Debug Trick Uses CPU Cache as RAM

Embedded tool company Asset Intertech is giving away a free e-book that teaches a clever little debugging trick: Use your CPU’s on-chip cache like RAM so you can bring up a non-functional board. If your new hardware won’t even boot, it’s hard to figure out where the hardware/software problem(s) lie. With no working RAM you can’t even run diagnostic routines. But your processor’s on-chip cache is always there and always reliable. Give it a shot. The download link is at http://bit.ly/XzK0nI.

As you probably know, discrete wire component data is quite a bit different than just standard socket and terminal mating relationships. When we look at how Samtec approaches discrete wire products, there are several components involved. We not only sell the assemblies, but w...

RedFit IDC SKEDD Connector

Sponsored by Wurth Electronics and Mouser Electronics

Why attach a header connector to your PCB when you really don’t need one? If you’re plugging a ribbon cable into your board, particularly for a limited-use function such as provisioning, diagnostics, or testing, it can be costly and clunky to add a header connector to your BOM, and introduce yet another component to pick and place. Wouldn’t it be great if you could plug directly into your board with no connector required on the PCB side? In this episode of Chalk Talk, Amelia Dalton chats with Ben Arden from Wurth Electronics about Redfit, a slick new connector solution that plugs directly into standard via holes on your PCB.
