If that title means anything to you, you’ve spent time on the internet trying to make RTT work for you. Read on for code to help you dynamically change if your RTT output blocks or not.

It’s not clear how to tell if a semaphore is taken in FreeRTOS, but it’s critical in troubleshooting some problems.

You’re being a good engineer and have this super awesome system that allows you to do remote code updates with code signing, etc. on your embedded processor. That’s awesome. [...]

Sometimes we want to individualize a piece of hardware.  We don’t want to recompile the whole program (because then it’s hard to verify that it is the same program), and we don’t want to [...]

While recently working on a project where we had included, nested, embedded, or inherited XSDs, I had errors while getting the XML to validate using LXML.  The solution ended up being that when [...]

One of this year’s projects was taking a CC2540 and making an interactive iBeacon with it.  This turned out to be more difficult than expected… which may explain recent design trends [...]

I took a look at capacitive touch sensing on the MSP430 in 2011 and it was a little… lacking. I had another project come up and had a chance to play around with it again a couple months [...]

This is just a quick snippet of code for you if you happen to be using a Blackfin BF51x processor and have some space and pins on an external FPGA to spare.

I’ve recently been reading up on software defined radio (SDR).  An epiphany that I had recently was that if we have sampled a signal so that we meet the Nyquist criteria, we can reproduce [...]

I had an interesting problem show up when I was working on a project at the beginning of the year.  It involved an Analog Devices Blackfin 51x series processor.  We went to transition to their [...]
