How to Configure MQX for ColdFire - 0 views

  •  
    Freescale offers complementary MQX RTOS suite for its ColdFire microcontroller with full source code. Although the software is deliveried in source code, it is highly recommended not touching source code in the component level. Freescale suggests designer using a user configuration file to configure the operation system in compile time.

Audio Reproduction on HCS12 Microcontrollers with Pulse-Width Modulation (PWM) Capability - 1 views

  •  
    .WAV files have a standard format that contains sample data and a header describing the format and contents of the file. It is important to check the format of the file to be downloaded to the HCS12 MCU, as reading a file of an unexpected format will result in corrupt sample data. Reading the value of a number of the parameters stored in the header and comparing these to the values expected authenticates the format of the file. This is the method used to check the validity of the .WAV file in the accompanying example source code.

Technology Behind Xbox 360 Project Natal - 0 views

  •  
    Much has been said about Microsoft's Project Natal since its announcement in the 2009 Electronic Entertainment Expo (E3) last June 1. "Natal" was used as the code name of the project because natal means birth and Microsoft considers the latest Xbox 360 video game device as the next generation home entertainment system. It utilizes a motion sensor device that will eliminate the need for a traditional controller and lets the gamer use his full body to interact with the device while gaming.

Replacing Batteries with Energy Harvesting Methods - 0 views

  •  
    Energy harvesting has been around us for centuries. Before electricity was invented people used the windmills and watermills to ease up their work, or even the solar energy to heat water in metallic cisterns. Besides being eco-friendly, these methods would have provided free energy and virtually inexhaustible source.
