10 Pain-free Steps to Configure an Interrupt Controller

Properly setting up interrupts on a microcontroller isn’t easy.  The number of times an engineer has setup interrupts in their career doesn’t seem to make a difference.  Configuring interrupts always has some gotcha hidden away that leaves the developer scratching their head and seeking answers in an obscure data sheet or online code snippet.  Thankfully … Continue reading 10 Pain-free Steps to Configure an Interrupt Controller

5 Tips for Getting Started with Digital Signal Processing (DSP) on Arm Cortex®-M CPUs

Digital signal processing (DSP) provides developers with the ability to clean-up and analyze complex signals in a flexible and cost-efficient manner all from software. When developers typically think about DSP, they often picture expensive, dedicated processors, but modern microcontrollers, such as the Arm Cortex-M processors, now include DSP extensions that allow DSP algorithms to be … Continue reading 5 Tips for Getting Started with Digital Signal Processing (DSP) on Arm Cortex®-M CPUs
