  7. What Is a Maker?

  8. Someone Who: • Has an idea for a new product or gadget • Learns by doing • Is a Hobbyist • Is an Inventor • Is a Hacker • Is in Startup Mode • In most cases: • Must minimize costs for tools, boards and embedded software • Is often a professional engineer (i.e. Maker Pro) working on an idea • Nights and Weekends

  9. Example Hobbyist / Maker Projects • Smart Garage Door Opener • Weather Station • 3D Printer • Drone • Home Automation • R/C Vehicles • Robots • Games • Teaching Aids • IoT Question 1 – Working on hobby / entrepreneur projects?

  10. Brief RTOS Introduction

  11. Operating System vs Kernel • An operating system is a collection of software components that provides useful services to your application code • A kernel is a subset of an operating system Application File System GUI TCP/IP Kernel USB RTOS Bluetooth RS-232 Hardware

  12. What is a Real-Time Kernel? • Software that manages the time of a CPU • Application is split into tasks • Each task has its own CPU registers • Each task has its own stack • Each task has its own priority • A task typically manipulates variables/arrays/etc. • A task can manage I/O devices Variables Arrays Structures (RAM) CPU Registers Task (Priority) Stack (RAM) I/O Devices (Optional)

  13. Tasks in a Kernel-Based Application Task Each Task Task High Priority Task Event Task Importance Task Task Infinite Loop Task Low Priority Task

  14. Most Kernels are Preemptive Via a kernel call, the ISR makes the high priority task ready Interrupt Occurs ISR completes and the kernel switches to the high-priority task ISR ISR The kernel switches to the low-priority task High-priority task Low-priority task Time

  15.
