4SkinOS

4SkinOS is a custom operating system for ESP32 microcontrollers, built on top of FreeRTOS and the ESP-IDF framework. It provides a shell interface, basic filesystem operations, and a platform for embedded application development.

Features

Custom operating system for ESP32
Interactive shell interface
In-memory filesystem with basic operations
Task management and scheduling (leveraging FreeRTOS)
Hardware abstraction layer (utilizing ESP-IDF)

Architecture

4SkinOS is structured as follows:

Hardware: ESP32 microcontroller
Low-level drivers: ESP-IDF framework
Real-time kernel: FreeRTOS
Operating System: 4SkinOS
- Shell interface
- Filesystem management
- Task and resource management
- System calls and APIs

While 4SkinOS uses FreeRTOS and ESP-IDF, it extends their functionality to create a complete, custom operating system environment.

Getting Started

Prerequisites

ESP-IDF (Espressif IoT Development Framework)
ESP32 development board

Building and Flashing

Clone the repository:

git clone https://github.com/yourusername/4SkinOS.git
cd 4SkinOS

Set up the ESP-IDF environment:
```
. $HOME/esp/esp-idf/export.sh
```
Configure the project:
```
idf.py menuconfig
```
Build the project:
```
idf.py build
```
Flash the project to your ESP32:
```
idf.py -p /dev/ttyUSB0 flash monitor
```
Replace /dev/ttyUSB0 with the appropriate port for your system.

Usage

Once flashed, the system will boot into a shell interface. Available commands include:

help: Show available commands
reboot: Reboot the system
ls [path]: List files in the current or specified directory
cd <path>: Change current directory
pwd: Print working directory
mkdir <path>: Create a new directory
touch <filename>: Create a new file
write <filename> <content>: Write content to a file
read <filename>: Read content from a file
rm <path>: Delete a file or empty directory
