Martin Bates' Refresher Course in Sensor Design using Microcontrollers

Embedded.com is running a multi-part series by Martin Bates, a lecturer in technology at the Hastings College of Arts and Technology, United Kingdom. In the series, Martin Bates provides details on the design the interface between a sensor and a microcontroller, and how to specify the performance of the linear amplifier used to translate the sensor output into suitable input for an MCU.

Part 1: An introduction to sensors and their characteristics
Part 2: A survey of sensor types
Part 3: Implementing a sensor/MCU interface

Embedded.com is running an article by Keith Curtis, a principal applications engineer at Microchip, on building simple MCU state machine constructs.

A simple construct, called a state machine, simplifies the task of generating a sequence by breaking the sequence into a series of steps and then executing them sequentially. While this sounds like an arbitrary definition of a linear piece of code, the difference is that the individual sections, or steps in the sequence, are encoded within a SWITCH/CASE statement.
