Open-source alternatives to Embedded Diagnostic Logger

spdlog is a high-performance C++ logging library designed to record diagnostic messages and application events. It serves as an asynchronous logging framework and thread-safe library that coordinates access across concurrent threads to maintain message integrity. The project functions as a multi-target log router, distributing single events to multiple destinations such as consoles, files, and system daemons. It includes a log rotation manager that handles file lifecycles through basic, rotating, or daily rollover strategies to prevent disk exhaustion. The library covers a broad range of cap

WORK IN PROGRESS! Some things may still be buggy. Issues and pull requests are welcome. Additional tests are also very much welcome.

Minimal printf() implementation for embedded projects.

EasyLogger is a lightweight C/C++ logging library and asynchronous framework designed for embedded systems, IoT devices, and wearables. It functions as a resource-efficient logger and flash memory manager, providing tools for low-level debugging and system event recording with minimal ROM and RAM requirements. The project distinguishes itself through an asynchronous logging model that buffers messages to a separate thread, preventing logging operations from blocking real-time application execution. It includes a specialized flash memory manager that utilizes circular buffering to persist logs

This log system is thinked for embedded systems with mininmal resource utilization. The log system is designed to minimize memory compsumition in flash or RAM, enable an eficient in-ram loggin buffer with very efficient storage.

This project is a lightweight C string formatting library and low-level text formatter designed for embedded systems and bare-metal hardware environments. It provides a minimal formatting engine for converting numeric types and variables into formatted text using standard specifier notation in environments that lack a full C runtime or standard library. The library features a custom stream output utility that routes formatted text strings to user-defined callback functions. This allows for flexible output destinations and character-level writing, enabling formatted debug messages and logging

xprintf is a compact string I/O library. It is ideal for tiny microcontrollers that has insufficient program memory for regular printf function. The recommended use is: writing formatted strings into LCD or UART and for debug/maintenance console.

embedded-log 是一个小巧漂亮的嵌入式日志库。具有彩色输出，可指定日志信息输出到串口、屏幕、FLASH或者通过usb输出到pc上。使用c语言编写，可用于C51、arm等设备上。

A safe and fast high-level and low-level character input/output library for bare-metal and RTOS based embedded systems with a very small binary footprint.

printf for embedded system with floating point support.

Embedded-hal is a hardware abstraction layer for embedded microcontrollers that defines common traits allowing peripheral drivers to remain entirely independent of specific hardware platforms. The library provides platform-agnostic interfaces that decouple driver logic from microcontroller architectures, utilizing zero-cost trait abstractions that compile down to direct hardware register manipulations without runtime overhead or memory allocation. The project features asynchronous execution support and synchronous-to-asynchronous adaptation, enabling non-blocking peripheral operations and coo
