I blog on my projects, and occasionally on other topics such as wealth creation. Popular posts are Building an Embedded Asterisk PBX, Building a BlackfinOne, the Open Source Echo Canceller series and my philosphical rant on Open Source Hardware.
Over the past 3 years I have been done a lot of work with the Blackfin. Using the blog I have captured a lot of practical information and tips on Blackfin code optimization.
