Picolibc: A C Standard Library for Embedded Systems

Picolibc is a C standard library suitable for small microcontroller embedded systems, which can operate in low memory (RAM) devices. Picolibc is an upgraded version of “newlib-nano” that lacks a mature stdio lib, using a lightweight stdio lib from avrlibc, making it more suitable for low memory embedded devices. Zephyr introduced Picolibc in v3.3.0, and … Read more

Getting Started with ZephyrRTOS: Development Environment Setup

Although I personally prefer Rust, the Rust ecosystem does not yet have an embedded system with the structure/abstraction levels and rich ecosystem like ZephyrRTOS. I consider myself a pragmatic + idealistic engineer, so I chose to use the C/C++ based ZephyrRTOS with its rich ecosystem while also trying to integrate the Rust embedded ecosystem. Although … Read more
