Serial-data links embed clocks in their data streams, and those clocks must be recovered at the receiver end. This Design Idea describes a data/clock-recovery algorithm for an NRZ (non-return-to-zero) ...

Outputting data from a microcontroller over a serial port is convenient and easy, but formatting, visualizing, and analyzing the data can be tedious and frustrating. [Alex Spataru] knows this all too ...

When looking at protocol information on a bus, an oscilloscope may not be the first instrument to come to mind�until now. As most engineers know, digital oscilloscopes are an indispensable ...

This application note presents data transfer between serial link and TCP/IP link using eZ80F91 microcontrollers. The application runs the Zilog TCP/IP (ZTP) Software Suite and accepts the incoming ...

We’re always excited to get a new chip or SIM card to interface, but our enthusiasm is often dampened by the prototyping process. Interfacing any chip usually means breadboarding a circuit, writing ...

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 ...

Electronics is everywhere, especially these days. Many times, as frequent users, we do not even notice a “paradigm change” in the things we use on regular basis. We use a fridge, but we do not care ...
