To use the Sharp Memory Display with your Adafruit CircuitPython board you'll need to install the Adafruit CircuitPython SharpMemoryDisplay module on your board.
First make sure you are running the latest version of Adafruit CircuitPython for your board.
Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these libraries from Adafruit's CircuitPython library bundle. Our CircuitPython starter guide has a great page on how to install the library bundle.
If you choose, you can manually install the libraries individually on your board:
Before continuing make sure your board's lib folder or root filesystem has the adafruit_sharpmemorydisplay.mpy and adafruit_framebuf.mpy files copied over.
Next connect to the board's serial REPL so you are at the CircuitPython >>> prompt.
