Wiring LCD I2C Ke Raspberry Pi Pico #

– connect the GND of the display to a GND (ground) pin (black cable)
– connect the VCC pin of the display with a 5V pin (red wire)
– connect the SDA pin of the display to GP0 (grey wire)
– connect the SDC pin of the display to GP1 (yellow wire)

Sample Code #

from machine import Pin, I2C
from lcd_api import LcdApi
from pico_i2c_lcd import I2cLcd

I2C_ADDR = 0x27
I2C_NUM_ROWS = 2
I2C_NUM_COLS = 16
i2c = I2C(0, sda=machine.Pin(0), scl=machine.Pin(1), freq=400000)
lcd = I2cLcd(i2c, I2C_ADDR, I2C_NUM_ROWS, I2C_NUM_COLS)

lcd.backlight_on()
lcd.putstr("Great! It Works!")
lcd.move_to(3,1)
lcd.putstr("khurslabs.com")
