The physical hardware communications link (physical layer) is not defined by SCPI. [5] While it was originally created for the IEEE-488.1 (GPIB) bus, [5] SCPI can also be used with RS-232, RS-422, RS-485, USB, Ethernet, VXIbus, HiSLIP, etc. [5] SCPI commands are ASCII textual strings, [5] which are sent to the instrument over the physical layer ...
Automatic baud rate detection (ABR, autobaud) refers to the process by which a receiving device (such as a modem) determines the speed, code level, start bit, and stop bits of incoming data by examining the first character, usually a preselected sign-on character on a UART connection. ABR allows the receiving device to accept data from a ...
Each GPIO port on a tiny or mega AVR drives up to eight pins and is controlled by three 8-bit registers: DDRx, PORTx and PINx, where x is the port identifier. DDRx: Data Direction Register, configures the pins as either inputs or outputs. PORTx: Output port register. Sets the output value on pins configured as outputs.
The Arduino Nano is an open-source breadboard-friendly microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2008. It offers the same connectivity and specs of the Arduino Uno board in a smaller form factor.
In computing, the Java Debug Wire Protocol (JDWP) is a communication protocol which is part of the Java Platform Debugger Architecture. [1] It is used for communication between a debugger and the Java Virtual Machine, which it debugs. It allows to debug processes on a different computer. It can work over a network socket or through shared memory.
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [ 1 ] [ 2 ] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
