LCM1602A-14 LCD MicroPython Library for Pi Pico

This library supports LCM1602A-14 LCD module I2C and SPI communication with Raspberry Pi Pico.

The library file must be saved inside the Raspberry Pi Pico before uploading user's code

Add Library

Step 1: Download the library file (LCD_SPI.py or LCD_I2C.py)

Step 2: Launch Thonny application and open the library file

Step 3: Save the library file into the Pi Pico

Step 4: Save the library with the same name you downloaded with (LCD_SPI.py or LCD_I2C.py) Must add .py at the back

Click OK and the library is added to your Pi Pico

Import LCD_SPI Library

Create Object for SPI

Create object using the class
Create LCD object with LCD's sck pin connected to PICO's sck pin 2, LCD's sda pin connected to Pico's tx pin 3
Here we use tx, it is same as MOSI for SPI communication

lcd = LCD(sck=2, tx=3, cs=5)

Create Object for I2C

Create object using the class
Create LCD object with LCD's sda pin connected to PICO's sda pin 2, LCD's sck pin connected to Pico's scl pin 3

lcd = LCD(sda=2, scl=3)

Set cursor

Set the cursor to a specific position
First parameter sets the column, second parameter sets the row
Set the cursor to column 0 (first column) and row 0 (first row)

lcd.set_cursor(0,0)

On LCD Display

Turn on the LCD Display without clearing the data
Cursor and Blink is Off by default

lcd.on()

Cursor On, Blink Off

lcd.on(cursor=True, blink=False)

Cursor Off, Blink On

lcd.on(cursor=False, blink=True)

Cursor On, Blink On

lcd.on(cursor=True, blink=True)

Off LCD Display

Turn off the LCD Display without clearing the data

lcd.off()

Write to LCD Display

Write string to the LCD

lcd.write("Hello World")

Clear LCD Display

Clear the data on the display

lcd.clear()

Scroll LCD Right

shifts the whole LCD display one character cell to the right

lcd.scrollDisplayRight()

(only currently implemented in the I2C library because I am lazy)

Scroll LCD Left

shifts the whole LCD display one character cell to the left

lcd.scrollDisplayLeft()
