View a picture
Draw text
Draw shapes
Whatever you draw is stored in the instance variable
image. You can show it on the oled screen with theshowmethod.In this class, drawing text or pictures is defined as changing the data of the instance variable
image.example:
from openpibo.oled import OledbyST7735 as Oled oled = Oled() # 아래의 모든 예제 이전에 위 코드를 먼저 사용합니다.
- show()[source]¶
Shows the instance variable
imageon the oled screen.If you do not use this method, nothing is shown on the oled screen even if you draw.
example:
# 그림을 그린 후 oled.show()
- clear(image=True, fill=True, show=True)[source]¶
Resets the instance variable
imageand clears the oled screen.example:
oled.clear()
