To do so, the Arduino was set up to monitor the BUSY line on the printer’s parallel port, setting the CTS line active whenever the busy line was inactive.

Details of interface construction and the mapping of Arduino pins to GPIB control signals and data bus are explained in the "Building an AR488 GPIB Interface" section of the AR488 Manual. Commands ...

RS232 Interface Circuit Descreption MAX232 from Maxim Corp. is a line driver IC for RS232 Interface, MAX232_TX and MAX232_RX is connected to Rx and TX pins of UART1 on ATMEGA256. T1Out and R1In is ...

[Dimitri Diakopoulos] dropped into our tip line to let us know his HIDUINO project. The HIDUINO is a set of firmware for the ATmega8u2 used in the new revisions of the Arduino (Uno, and Mega2560 f… ...

Requisite hardware setup is very simple: just verify and upload the below sketch to Arduino Uno and that’s all! The sketch enables Arduino to receive instructions (which will actually be in ASCII) ...

A clever way to consolidate enough power from the TX data and handshake lines on an RS-232C port to run a small circuit. The typical RS232 transceiver interface IC found in many embedded systems ...

Arduino boards have digital and analog pins that can be used as inputs or outputs. You can also use serial, SPI, I2C, or other communication protocols to interface with more complex devices.

This paper presents an optical transceiver, whose packet process is completed with deficit round robin (DRR) and RS232 interface, for optical synchronous optical networking (SONET) which can service ...
