Energy Micro Introduces EFM32 Wonder Gecko Microcontroller

Energy Micro EFM32 Wonder Gecko Microcontroller

Energy Micro introduced the EFM32 Wonder Gecko microcontroller. The EFM32 Gecko MCU features the ARM Cortex-M4 processor, which provides a full DSP instruction set and a dedicated floating point unit (FPU). The EFM32 Wonder Gecko also utilizes the eLL (extreme low leakage) process for low-power operation in active and sleep modes. The Wonder Gecko microcontrollers is available now for $2.64 each in 100k units.

White Paper: Minimizing Energy Consumption in Inductive Sensing Applications

By Anders Guldahl

Introduction

Sensing is all about the ability to detect or measure changes in physical properties. In the context of an electronic control system, the requirement is to translate a parameter such as temperature, pressure or movement into an electrical signal. While some sensors directly produce a voltage output, which provides the ideal input for a microcontroller-based system, the majority of sensors depend on resistive, inductive or capacitive circuit elements whose behavior varies according to a known characteristic. These sensors typically require an external circuit to convert their output into a measurable signal for capture by a microcontroller (MCU).

White Paper: How to Minimize Energy Consumption in Resistive Sensing Applications

Introduction

The ease with which resistance can be measured, coupled with the large number of simple, low-cost devices whose resistance changes with other physical properties, accounts for the wide range of resistive sensing applications. These include measuring temperature, pressure, humidity, position, displacement, etc. using electro-mechanical devices like potentiometers or other transducers such as thermistors and piezo-resistive strain gauges.

White Paper: How to Minimize Energy Consumption in Capacitive Sensing Applications

Introduction

Capacitive sensing is all about the ability to measure the capacitance, or more often the change in capacitance, between two or more electrodes. As a technique it is frequently employed to detect proximity or position but can also be used to measure humidity, fluid level and acceleration. Because capacitive sensing supports such a diverse range of applications, solutions are found in many different markets — from industrial, automotive and medical through to consumer. And as more and more electronic products are being designed with touchpads and touchscreens we are seeing an explosion in the use of capacitive sensing technology to provide the vital human machine interface (HMI).
