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.

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

[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 ...
