Way back in the day, analog/digital converters (ADCs) had simple, parallel interfaces, either TTL or high-level CMOS. Many of these converters could be clocked down to zero samples/second: once you ...

After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s. This extends ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Practically every electronic product made today uses one or more serial data interfaces. A serial interface is the ...
