Extra Notes for Kirin3 Labs from Freescale

Thu, 01 Oct 2009 07:24:04 -0000

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.

Jack Thompson is at it Again, This Time Suing Facebook

Thu, 01 Oct 2009 04:13:38 -0000

Despite being permanently disbarred by the Florida Supreme Court last year due to "abusive and frivolous filings", Jack Thompson is back. This time, however, he isn't going after the video game industry, but rather social networking juggernaut, Facebook.

How to use a digital signal controller (DSC) to drive a high-brightness RGB LED for a pixel board

Wed, 30 Sep 2009 17:16:33 -0000

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.

AMD's Ian McNaughton blasts NVIDIA over PC Game Issues

Wed, 30 Sep 2009 14:58:13 -0000

AMD's very own self-proclaimed bad boy Ian McNaughton took a direct swing at NVIDIA and The Way it's Meant to be Played program today in a blog post that is worth taking a look at. Ian calls out some issues with several TWIMTBP titles, which is something you don't see being done everyday. If you already own or are thinking about getting Batman: Arkham Asylum, Need for Speed: Shift or Resident Evil 5 then you might want to see what Ian is upset about.

AMD Announces More Radeon GPUs

Sat, 26 Sep 2009 06:31:00 -0000

In exactly one week from now, AMD is expected to launch its ATI Radeon HD 5850 and 5870 videocards, which as it turns out will be a precursor of more 5000 series cards to come. And you won't have to wait long, either.

USB solutions from Freescale

Thu, 24 Sep 2009 09:54:32 -0000

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

Sensorless PMSM Drive for Dishwasher Pump Using Freescale MC56F8006 Device 2/2

Tue, 22 Sep 2009 10:32:00 -0000

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.
