embeddedcUsing volatile to Guard Hardware Registers in Embedded C
Learn why the volatile qualifier is essential for reliable hardware register access in Embedded C, see a GPIO LED toggle example, and understand the performance trade‑offs of over‑using volatile.
Static Allocation vs Dynamic Memory in Embedded C: A Practical Guide to Deterministic Systems
Choosing static allocation over dynamic memory in embedded C guarantees deterministic timing and prevents heap fragmentation. This guide shows why, with a UART ring‑buffer example, how to place data in Flash, align structures, and verify placement via the linker map.
Embedded C volatile: A Decision Guide for Memory-Mapped Register Access
Learn when to apply volatile to hardware registers in embedded C, how it interacts with compiler optimizations and multi-core ordering, and how to validate the generated code and target behavior.
Handling Asynchronous Events with Hardware Interrupts on Arduino AVR
Learn how to use hardware interrupts on Arduino AVR boards to capture asynchronous events instantly, avoiding the latency and missed triggers associated with polling.
Reducing CPU Overhead with DMA on ARM Cortex-M
Learn how to use DMA on ARM Cortex-M microcontrollers to eliminate interrupt storms and reduce CPU overhead during peripheral data transfers.
MATLAB Coder: Make the Function Codegen-Ready Before You Build
MATLAB Coder compiles a subset of MATLAB, so the real work is making a function statically typed and bounded before you touch build flags.
matlabBounded Binary Frame Parsing in Embedded C: An Allocation-Free Architecture Note
External bus frames are untrusted. This architecture note covers a static-buffer, allocation-free parser with length and CRC checks before internal state is updated.
Implementing Deterministic Interrupt Service Routines in Embedded C
Learn how to implement deterministic Interrupt Service Routines (ISRs) in embedded C, focusing on volatile variables, critical sections, and avoiding non-reentrant functions.
