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 recently learned a little bit of Visual Basic. I came up with an idea just a few minutes ago about a circuit that i could build that plugs into the parallel port that would control the speed of ...

[Pulko Mandy] doesn’t use his flash ROM programmer very often, but he does use it. When he tried to get support for a new chip and the manufacturer suggested he just buy a newer version he decided to ...

Many designers require that their PCs act as complete control systems without any internal hardware. For this function, users need at least one channel of analog data acquisition to monitor the ...

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 ...

The oscilloscope utilizes the SPP or EPP parallel port LPT1 for reading the data from ADC0820 (TLC0820). The program will automatically switch the LPT1 in byte mode or normal mode if the LPT is an ECP ...

If you want to talk to a typewriter using something other than your fingers on the keys, you could do a lot worse than to pick up a specimen featuring a Centronics parallel port. That’s what happened ...

Today Nvidia announced CUDA 6, the latest version of the company’s pervasive parallel computing platform and programming model. Designed to make parallel programming easier than ever, Cuda 6 will help ...
