Python example char_lcd_plate.py is working perfect.
But I would like to manage it with Pi4J.
I copied bits from python example
LCD_PLATE_RS = 15
LCD_PLATE_RW = 14
LCD_PLATE_EN = 13
LCD_PLATE_D4 = 12
LCD_PLATE_D5 = 11
LCD_PLATE_D6 = 10
LCD_PLATE_D7 = 9
Java:
LCD lcd = new I2CLcdDisplay(2, 16, 1, 0x20, 0, 15, 14, 13, 9, 10, 11, 12);
lcd.clear();
lcd.write(0, "111 ");
lcd.write(1, "222");
Init is fine but I have blue boxes on the screen and no any updates. Any advice?
Update 1
import com.pi4j.component.lcd.LCD;
import com.pi4j.component.lcd.impl.I2CLcdDisplay;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class Display {
@Scheduled(fixedRate = 30000)
public void test() throws Exception {
LCD lcd = new I2CLcdDisplay(2, 16, 1, 0x20, 0, 15, 14, 13, 9, 10, 11, 12);
lcd.clear();
lcd.write(0, "111 ");
lcd.write(1, "222");
}
}
