Understanding and using No-OS and platform drivers
This article describes the use of no-OS (no operating system) drivers and platform drivers for building application firmware. Rapidly advancing technology needs software support (firmware…
Manipulating C strings safely
Here’s a simple mechanism to prevent software from manipulating an invalid string with well-known string functions. A software failure due to an invalid string of…
Protecting your embedded software against memory corruption
The aim of this article is to provide a software method that explains how to deal with corruption of memory data sets stored in non-volatile…
Software quality demands both static code analysis and dynamic testing

Accelerating atomic synchronization
Synchronizing multiple cores on a single chip or in a system requires atomic operations and hardware that enforces these operations. Synchronization The motivation for atomic…
Best practices for debugging Zephyr-based IoT applications
The Linux Foundation Zephyr Open Source Project has grown into the backbone of many IoT projects. Zephyr offers a best-in-class small, scalable, real-time operating system…
Random interrupts in multicore scenarios
How do you catch random interrupts or have control of the interrupt handling when applications are very complex? The demand for complex applications is increasing…
Open-sourcing a more precise time appliance
Facebook has developed an open source time appliance for timing infrastructure, which can be used by anyone to build their own time card for a fraction of the cost of a regular time appliance.
Achieving full MCU partition isolation: Heaps
Achieving full microcontroller (MCU) partition isolation is essential for achieving high security for MCU-based systems. Continuing a series on this complex topic, this article discusses…
