GND	GND
SCL	SCL
SDA	SDA

Write Script

import time
from pinpong.board import Board
from pinpong.libs.dfrobot_ssd1306 import SSD1306_I2C #Import ssd1306 library

Board("F1C").begin()

oled=SSD1306_I2C(width=128, height=64, bus_num=0) #Initializes the screen, transmits in the numbers of screen pixels

while True:
  oled.fill(1) #fully filled display
  oled.show() #Display is valid
  print("1")
  time.sleep(1)

  oled.fill(0) #turn off fully filled, clear the screen
  oled.show() #Display is valid
  print("0")
  time.sleep(1)

  oled.text(0) #Display numbers
  oled.text("Hello PinPong",8,8) #Display texts at specified location
  oled.show()  #Display is valid
  time.sleep(2)

Check the result

Use the following command to verify if it succeeded.
