	Description:		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 Find Brian on: LinkedIn GitHub Amazon book
