programming

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 [...]

One of the projects I’m working on I chose to use one of the new Freescale KL25 MCUs.  They have an ARM Cortex-M0+ core and lots of peripherals to boot, including ones specifically designed [...]

… or how to edit a .hex file instead of recompiling it for every option. I had a product a while back where the customer needed to program it, but we didn’t want them to have to [...]

We had a bug that just wouldn’t go away. Sometimes it would show up quickly, sometimes it would show up after the code had been running for a few days… but it would show up. [...]
