2024.02 Prototype (Airspeed - Venturi)

2024.01 Prototype (Airspeed - Pitot)

2023.12 Prototype (LCD Touch)

Introduction

The main goal for this milestone is to replace the e-paper with lcd screen, to experiment with faster refresh rates and multi-color rendering, compared to e-paper.

Try out the LVGL library. Also integration of GPS sensor with the UI data, first of all to get the geo and speed data, but also to try rendering the maps on screen.

Features

• [x] GPS
  • [x] Speed.
  • [x] Altitude.
  • [x] Heading.
  • [x] Maps.
    • [x] Tiles rendering.
    • [x] Tiles downloader.
    • [x] Tiles contverter to lvgl bitmaps.
    • [x] Rendering (very slow, requires lots of optimization)
• [x] Screen: WT32 sc01 plus
  • [x] Project setup.
  • [x] SDCard.
  • [x] LVGL
  • [x] Capacitive touch.
  • [x] Mock Data generator.

2023.10 Prototype (E-Paper)

Introduction

The most basic version of the device with only the live telemetry from Bluetooth LE sensors.

Features

• [x] integration with BLE sensors
  • [x] HR
  • [x] Power meter.
  • [x] Speed
