Moduł I2C DH44780

[mati12_14]

Spoko,wiecej mi nie trzeba. Wgraj skecz hello world jeszcze raz na adres 0x27 w takim wypadku.Najlepiej jak wpiszesz tamte polecenie deklaracji wyswietlacza bo napewno dziala na taki konwerter jak masz. W setup dopisujesz jeszcze lcd.backlight(); i powinno byc spoko. Jak bedzie migac wyswietlacz to odpal monitor szeregowy. Czasem to pomaga na resety. Nie bede tlumaczyl dlaczego bo sam srednio wiem. Jesli zadziala to pomyslimy co dalej z tym fantem zrobić. Teoretycznie wiem,ale w praktyce otwarty port za bardzo mi nie przeszkadza w testowaniu.

to jest ten kod po dopisaniu nie da się wgrać

#include <Wire.h>
#include <LiquidCrystal_I2C.h>



#define BACKLIGHT_PIN 13

LiquidCrystal_I2C lcd(0x27); // Set the LCD I2C address

//LiquidCrystal_I2C lcd(0x27, BACKLIGHT_PIN, POSITIVE); // Set the LCD I2C address


// Creat a set of new characters
const uint8_t charBitmap[][8] = {
{ 0xc, 0x12, 0x12, 0xc, 0, 0, 0, 0 },
{ 0x6, 0x9, 0x9, 0x6, 0, 0, 0, 0 },
{ 0x0, 0x6, 0x9, 0x9, 0x6, 0, 0, 0x0 },
{ 0x0, 0xc, 0x12, 0x12, 0xc, 0, 0, 0x0 },
{ 0x0, 0x0, 0xc, 0x12, 0x12, 0xc, 0, 0x0 },
{ 0x0, 0x0, 0x6, 0x9, 0x9, 0x6, 0, 0x0 },
{ 0x0, 0x0, 0x0, 0x6, 0x9, 0x9, 0x6, 0x0 },
{ 0x0, 0x0, 0x0, 0xc, 0x12, 0x12, 0xc, 0x0 }

};

void setup()
{
int charBitmapSize = (sizeof(charBitmap ) / sizeof (charBitmap[0]));

// Switch on the backlight
pinMode ( BACKLIGHT_PIN, OUTPUT );
digitalWrite ( BACKLIGHT_PIN, HIGH );

lcd.begin(16,2); // initialize the lcd

for ( int i = 0; i < charBitmapSize; i++ )
{
lcd.createChar ( i, (uint8_t *)charBitmap[i] );
}

lcd.home (); // go home
lcd.print("Hello, ARDUINO ");
lcd.setCursor ( 0, 1 ); // go to the next line
lcd.print (" FORUM - fm ");
delay ( 1000 );
}

void loop()
{
lcd.home ();
// Do a little animation by writing to the same location
for ( int i = 0; i < 2; i++ )
{
for ( int j = 0; j < 16; j++ )
{
lcd.print (char(random(7)));
}
lcd.setCursor ( 0, 1 );
}
delay (200);
}

Sprawdź ten:

Kod:

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);  // Ustawienie adresu ukladu na 0x27

void setup()
{
  lcd.begin(16,2);               // initialize the lcd
  lcd.backlight();
  lcd.home ();                   // go home
  lcd.print("Hello, ARDUINO ");  
  lcd.setCursor ( 0, 1 );        // go to the next line
  lcd.print (" FORUM - fm   ");
  delay ( 1000 );
}

void loop()
{
}

Wgrywa się jest ok ale zegara nadal nie mogę wgrać

[mati12_14]

Może po prostu coś jest źle w kodzie zegara.Najpierw wgraj sam przykład zegara i zobacz czy działa. Jeśli zadziała to zmodyfikuj swój kod.

Możesz zerknąć na ten kod

const char *monthName[12] = {

"Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
};

void setup() {

lcd.begin(16, 2);

lcd.setBacklight(HIGH);
