Supporting both IEEE1284-I and -II bi-directional parallel communications between personal computers and peripherals, the 74LVC161284TTR and 74LVCZ161284ATTR parallel-port transceivers can each ...
A simple, inexpensive method for building a temperature strip-chart recorder involves a parallel port that communicates with four TMP121 IC temperature sensors (Fig. 1). The sensors communicate via ...
High-resolution temperature sensing at low cost is possible using only one chip attached to the PC's parallel port (Figure 1). The Dallas Semiconductor (www.dalsemi.com) DS1722 digital thermometer ...
The 24-bit I/O card project has been designed to function with parallel/printer port of an Amiga or computer using the Intel 82C55 I/O chip. The design of the device contains read & write strobe, a ...
With the continuing manufacture of new computers, there is a clear and obvious trend of the parallel port becoming less and less common. For our younger readers; the parallel port is an interface ...
Most modern equipment is connected over USB, and generally speaking we’re all the better for it. But that’s not to say there aren’t some advantages to using serial and parallel ports. For example, the ...
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 ...
