A PC’s serial port provides signal lines that you can use to expand the number of input signals. With some additional circuitry tied to these lines, you can use the port to test digital TTL ...
The circuit shown in Figure 1 provides a simple, low-power means of digitizing analog signals and sending the data directly to a PC's serial port where it can easily be read, analyzed, and stored. The ...
Practically everything you design these days includes some kind of serial interface. In fact, it’s hard to name something without a serial I/O port. Some of the more popular varieties are RS-232, ...
A PC’s serial port provides signal lines that you can use to read voltage levels of digital circuits. You can use the port to test digital TTL (transistor-to-transistor-logic)-level circuits. You just ...
