UART Protocols and Applications in Embedded Systems
WEBJan 20, 2021 · The UART, or universal asynchronous receiver-transmitter, is one of the most used device-to-device communication protocols. This article shows how to use a UART as a hardware communication protocol by following the standard procedure. When properly configured, the UART can work with many different types of …
Introduction to Watchdog Timers - Embedded
WEBOct 1, 2001 · Generally speaking, a watchdog timer is based on a counter that counts down from some initial value to zero. The embedded software selects the counter’s initial value and periodically restarts it. If the counter ever reaches zero before the software restarts it, the software is presumed to be malfunctioning and the processor’s reset signal ...
Ring Buffer Basics - Embedded
WEBAug 7, 2013 · The ring buffer (also known as a circular buffer, circular queue, or cyclic buffer) is a circular software queue. This queue has a first-in-first-out (FIFO) data characteristic. These buffers are quite common and are found in many embedded systems. Usually, most developers write these constructs from scratch on an as-needed basis.
Task Scheduling in Embedded System
WEBNov 18, 2016 · Schedulers in Embedded Systems/RTOS. As we know, the illusion that all the tasks are running concurrently is achieved by allowing each to have a share of the processor time. This is the core functionality of a kernel. The way that time is allocated between tasks is termed “scheduling”. The scheduler is the software that determines which ...
USB Type-C and power delivery 101 – Power delivery protocol
WEBMay 15, 2017 · As described in the first part of this two-part series, USB Type-C is the newly introduced and powerful interconnect standard for USB. When paired with the new Power Delivery (PD) specification, Type-C offers enhancements to the existing USB 3.1 interconnect that lower the cost and simplify the implementation of power delivery over USB. In this article, we describe the USB Type-C power ...
Safely controlling an EV traction inverter - Embedded
WEBMay 18, 2020 · Safety is the prime concern when designing electric vehicle (EV) inverters and their control systems. This article discusses the requirements and outlines an example solution. Traction inverters are a critical component in electric vehicles, not only for functionality but also for safety. The inverter has three-phase output drives for each hub ...
5 Steps To Designing An Embedded Software Architecture, Step 1
WEBJacob Beningo is an embedded software consultant who specializes in real-time, microcontroller-based systems. He actively promotes software best practices through numerous articles, blogs, and webinars on topics from software architecture design, embedded DevOps, and implementation techniques.
Underfill revisited: How a decades-old technique enables
WEBJan 27, 2011 · Reinforcement using underfill is becoming more popular because bonding reliability and package strength may decline as chip packaging shrinks and becomes more compact, and PCBs are made thinner and smaller. Until recently, underfill was generally not necessary for typical device geometries and larger PCB assemblies.
I2C Protocol In Embedded Systems: An Introduction
WEBJul 31, 2001 · It is a simple, low-bandwidth, short-distance protocol. Most available I 2 C devices operate at speeds up to 400Kbps, with some venturing up into the low megahertz range. I 2 C is easy to use to link multiple devices together since it has a built-in addressing scheme. Philips originally developed I 2 C for communication between devices inside ...
The role of artificial intelligence in autonomous vehicles
WEBJul 15, 2020 · AI is used for several important tasks in a self driving automobile. One of the main tasks is path planning. That is the navigation system of the vehicle (Sagar and Nanjundeswaraswamy, 2019). Another big task for AI is the interaction with the sensory system and the interpretation of the data coming out of sensors.
