Created with love in Canada, visit hostnodejs.com today MicroPython drivers for various Waveshare e-Paper displays, based on the original Waveshare Raspberry Pi examples found in the wiki. I recently got a Waveshare E-Paper Display, in order to learn more about displays – programming and using them with microcontrollers. I chose specifically the e-paper because of its features like very low power consumption (up to 8mA only when refreshing) and preserving the state when unpowered. The latter can be especially handy for battery-powered sensor devices.

Think of an environmental sensor that measures data only once in a while and sleeps in between, but with e-paper, it can display e.g. the last measurement all the time without affecting battery life. For starters, I got the pretty small, 1.54" display, with three available colours, i.e. black, red, and no colour. The Waveshare E-Paper Display (EPD) communicates via SPI, uses 6 pins for communication (which with power supply makes 8 in total). It comes with libraries for Arduino, Raspberry Pi (in Python and C++) and STM32, so you're all set on these platforms.

For other environments, well, tough luck. The Python library for Raspberry Pi uses PIL (Python Imaging Library) for displaying text and images. It's awesome because it greatly simplifies the implementation. PIL is however not available in MicroPython, so I had to resort to drawing text using fonts defined in the code as arrays. Here's the example definition of a letter 'A' in a 24-pixel font: Full font definition is available here.

3x24 = 72 bytes are required for a single character. Now multiply it by the number of printable ASCII characters (95, in the 32-127 range) and you'll get 6840 items in the list. Even for the small 8-pixel font the list has 760 elements. An open API service indexing awesome lists of open source software.

Micropython package to control HD44780 LCD displays 1602 and 2004 via I2C Fast MicroPython driver for GC9A01 display modules written in C E‐paper (a.k.a. “E‐Ink”) displays are perfect for low‐power and daylight‐readable applications. In this post, we’ll show how to wire up an 800 × 480 e‐paper display to a Raspberry Pi Pico, then walk through the MicroPython code to display images. We need to use the SPI interface of the Pico.

The Pico 2 has two SPI interfaces: SPI0 and SPI1. We’ll use SPI0. See the pinout below. Below are my pin connections. The e‐paper typically has the following signals: For DC, RST, BUSY, you can actually use any GPIOs you want.

I just randomly picked GP8, GP9, GP10. Of course, if you want to use other GPIOs, you need to change the code accordingly. Save the following script (e.g. epaper_800x480.py) to your Raspberry Pi Pico via Thonny or any other method. It defines a driver class, initializes the display, and can show an image.
