To convey human intent to an electronic circuit, some form of input method is required. Turning on the power, changing ...

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, ...

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 ...

The 0- to 20-mA current loop isa reliable means of data communicationin industrial applications.These circuits use a precision shunt inthe receiver to convert the current signalinto a voltage signal.

Drawing and analysing flowchart diagrams involves elements like count, compare, macro, do macro, end, increments, decrements, and expressions. Microcontrollers (PICs) are used in control systems, ...

IC bus interfaces and bus controllers or bus masters are interfaces between most standard parallel-bus microcontrollers or microprocessors and the serial bus. There are many different types of IC bus ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

IC timers are programmable semiconductor circuits that generate or set timing for electronic circuits. These chips function as single or multi-function units. An IC timer works by charging and ...

[Lujji] is playing around with the STM8 microcontroller. In reviewing the official documentation for this chip, he read the external clock can be a sine wave, a triangle wave, or a square wave with a ...

Rising foundry and backend manufacturing costs are putting further pressure on chip designers, raising the prospect of another round of semiconductor ...
