For OLED's using the SSD1306 driver:
• First load the driver:
  with the RP2040 plugged in, open Thonny
  Tools > Manage Packages
  type SSD1306 in the search bar, press enter
  click to select micropython-ssd1306
  click Install
• import into python program:
  from ssd1306 import SSD1306_I2C
• Initially I'll use the I2C1 port
  SDA - pin 2
  SCL - pin 3
