Architecture

MPU (Microprocessor) - Linux Side

  • Location: src/mpu/
  • Processor: Qualcomm Dragonwing QRB2210 (ARM Cortex-A53)
  • OS: Debian Linux
  • Language: Python 3
  • Communication: Bridge library, SSH, named pipes

MCU (Microcontroller) - Arduino Side

  • Location: src/mcu/
  • Processor: STM32U585 (ARM Cortex-M33)
  • OS: Arduino Core on Zephyr
  • Language: C++ (Arduino)
  • Communication: Bridge library, GPIO, peripherals

Development Workflow

  1. Edit code in respective directories:

    • MPU code: src/mpu/main.py
    • MCU code: src/mcu/main.ino

  2. Build MCU sketch:

    npm run build

  3. Deploy both:

    npm run deploy

  4. Monitor:

    npm run logs

Communication

  • MPU → MCU: Bridge library commands
  • MCU → MPU: Bridge library responses
  • File transfer: SSH (SCP)
  • Real-time data: Named pipes (/tmp/unoq_cmd.pipe)
  • Status updates: JSON files (/tmp/unoq_status.json)
