Overview

Ted starting a wiki page to hold notes and findings from working through demos and tutorials on FreeRTOS operating system. First goals include:

• Learning what target CPUs, dev boards and systems run FreeRTOS
• Learning what emulators run and support testing of FreeRTOS instances

^ First Topics Explored

RTOS fundamentals covered in pages of FreeRTOS site:

• https://www.freertos.org/implementation/a00002.html

These initial links will likely be moved or removed, they're just first places Ted checked out at FreeRTOS site:
