In this simple, inexpensive design, the ADC, an AD7703, connects to the PC via its parallel port (Fig. 1).

For our younger readers; the parallel port is an interface standard used for bi-directional communication between a computer and a variety of peripherals. The parallel port’s demise is partially ...

There are four basic ways to connect a printer to a computer. It’s important to understand these before purchasing a printer or a new computer. Most old printers connect using a parallel port on ...

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 ...

USB-to-Parallel Adapters You can use a USB-to-parallel adapter cable to connect most parallel printers to computers that have USB ports but not a Centronics-type 36-pin adapter port.

Therefore, this circuit can send data to an SPI, I 2 C , or SMBus serial interface, or to an 8-bit parallel-out serial shift register such as the SN74HC164, which can operate at 2 V.

advertisement 05-29-2019 TECH An oral history of USB, the port that changed everything Ajay Bhatt was just struggling to upgrade his computer. An oral history of the one interface to rule them all.

The A port pins of the interface have standard 4mA totem-pole outputs. The B port pins offer the ability to source or sink up to 14mA. All the inputs offer a degree of hysteresis to improve their ...
