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 […]

Top microcontroller threads on EDAboard.com – December
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 […]
