David Montero Crespo bcc7129aa3 feat: Add support for SSD168x ePaper panels 
- Introduced EPaperPanels.ts to define configurations for various ePaper panels including dimensions, refresh rates, and controller details.
- Implemented SSD168xDecoder.ts to handle the decoding of SPI commands for the SSD168x family of ePaper displays.
- Created EPaperPart.ts to manage the simulation of ePaper panels, integrating with the existing simulator architecture and handling events.
- Added example sketches for 2.13", 2.9", 4.2", and 7.5" ePaper displays, demonstrating basic functionality and text rendering.
- Ensured compatibility with AVR, RP2040, and ESP32 platforms, with appropriate pin configurations for each.

test_epaper — ePaper / e-Ink display emulation

Workspace for adding ePaper (electrophoretic) display support to Velxio. Built off the ILI9341 / SSD1306 patterns already living in frontend/src/simulation/parts/ComplexParts.ts and frontend/src/simulation/parts/ProtocolParts.ts.

Status

  • Research phase: read autosearch/ to see what's been investigated.
  • Tests phase: pytest tests verify SPI protocol decoding without QEMU; sketch tests verify cross-board compilation; E2E pixel-buffer tests come last (blocked on emulator scaffold).

How to run (when tests exist)

# Pure Python protocol decoder tests (no backend, no QEMU)
pytest test/test_epaper/ -v

# Cross-board sketch compile (requires backend on :8765)
VELXIO_BACKEND_URL=http://127.0.0.1:8765 pytest test/test_epaper/test_compile_*.py -v
