It operates in Master Transmitter mode, meaning data is sent from the microcontroller (master) to the LCD module (slave).\n\nMain Features:\n\n- Control LCD via I2C\n\n- Display text on LCD\n\n- Clear the screen\n\n- Set cursor position (row and column)\n\n- Use HD44780 controller registers in 4-bit mode\n\nHardware Requirements:\n\n- Arduino Nano / Uno / Mega or any I2C-compatible microcontroller\n\n- LCD 16x2 or 20x4 with I2C interface (PCF8574)\n\n- 4.7kΩ pull-up resistors on SDA and SCL (optional if not built-in)\n\nInstallation \u0026 Usage:\n\n- Copy LCD_I2C.h and LCD_I2C.cpp files into your project folder.\n\n- Include the header file in your main.ino:\n\n      #include \"LCD_I2C.h\"\n    \n      LCD_I2C lcd(0x27); // I2C address may vary, check with an I2C scanner\n\n- Initialize the LCD in setup():\n  \n      void setup() {\n          lcd.LCD_clear();\n          lcd.LCD_setCursor(0, 0);\n          lcd.LCD_print(\"Hello, World!\");\n      }\n\n----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------\n\n**Opis - Polski**\n\nBiblioteka LCD_I2C służy do obsługi wyświetlacza LCD ze sterownikiem HD44780 za pomocą konwertera I2C z modułem PCF8574. Umożliwia komunikację w trybie Master Transmitter, co oznacza, że dane są zapisywane z mikrokontrolera (master) do wyświetlacza (slave).\n\nGłówne funkcjonalności:\n\n- Obsługa wyświetlacza LCD przez magistralę I2C\n\n- Wyświetlanie tekstu na LCD\n\n- Czyszczenie ekranu\n\n- Ustawianie kursora na wybranym wierszu i kolumnie\n\n- Wykorzystanie rejestrów sterownika HD44780 w trybie 4-bitowym\n\nWymagania sprzętowe:\n\n- Arduino Nano / Uno / Mega lub inne kompatybilne urządzenie z I2C\n\n- Wyświetlacz LCD 16x2 lub 20x4 z konwerterem I2C (PCF8574)\n\n- Rezystory podciągające 4.7kΩ na SDA i SCL (opcjonalnie, jeśli nie ma wbudowanych)\n\nInstalacja i użycie:\n\n- Skopiuj pliki LCD_I2C.h i LCD_I2C.cpp do folderu swojego projektu.\n\n- W main.ino dołącz plik nagłówkowy\n\n      #include \"LCD_I2C.h\"\n    \n      LCD_I2C lcd(0x27); // I2C address may vary, check with an I2C scanner\n\n- Zainicjalizuj wyświetlacz w setup():\n\n      void setup() {\n          lcd.LCD_clear();\n          lcd.LCD_setCursor(0, 0);\n          lcd.LCD_print(\"Hello, World!\");\n      }\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkwapisz2000%2Flcd-i2c-library","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmkwapisz2000%2Flcd-i2c-library","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmkwapisz2000%2Flcd-i2c-library/lists"}
