A custom Featherwing to connect the e-Paper module to the HUZZAH 32
The IoT Calendar service to parse iCalendar feeds for IoT devices (iotcalendar.org)
Custom code for displaying the calendar, events, temperature and moon phase.
I have tested this with both the Adafruit HUZZAH 8266 and Adafruit HUZZAH 32. The HUZZAH 32 version actually works much better for larger e-Paper displays like the 4.2 inch display used here due to the increased memory usage needed to hold the display buffer. This could work on the HUZZAH 8266 if using a smaller e-Paper display. Waveshare makes e-Paper devices in several different sizes.
I made a custom Featherwing to make it easier to connect the Waveshare module to the HUZZAH device. In addition to making it easy to connect the 8 wires from the display, the custom Featherwing also includes a reset button and two additional buttons for software use. I use the additional buttons to put the device into a web based setup mode. I will be releasing this custom Featherwing on Tindie for those interested in it. Although Waveshare provides a graphics library for drawing on the e-paper display, I instead used the Adafruit GFX library, which was very easy to use with the display.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
