# 128x64 display with hardware I2C:

disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST)

variant for creating the display object! The rest can remain commented out.

Note that above, we initialize RST = None because the OLED Bonnet does not require a reset pin.

Display Initialization

The next bit of code will initialize the display library with begin() and clear the display with clear() and display() .

Then it will configure a PIL drawing class to prepare for drawing graphics. Notice that the image buffer is created in 1-

bit mode with the '1' parameter, this is important because the display only supports black and white colors.

We then re-draw a large black rectangle to clear the screen. In theory we don't have to clear the screen again, but its a

good example of how to draw a shape!

Button Input & Drawing

Once the display is initialized and a drawing object is prepared, you can draw shapes, text and graphics using PIL's

drawing commands (https://adafru.it/dfH).

# Initialize library.

disp.begin()

# Clear display.

disp.clear()

disp.display()

# Create blank image for drawing.

# Make sure to create image with mode '1' for 1-bit color.

width = disp.width

height = disp.height

image = Image.new('1', (width, height))

# Get drawing object to draw on image.

draw = ImageDraw.Draw(image)

# Draw a black filled box to clear the image.

draw.rectangle((0,0,width,height), outline=0, fill=0)
