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 ...

Ok, the title is a bit misleading. Like most things in life, it really isn’t infinite. But I’m going to show you how you can use a very interesting Linux feature to turn one serial port from a ...

The setserial command will tell you the hardware parameters of your Serial port like the IRQ and hardware address. Though if you are looking to configure a device such as a Cisco router over that ...

A bootloader makes it possible to update a product’s firmware in the field. Common communication interfaces like UART, I 2 C, SPI or USB can be used to update the firmware, which typically involves a ...

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 ...
