I am currently working on expanding functionalities of the original Pico ePaper library. I want to add support to as much display options as possible
This module is a basic Micropython driver for GoodDisplay e-paper Displays often used by Waveshare, WeAct Studio, and others. It supports grayscale mode, partial updates and allows setting screen rotation. My goal doing this was to support as much options given by the driver chips as possible to the user. Along with the driver, this module also provides a simple drawing API that can be used to draw basic shapes and text on the screen that makes use of the on display ram, and micrypython's viper mode. This allows for faster drawing times, and drawing the display asynchronously. In addition, you may still use the FrameBuffer class to draw on the display.
Here are the currently supported displays:
- 1.54" 200x200 with SSD1681 driver GDEY0154D67
- 2.9" 296x128 with SSD1680 driver GDEY029T94
- 3.7" 480x280 with SSD1677 driver ED037TC1
- 4.2" 400x300 with SSD1683 driver GDEW042T81 / GY-E042A87 (no fast mode)
*If your display is not listed, you can try to use the driver for the closest resolution and driver. It may work, but it may not. Using the other epd files as a reference, you can try to make your own driver.
Also, I have only tested this module on ESP-32s, and RP2040, the library may not work as expected on other ports.
I'm in the process of creating the examples.
You can find all the documentations about how this library works here
If you want to make your own driver for you display, and the display's driver IC is in the SSD family, see the epd_maker documentation
- Copy the uEPD folder to your device's root directory. Import your the class corresponding to your EPD from it.
