fargin firmware ...

• is a framework for programming microcontrollers

• consists of

  • low-level native mcu code and

  • high-level interpreted code

interpreted code (Lua) ...

• provides for low-threshold / high-ceiling application programming

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

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

• source code 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

• firmware upgrades not usually needed after deployment

• 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 native mcu code

    • between a PC and the native mcu code via USB, UART, etc for

      • developing/testing the Lua code

      • testing the native mcu code

      • testing the hardware (the problem isn't always the software!)

Where to start? Try blinking an LED, obviously!
