Implementing a modular high-brightness LED matrix. The software was divided into simple modules that implement certain functionalities or features.

This article will shortly recall the basics of SPI, it will also explain how to design a portable software driver in C language, and it will show a few waveforms of the SPI signals generated by the software driver.

Freescale offers many documents for its latest connectivity microcontroller Kirin3, MCF52259. I believe most of the people will start to evaluate the labs without reading the documents. I am one of these guys who hate reading documents. However, it is worth to read the document if you have no experience on CodeWarrior and ColdFire.

High-brightness RGB LED popularity for lighting applications is increasing as the cost of these devices becomes more attractive. However, this type of component brings different design complexities when compared to regular LEDs. To efficiently drive high-brightness LEDs, a switched power supply is required and a color mixing algorithm must be implemented. This article describes a simple application in which a digital signal controller (DSC) is used to drive a high-brightness RGB LED for a pixel board, several of which are connected on a network to create an RGB matrix.

You can select a wide range of core speeds for the Freescale USB micros, ranging from 2.1 MIPS to 410 MIPS. Of course, the high speed cores offer the USB feature only as a very small subset of the total features and peripherals. This possibility makes the Freescale USB products quite versatile, allowing them to find themselves in the most various applications

Generally, the "estimator" is defined as a dynamic system that estimates state variables. There are basically two forms of the estimator implementation: open-loop and closed-loop. In the case of the closed-loop estimator, the error between estimated and measured state variables is used as a correction term to adjust the response of the estimator. The closed-loop estimator is also referred to as an observer.

Using a highly-integrated microcontroller running "StickOS BASIC", it is possible to quickly build a toaster oven temperature profile controller for performing surface mount (SMT) printed circuit board reflow soldering at home.

Car door keypads have traditionally comprised of micro-switches that directly carry the motor currents used to operate windows and mirrors. In the case of electrically operated folding mirrors, a single multiple contact switch unit controls six motors in both directions.

There are too many choices available in the embedded market. In order to develop a good product and release it within schedule, the engineering team has to reply on a mature and affordable platform, or ecosystem. Because the dependency is so tight and system becomes more complex, it is hard to change from one to another. The success or failure for an embedded product has been decided from the very beginning. That is also the reason why Freescale presents MQX solution with Kirin3. However, it is not a bad idea to check out the alternative solutions.

The Flexis QE128 microcontrollers form the connection point on the Freescale Controller Continuum, where complimentary families of 8-bit S08 and 32-bit ColdFire V1 microcontrollers share a common set of peripherals and development tools to deliver the ultimate in migration flexibility.

Welcome to the training module on Intersil ISL6257 (datahseet) battery charger. This training module introduces the operation and application of the ISL6257 battery charger.

It is quite difficult for a designer to select a suitable one from hundreds of microcontrollers for his project.

The FAN5307 (datasheet) Evaluation Board is a compact circuit including the FAN5307 S18X, S15X or SX in a SOT-23 package

The Flexis MCU family represents an additional and important step in the direction of innovation and continuity: it brings to life the Controller Continuum.

Successful removal of the excessive current and consequent back emf present at the end of the commutation period for a brushless DC motor results in improvements in efficiency, reduced component cost and lower acoustic noise.

Wireless routers are very cheap and have been widely deployed in SOHO and public WiFi hotspots. Many routers can be upgraded or enhanced by different firmware distributions.

ESD (Electrostatic Discharge) is one of the main enemies of electronic devices. The term is used to describe the phenomenon which appears between two objects at differently electrical potentials.

This tutorial from Intersil, a world leader in the design and manufacture of high-performance analog semiconductors, explains how you can eliminate redundant connectors by using a single switch tha...

Let us explore how to install a full Debian distribution on an emulated ARM926 machine with QEMU. The consumer now have alternative choices for their devices. On the other hand, the developers can leverage the native compiler coming with the ARM Linux distribution to build their projects with less effort. No more cross-compiler is necessary now. You can also setup a build farm to speed up your native build with distcc. The development requirement is almost identical to the desktop system.

These five survived a year long competition where nearly 400 contestants created embedded systems based on Microchip's new 32bit PIC32 microcontroller family and over 9000 community members participated in blogs and in forums on the interactive website mypic32.com.
