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 ...
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 ...
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.
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.
MISRA C: Rules, Guidelines, and Compliance - Embedded
WEBJul 1, 2002 · 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 …
Flash 101: NAND Flash vs NOR Flash - Embedded
WEBJul 23, 2018 · The downside of smaller blocks, however, is an increase in die area and memory cost. Because of its lower cost per bit, NAND Flash can more cost-effectively support smaller erase blocks compared to NOR Flash. The typical block size available today ranges from 8KB to 32KB for NAND Flash and 64KB to 256KB for NOR Flash.
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 …
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 …
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 ...
