A practical guide to microcontroller structure and performance factors
Microcontroller units (MCUs) are single-chip computers optimized for performing embedded computing tasks like controlling a coffee machine or a medical device, an industrial robot, or an electric vehicle battery charger. They don’t require a complex operating system (OS) like those found on personal computers and servers. The central processing unit (CPU) is a key element […]
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 […]
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 […]
IoT from the ground up: MCUs and connectivity building blocks
In the emerging world of the Internet of Things (IoT), the tiny MCU is becoming the mighty MCU. But why and how does a device that has been around for decades figure into the ultra-low-power, connected, and still-unrealized world of the Internet of Things? And why is IoT connectivity any different from the connectivity we […]
