The first part of this article described the conditions for an exception request to be accepted by a Cortex-M processor, mainly concerning the relationship of its priority with respect to the current execution priority. This...

Analyzing the Linker Map file with a little help from the ELF and the DWARF

Govind Mukundan

When you're writing firmware, there always comes a time when you need to check the resources consumed by your efforts - perhaps because you're running out of RAM or Flash or you want to optimize something. The map file generated by your linker is...

Ten Little Algorithms, Part 5: Quadratic Extremum Interpolation and Chandrupatla's Method

Jason Sachs

Today we will be drifting back into the topic of numerical methods, and look at an algorithm that takes in a series of discretely-sampled data points, and estimates the maximum value of the waveform they were sampled from.
