embedded C

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 [...]

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 [...]

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 [...]

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. [...]

Over the last few months I’ve been working on projects using PIC microcontrollers. At first I had a rather negative view of the PIC processors. Since I started coding on them, I have come [...]

One of the projects I’m working on involves using capacitive touch sensing (CTS) on the TI MSP430.  TI has been pushing their touch sensing capabilities recently and has even released a [...]

For Valentine’s Day my son needed to make a “mailbox” for his kindergarten class. He & his mother made a rocket out of an old oat container. Since this was a family project, [...]

When using the ADC10 in an MSP430 with multiple conversions, the ADC10BUSY bit will stay on even after the conversions are done. Trying to be a good little programmer and checking to make sure [...]
