Real Time Operating Systems with Brian Amos

Listen Later

Welcome, Brian Amos, author of Hands-on RTOS with Microcontrollers

  • Learned about the book from past guest Phillip Johnston. Also talked to Alvaro Prieto (Unnamed RE) about FreeRTOS.
  • "How do I RTOS?"
  • When do you want to use a Real Time Operating System (RTOS)?
    • Assume you can from a state machine
    • User interface you'll want it
    • Communication capability (IoT devices)
    • Differentiating OS vs RTOS
    • Amazon acquired FreeRTOS in 2017
    • FreeRTOS is a bottom up methodology
    • It's possible to make a completely statically allocated memory for a project (no heap, no malloc, etc)
    • Simple examples around reading a sensor, pump status, screen, internet
    • System level design decisions
    • Interrupt Service Routine (ISR)
    • Ticks are important
    • How did Brian get into this?
    • Brian was working on a product that had a
      • Telos module
      • MSP430
      • TinyOS
      • nesC?
      • James Grenning's book on TDD for embedded
      • Modern micros can do a lot in parallel, especially using hardware like DMA
      • Troubleshooting an RTOS
        • SEGGER Ozone (debugger)
        • SystemView
        • Percipio Tracealyzer
        • Many of the graphics in the book are available on Brian's github page as CC by SA licensing
        • Page 48 graphic
          • Brian taunts us on Page 98 showing lots of STM32 parts in stock...
            • NucleoF7 board used in examples (unsurprisingly...out of stock)
            • There's an onboard debugger that you can reprogram to Segger
            • Going through exercises
            • Working with HALs
            • Logic analyzer for troubleshooting
            • Embedded Linux
            • Still goes bck to superloop
