UART Protocols and Applications in Embedded Systems
网页2021年1月20日 · 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 …
USB Type-C and power delivery 101 – Ports and connections
网页2017年5月8日 · 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 …
MISRA C: Rules, Guidelines, and Compliance - Embedded
网页2002年7月1日 · MISRA C Rules and Guidelines. In all, MISRA C has 127 rules. Of these, 93 are required and the remaining 34 are advisory. The distinction between these two types of rules is important. C code that claims conformance to MISRA C must comply with all 93 required rules. Conforming code should adhere to the advisory rules as much as is …
Serial Communication Protocols Compared - Embedded
网页2002年5月31日 · 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.
Direct Memory Access (DMA) - Embedded
网页2003年10月14日 · 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 interrupts, increases data …
Ring Buffer Basics - Embedded
网页2013年8月7日 · 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
网页2002年10月29日 · 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 …
5 Steps To Designing An Embedded Software Architecture, Step 1
网页2022年9月16日 · There are five steps teams can use to develop and evolve their software architecture: Separate the software architecture. Identify and trace data assets. Decompose the system. Interface and component design. Simulate, iterate, and scale.
USB Type-C and power delivery 101 – Power delivery protocol
网页2017年5月15日 · 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 …
