#21 Foreground-Background Architecture (“Superloop”)

Introduction to the ubiquitous foreground-background architecture, also known as the “superloop” or main+interrupts. Apart from being interesting in its own right, foreground/background is the starting point for all embedded software architectures and, among others, is an important stepping stone to understanding a Real-Time Operating System (RTOS), which was perhaps the most requested subject for me to explain. So, you can view this lesson as a prerequisite for the upcoming lessons about the RTOS as well as other architectures.
