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 ...

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 ...

*sigh*<BR><BR>So here's what the problem is. Part of my job requires me to reconfigure laser bar code scanners and recalibrate them in order to read a bar code at different speeds and angles. In order ...

The circuit in Figure 1 represents a simple and cost-effective way to obtain eight-channel analog-signal acquisition through a PC's LPT port. IC 1, a 12-bit, serial-output MAX187 ADC, operates from a ...

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 ...
