## What it is
A curated collection of study notes covering embedded Linux software and driver development, C language fundamentals, MCU development, IoT, and TCP/IP networking, organized as interview preparation material. It includes markdown documents and a wiki/blog with topics like data structures, ARM architecture, Linux internals, and FreeRTOS source analysis.

## Use cases
- prepare for embedded software engineer interviews
- review C language interview questions and pointer concepts
- study Linux driver development fundamentals
- learn TCP/IP protocol stack basics for embedded roles
- brush up on Linux commands, makefile, and shell scripting
- understand FreeRTOS internals and RTOS concepts
- review ARM Cortex-M architecture topics

## When to choose
- you are interviewing for embedded Linux, driver, or IoT positions
- you want concise Chinese-language notes on C, Linux, and networking fundamentals
- you need a quick reference for embedded systems concepts and peripherals like I2C, SPI, UART

## When to avoid
- you need a comprehensive step-by-step embedded tutorial for beginners
- you want up-to-date content, since the latest release was in 2022 and some sections are incomplete
- you need hands-on projects or runnable code rather than conceptual notes

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, developer-tools
- domain: embedded-systems, operating-systems, iot, tutorials, programming-languages
- platform: embedded
- tags: interview-preparation, embedded-linux, linux-drivers, freertos, mcu, tcpip, c-language, notes, cheatsheet, linux, arm
