Power factor measurement using PIC18f4520 – I have a 10” square fan, with 0.06/0.08Amps, 220/240V, 50Hz, properly working. I want to digitally measure the power factor of the fan, under all possible circumstances (voltage fluctuations, source dampings, etc.). I’ve read about Zero Crossing Detection Method, that enters the analogue quantities of voltage/current consumed by the inductive load […]

CES 2016: the largest collection of insecure devices in the world
By Alan Grau The annual Consumer Electronics Show in Las Vegas has just wrapped up. With 160,000 attendees, 3,800 exhibitors and almost 2.5 million square feet of exhibit space, this is the largest electronics show in the world. The array of new products and technologies has been featured on virtually every media outlet from Good […]
Using input devices on embedded Linux demo: USB mouse on Intel Edison
By Tahmid I have recently been using the Intel Edison for the Cornell robotics project team (which co-hosts the Intel-Cornell Cup USA competition). Building on my previous knowledge of embedded systems, I started learning to use and program on Linux. The distro used is Yocto (all information is available on the Intel Edison website). One […]
Reduce preemption overhead in real-time embedded systems
by John A. Carbone Real-time embedded systems are expected to perform with predictable, real-time responsiveness. But in some cases, the functionality that enables that responsiveness can actually bloat the system and challenge its ability to perform as needed. With preemption-threshold scheduling, developers can reduce preemption overhead, while still enabling applications to meet real-time deadlines. The […]

Serial communication interrupt flag in PIC18f4520 and mikroC Pro for PIC – I wrote a code to send and receive data serially in an application that will update a 16-segment display. If a string of characters is received, an interrupt will occur for every character received in the string. I thought of taking a variable and increment it […]
What do embedded developers need to know about IoT security?
by Alan Grau Cyber-attacks against IoT devices continue to make headlines, with the Fiat Chrysler Jeep hack just the most recent. By now, most embedded developers understand the need for security, but news reports show that understanding the need is not enough. At a recent trade show I spoke with a number of vendors providing […]
A beginner’s guide to microcontrollers
by Jon Wilder Time after time I see beginners try to get started in embedded electronics, only to be overwhelmed and not know where to start. Some even make the mistake of trying to write their own code without first gaining a thorough understanding of the microcontroller/microprocessor they’re working with, the programming language they’re working […]
