Flare 🔥

Under development - doesn't really do anything yet

Wireless lighting platform for various hardware and creative applications.

Designed around Nordic's nRF52 SoC (ARM Cortex M4, Bluetooth 5, 512kB Flash, 64kB RAM), but will also work on the nRF51 series or other Zephyr supported boards (depending on which Flare features are enabled).

Roadmap

• Configurable for multiple hardware platforms
• LED Drivers
  • PWM
  • TI I²C driver IC
  • WS2812, APA102 (maybe)
  • Dummy (development)
• Control via Bluetooth Low Energy GATT
• iOS ANCS support
• Bluetooth Mesh
• Effects generator
• Pre-generated effect support
• Start-up memory mode
• iOS/Android app
• BLE beacon / presence awareness
• Battery management system
• Sensor support (light, temperature, motion)
• Raspberry Pi / IP gateway
• DMX interface
• Docker build environment

Development setup

1. You need Zephyr 1.11.0 installed.
2. You also need the GNU Arm Embedded Toolchain (we're using 7-2017-q4-major, but any recent should work).
3. Make sure these environment variables set:
   • ZEPHYR_BASE: the path to Zephyr e.g. ~/zephyr.
   • ZEPHYR_TOOLCHAIN_VARIANT: gccarmemb.
   • GCCARMEMB_TOOLCHAIN_PATH: the path to gcc-arm e.g. /usr/local/gcc-arm/gcc-arm-none-eabi-7-2017-q4-major.
   • In fish shell, you can persist these using: set -Ux ZEPHYR_BASE ~/zephyr.
