So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

I have a PC-based DSO that connects via parallel port that I'd like to get working via USB (preferable) or at least ExpressCard. I picked up a USB-parallel adapter from MicroCenter thinking it would ...

This application note presents the process of converting a serial output into parallel output using common serial-to-parallel register integrated circuits. The document also discussed the CS556x/7x/8x ...

For PCI bus interfacing, the OX16PC1952 brings together a PCI interface, two high performance serial channels, and a parallel port in one compact, 128-pin TQFP package. This integrated bridge device ...

In most sigma-delta analog-to-digital converter (ADC) applications, the serial data transfer occurs through a serial port. A microcontroller configures the serial port as required—setting the baud ...

This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port. It converts a serial 2400 baud signal into a parallel signal.

A socket that connects to a serial interface (one bit following another over one line). Serial ports are widely used by sensors for data acquisition, and they were standard on early computers for ...
