4.4 TFT

The liquid crystal display (LCD TFT) with around 65,000 colors and a diagonal of 1.8 inches has a resolution of 128×160 pixels and can be controlled via SPI.

It is suitable for displaying colorful graphics and images. Letters and other characters are displayed as graphics made up of many individual dots.

The TFT is connected to the GPIO pins GP17 (CS), GP3 (DC), GP6 (RES) and GP2 (BL).

In addition to texts, rectangles can also be displayed, for example:

ATTENTION! Two separate library files and a font file are required for the TFT display; you can download

the required files here. Then transfer all files from the Libraries folder to the root directory of your

Raspberry Pi Pico so that the folder structure looks like this:

from machine import Pin, SPI

import ST7735

# Initialize LCD

spi = SPI(0, baudrate=8000000, polarity=0, phase=0, sck=Pin(18), mosi=Pin(19),

miso=Pin(16))

lcd = ST7735.ST7735(spi, rst=6, ce=17, dc=3)

backlight = Pin(2, Pin.OUT)

# Turn backlight on

backlight.high()

lcd.reset()

lcd.begin()

# Display content on the LCD

lcd.ll_screen(lcd.rgb_to_565(0, 255, 0)) # Fills the screen with a green color

# Display text

lcd.p_string(20, 50, ‚Hello, World!‘)

# Draw red rectangle

lcd.draw_block(10, 10, 50, 50, lcd.rgb_to_565(255, 0, 0))
