SSD1680 Tri-Color E-Paper

The SSD1680 Tri-Color E-Paper is an SPI device in the LabWired part catalog. Its catalog type is ssd1680_tricolor_290. It connects to the MCU over SPI. The catalog gives a supply range of 2.2–3.7 V. It has 8 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How it was validated

Checked against a capture. Compared against a recorded trace or capture from real hardware, with the record kept in the repository.

Wire capture of the GxEPD2_290_C90c init stream (12 01 27 01 00 11 03 3c 05 18 80 21 00 80 44 …) off a WeAct 2.9" B/W/R module, checked against WeAct's reference driver; the model implements exactly those 15 commands. Panel RESPONSES were never compared against real glass, so this is capture, not hardware.

How to simulate the SSD1680 Tri-Color E-Paper in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the SSD1680 Tri-Color E-Paper (catalog type ssd1680_tricolor_290).
  3. Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 2.2–3.7 V.
  4. Connect CLK and DIN to the SPI pins of the board.
  5. Connect CS to the chip-select pin of the board, or to a free GPIO.
  6. Connect DC, RST and BUSY to free GPIO pins.
  7. Run the firmware. It selects the part and moves bytes over the simulated SPI bus as on hardware.
