A helper library for displaying lines of text on a display using displayio.

Dependencies

This driver depends on:

  • Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_
  • Adafruit CircuitPython DisplayText <https://github.com/adafruit/Adafruit_CircuitPython_Display_Text>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://circuitpython.org/libraries>_ or individual libraries can be installed using circup <https://github.com/adafruit/circup>_.

This library works with any microcontroller with a built in display, or a microcontroller with an external display connected.

Purchase one from the Adafruit shop. <http://www.adafruit.com>_

Usage Example

This example takes the microcontroller CPU temperature in C and F, and displays it on the display under the heading "Temperature Data!".

.. code-block:: python

import microcontroller
from adafruit_simple_text_display import SimpleTextDisplay

temperature_data = SimpleTextDisplay(title="Temperature Data!", title_scale=2)

while True:
    temperature_data[0].text = "Temperature: {:.2f} degrees C".format(
        microcontroller.cpu.temperature
    )
    temperature_data[1].text = "Temperature: {:.2f} degrees F".format(
        (microcontroller.cpu.temperature * (9 / 5) + 32)
    )
    temperature_data.show()
