**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

![A](https://user-images.githubusercontent.com/34527010/106843779-cc86e780-66e1-11eb-8c48-b3e2f6f84fa6.PNG)

Step 3: Save the library file into the Pi Pico

Click OK and the library is added to your Pi Pico

## Import LCD_SPI Library

 - Import LCD_SPI library

 

 `from LCD_SPI import *`

## Import LCD_I2C Library

 - Import LCD_I2C library

 

`from LCD_I2C import *`

## 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() `
