A Beginner's Guide to Embedded Systems

Manasi Rajan

I was in my Junior year of college when I first learned about embedded systems. Sure, I’d heard about this mystical world of sensors and IoT, the same way I’d heard about thermonuclear astrophysics; But, the phrase “embedded systems”...


Peripheral Interaction Without a Linux Device Driver Using Spidev

Mohammed Billoo

Overview When integrating a new peripheral onto an embedded Linux platform, we might think we always need to implement a kernel module to serve as a device driver. However, as we all know, absolutes such as “always” and “never” are...


In Memoriam: Frederick P. Brooks, Jr. and The Mythical Man-Month
