Overview

Key Features

• Native execution of the Lua scripting language, including
  • REPL
  • Non-volatile program storage
  • Rich, full featured API
    • Constants
    • Functions
    • Interrupts
• Build-time configurable, including:
  • Number of supported processor cores (maximum of eight)
  • Stack / Heap size, per core
  • Support for a configurable number and type of digital I/O protocols (GPIO, PWM, SPI etc)
  • Support for an FPGA fabric bus
  • Support for inter-core communication
  • Support for inter-core synchronization
  • Support for timers, hardware watchdogs and interrupts
• Run-time configurable, including:
  • Digital I/O Pin type (i.e. GPIO, UART, SPI etc)
  • API
