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 […]

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 […]
