fargin' firmware ...

• is a framework for programming microcontrollers

• consists of

  • low-level native mcu code and

  • high-level interpreted code

interpreted code (Lua) ...

• provides low-threshold / high ceiling programmability - it's easy to write simple applications, yet handles complex tasks as well

• can be modified remotely (for example, via satellite)

• can be modified on-the-fly - i.e. without restarting

• source is stored in flash file system

• the interpreter and compiler are part of native mcu code

native mcu code ...

• is minimal, well wrung out and highly testable

• has low error potential

• is written entirely in C

• may never need firmware upgrades

• consists of

  • RIOT OS ("The Friendly Operating System for the Internet of Things")

    • provides portability

    • makes native mcu coding easier than with other/no RTOS

  • Lua compiler and interpreter

  • Lua startup code

  • a uniform service request/response interface between the Lua interpreter and RIOT OS

  • a serial interface (uart, USB, bluetooth, etc) to a PC for

    • developing/testing the Lua code

    • testing the native mcu code

    • testing the hardware

development is ongoing: fargin-firmware
