Code example

We use here the libraries adafruit-blinka and adafruit-circuitpython-charlcd which were published by adafruit. They are released under the MIT license. But before you can use them you first have to execute the following commands in the console on your Raspberry Pi

After you have done this you can now install adafruit-blinka and adafruit- circuitpython-charlcd on your Raspberry Pi by running the following commands JOY-IT 20x4 LCD Module with 16 Pin Header 4

Now, after you have installed the two libraries, you can create a new file using the following command

and there, you can simply copy in the following code JOY-IT 20x4 LCD Module
with 16 Pin Header 6
