,2,1);

void setup()
{
  // Print a message to the LCD.
  pinMode(10,OUTPUT);
  analogWrite(10,128);
}

void loop()
{
  showValues(); 
  delay(5000);
}


void showValues() {
  srlcd.setCursor(0, 0);
  srlcd.print("IN: ");
  srlcd.print(random(19,22));
  srlcd.write(223);
  srlcd.print("C   ");
  srlcd.setCursor(10, 0);

  srlcd.print("R ");
  srlcd.print(random(10,25));
  srlcd.print(" mm ");
