Datasheet

First a few modules are imported, including the Adafruit_SSD1306 module which contains the OLED display driver

classes. You can also see some of the Python Imaging Library modules like Image, ImageDraw, and ImageFont being

imported. Those are, as you can imagine, are for drawing images, shapes and text/fonts!

Pin Setup

Next up we define the pins that are used for the joystick and buttons. The Joystick has Left, Right, Center (press in), Up

and Down. There's also the A and B buttons on the right. Each one should be set as an input with pull-up resistor.

Display Setup

Below the configuration values is the display class setup. There are 4 variants of OLED displays, with 128x32 pixels or

128x64 pixels, and with I2C or with SPI.

However since the OLED Bonnet is a 128x64 I2C display

only

you should only use the

import RPi.GPIO as GPIO

import time

import Adafruit_GPIO.SPI as SPI

GPIO.setmode(GPIO.BCM)

GPIO.setup(A_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP) # Input with pull-up
