If you are using a microcontroller to interface with the JHD-2x16-I2C display, you will need to write code to send I2C commands to the display. Here's an example code snippet in C:
This code initializes the I2C interface and sends initialization commands to the JHD-2x16-I2C display. It then prints the string "Hello, World!" to the display. jhd-2x16-i2c proteus
void lcd_print(char *str) // Send I2C data TWDR = (I2C_ADDRESS << 1) If you are using a microcontroller to interface
#define I2C_ADDRESS 0x27
int main() lcd_init(); lcd_print("Hello, World!"); return 0; // 100 kHz TWSR = 0x00
void lcd_init() // Initialize I2C TWBR = 0x18; // 100 kHz TWSR = 0x00;
