Datasheet

This is a basic polling example - we'll check each GPIO.input in order, and draw a different shape - a directional arrow

or a round circle) depending on whether the button is pressed. If the button is pressed we have the shape filled in. If

the button is not pressed, we draw an outline only

Then we run disp.image(image) and disp.display() to actually push the updated image to the OLED. This is required

to actually make the changes appear!

A small time.sleep() delay just keeps the OLED from getting flickery and 'de-bounces' the button inputs.

More Demos & Examples

You can check out our other examples in the example, just make sure to edit each one with nano animate.py for

example, and find the line that says:

try:

while 1:

if GPIO.input(U_pin): # button is released

draw.polygon([(20, 20), (30, 2), (40, 20)], outline=255, fill=0) #Up

else: # button is pressed:

draw.polygon([(20, 20), (30, 2), (40, 20)], outline=255, fill=1) #Up filled

if GPIO.input(L_pin): # button is released

draw.polygon([(0, 30), (18, 21), (18, 41)], outline=255, fill=0) #left

else: # button is pressed:

draw.polygon([(0, 30), (18, 21), (18, 41)], outline=255, fill=1) #left filled

if GPIO.input(R_pin): # button is released

draw.polygon([(60, 30), (42, 21), (42, 41)], outline=255, fill=0) #right

else: # button is pressed:

if GPIO.input(D_pin): # button is released
