The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.
debugWIRE is supported by all modern hardware debuggers from Microchip.This includes Atmel-ICE, [3] JTAGICE3, AVR Dragon, JTAGICE mkII, and SNAP. [4] It is also possible to build a cheap debugWIRE hardware debugger [5] based on an open-source Arduino sketch, [6] using a general USB-Serial adaptor or ATtiny85 board, [7] or a CH552 microcontroller.
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.
It is sometimes called a four-wire serial bus to contrast with three-wire variants which are half duplex, and with the two-wire I²C and 1-Wire serial buses. Typical applications include interfacing microcontrollers with peripheral chips for Secure Digital cards, liquid crystal displays , analog-to-digital and digital-to-analog converters ...
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.
RS-232 / Current loop converter. For serial communications, a current loop is a communication interface that uses current instead of voltage for signaling. Current loops can be used over moderately long distances (tens of kilometres), and can be interfaced with optically isolated links.
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]
For example, two GPIOs may be used to implement a serial communication bus such as Inter-Integrated Circuit , and four GPIOs can be used to implement a Serial Peripheral Interface (SPI) bus; these are usually used to facilitate serial communication with ICs and other devices which have compatible serial interfaces, such as sensors (e.g ...
