UART Protocols and Applications in Embedded Systems
WEBJan 20, 2021 · UART in embedded system. Embedded systems, microcontrollers, and computers mostly use a UART as a form of device-to-device hardware communication protocol. Among the available communication protocols, a UART uses only two wires for its transmitting and receiving ends. Despite being a widely used method of hardware communication protocol, it is ...
USB Type-C and power delivery 101 – Ports and connections
WEBMay 8, 2017 · 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. From a form factor perspective, the USB Type-C connector combines multiple USB connectors – Micro-B, Type-A ...
Direct Memory Access (DMA) - Embedded
WEBOct 14, 2003 · Direct memory access (DMA) is a means of having a peripheral device control a processor’s memory bus directly. DMA permits the peripheral, such as a UART, to transfer data directly to or from memory without having each byte (or word) handled by the processor. Thus DMA enables more efficient use of …
Serial Communication Protocols Compared - Embedded
WEBMay 31, 2002 · RS-422 and RS-485 protocols. TIA/EIA-422-B (typically referred to as RS-422) and TIA/EIA-485-A (typically referred to as RS-485) are balanced, twisted-pair interfaces capable of speeds up to 10Mbps and distances up to 4,000 feet. Being differential buses, each uses signals from 1.5V to 6V to transmit the data.
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.
Designing a Vehicle Instrument Panel Cluster—A Case Study
WEBOct 29, 2002 · Communication protocols such as SAE J1850, CAN, and KW2000 are commonly used for automobile inter-module communication. The Instrument Panel Cluster (IPC), or Vehicle Dashboard, is one of the few devices with which the vehicle communicates to the driver. Devices such as a driver information center and heads-up display are considered subsystems ...
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 ...
Introduction to Counter/Timers - Embedded
WEBAug 28, 2002 · Here's a primer on the hardware. Counter/timer hardware is a crucial component of most embedded systems. In some cases, a timer measures elapsed time (counting processor clock ticks). In others, we want to count or time external events. The names counter and timer can be used interchangeably when talking about the hardware.
USB Type-C and power delivery 101 – Power delivery protocol
WEBMay 15, 2017 · 1. 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 …
