A version of thie article appeared in the February 2012 issue of Test & Measurement World. See the PDF. Many industrial systems use the 4–20-mA loop to transmit measurements from sensors to displays, ...

Microcontrollers contain a broad range of features due to the numerous end-use markets they address. Typical microcontrollers come in 8-, 16-, and 32-bit versions and commonly are used in consumer, ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

Battery-charger-control designers face a fundamental choice: to use a part from the rich selection of dedicated charge-control ICs available from many vendors or to use a programmable microcontroller.

RECENTLY, SOME FRIENDS SENT ME AN SOS e-mail about interference that was being detected from a little automotive microprocessor device they had been shipping for years with no problems. They couldn’t ...

Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order ...
