The operation and description of the UART serial interface through USB is discussed in this application note. In addition, the firmware application code in C language, containing communication ...

The UART, or universal asynchronous receiver-transmitter, is one of the most used device-to-device communication protocols. This article shows how to use a UART as a hardware communication protocol by ...

The simulation of a serial port in software in order to allow USB, Ethernet or some other input/output port to take its place. Virtual serial ports are necessary to enable an application that was ...

This application note describes how to configure Zilog’s Z8051 Universal Serial Interface (USI) peripheral to operate as a Universal Asynchronous Receiver Transmitter (UART). C code drivers for both ...

I had a thread over in the Programmer's Symposium, but I think the line of questioning has turned more into a kernel issue.<br><br>I have been tasked with getting response time for writing a single ...

This simple WiFi serial port monitor would have saved us a lot of trouble. We can’t count how many times where being hooked into an Arduino with USB just to get the serial out has nearly been more ...

In the last two installments of Driving Me Nuts [LJ August 2002 and October 2002], we covered the tty layer, explaining how to create a minimal tty driver. We also explained some of the various ioctls ...

A bootloader makes it possible to update a product’s firmware in the field. Common communication interfaces like UART, I 2 C, SPI or USB can be used to update the firmware, which typically involves a ...

Your friend is mistaken. This serial port he is talking about is called "CGA" and closely resembles a serial port. However it still requires a graphics card and a monitor! You can convert a CGA signal ...

[Jacob Geigle] had a problem. A GPS unit and a Bluetooth-to-serial were tying up all the hardware UARTs on an AVR Arduino project. “Software serial”, I hear you say. But what if I told you [Jacob] ...

Although serial port connections have been replaced by USB ports in most computers, older business equipment such as fax machines and printers may still utilize them. When a serial port stops ...
