There is a lot of misinformation about multithreaded programming and the use of real-time operating system features. Misinformation and programmer inexperience often leads to poor task decomposition and introduces system failures such as task starvation, deadlock, and priority inversion. This course teaches the proper use of C and RTOS APIs to develop multithreaded software. Variants of the course cover specific RTOS APIs and features, such as VxWorks and µC/OS-II.

Length/Options

• 2 days (hands-on with µC/OS-II)
• 1 day (lecture only, choice of RTOS)

Audience

• Firmware developers evaluating or using a real-time operating system

Prerequisites

• Familiarity with the C programming language
