The news site lwn just posted a guide on GCC inline assembly. The guide is written in plain colloquial language and is a great complement to GCC documentation on the matter, which is more of a reference of the various functionalities. I found that the extended form of inline assembly is a powerful way to use the machine special […]
This video is an introduction on what software is and what programmers do, and it’s great because it can be shared with everyone, especially those who know nothing or almost nothing about software. via Reddit.
Sticky Bits » Blog Archive » Developing a Generic Hard Fault handler for ARM Cortex-M3/Cortex-M4. This is a very informative post on Cortex-M fault handling. It covers basic handling up to examination of the context that produced the fault.
In this post I prepared what I think is the simplest example on how to manage interrupts for the widespread ARM926 core. From this example one can expand the complexity of the interrupt management at will. I’m going to test the functionality with QEMU, emulating the Versatile Platform Baseboard. I based this example on my […]
In embedded software programming there’s often the need to use assembly-level instructions to reach all the functionalities of the processing core. But when the developing is done almost exclusively in C, it is sometimes a burden, often an added complexity and possibly a nuisance to code separate assembly files containing the needed functions. Other than […]
