Modern embedded systems are becoming increasingly compact, power efficient, and feature rich. As SoCs integrate more functionality, developers need reliable debug access without increasing pin count ...

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 ...

Download the PDF of this article. These days, hardware debug interfaces like the Joint Test Action Group (JTAG) IEEE 1149.1 standard are ubiquitous. You can find them on many microcontroller and ...

Hopefully you know perfectly well what the software in your microcontroller is supposed to do. However, if you have been asking yourself why it doesn’t work as expected and wondered what it is ...
