In this article, I will explore:

• How Rust ensures memory safety in no_std environments
• What memory allocation strategies are viable on modern embedded targets
• Which patterns help minimize memory usage without sacrificing reliability
• The current state of Rust adoption in trustworthy embedded systems

🟠 If you work with hardware, write firmware, or are simply interested in the topic of memory safety, then this text is for you.

🟠 What is a general purpose input output (GPIO) of the MCU

Rust's approach to memory management is both powerful and complex.
🟠 In this article, I want to take a deep dive into how Rust handles memory for the type system under the hood, and try to answer questions like:

• Why can't we create purely dynamic types?
• How does the Rust compiler decide where and how to allocate memory for variables?
• What exactly does a pointer inside a fat pointer refer to, especially for string literals?
• And what role does libc play in this?

This article is the second part of my exploration into the stages and optimizations of Rust compilation, focusing now on embedded systems development.
Embedded environments impose unique constraints such as limited memory, lack of an operating system, and strict real-time requirements.
Consequently, compiling Rust code for these systems demands special considerations — from the removal of the standard library to precise target specifications and custom linker scripts.

🟠 Here, we’ll walk through the Rust compilation pipeline with a focus on how it adapts for bare-metal, resource-constrained embedded platforms.

The PN junction is the fundamental building block of many semiconductor devices, from diodes to transistors and solar cells.
Understanding how this tiny boundary between p-type and n-type materials controls the flow of electrical current is key to grasping modern electronics.

🟠 In this article, we’ll explore the structure, behavior, and biasing conditions of the PN junction — revealing the delicate balance that makes semiconductor devices work.

In embedded Rust development, minimizing the size of the compiled firmware is essential due to the limited memory resources of microcontrollers.
This article explores how to analyze binary sizes using the cargo size tool, the structure of ELF binaries produced during compilation, and the importance of linker scripts in controlling memory layout.

🟠 Focusing on the ARM Cortex-M0 target, we will discuss practical strategies to optimize and compress firmware for resource-constrained embedded systems.

Semiconductors play a crucial role in modern electronics, bridging the gap between conductors and insulators.
Understanding their unique properties is essential to grasp how everyday devices like diodes and transistors function.

🟠 In this article, we’ll explore the fundamental concepts of semiconductors, from atomic structure to crystal formation, and explain how doping transforms their electrical behavior.

Rust’s compilation process is a sophisticated journey that converts human-readable source code into highly efficient machine-executable binaries.
This multi-stage pipeline ensures Rust’s guarantees of memory safety, zero-cost abstractions, and concurrency without sacrificing performance.

🟠 In this article, we’ll explore each key step, from tokenization and macro expansion to borrow checking, LLVM optimizations, and final linking—revealing how Rust transforms your code into a reliable executable.
