## About 🚀

- **MOS** is a Real-Time Operating System (RTOS) project built in C++/Rust, which consists of a preemptive kernel and a command-line shell with other applications (e.g., **GuiLite** and **FatFS**).

- [**Renode**](https://renode.io/) is a virtual development tool created by [**Antmicro**](https://antmicro.com/) for multi-node embedded networks (both wired and wireless) and is intended to enable a scalable workflow for creating effective, tested and secure IoT systems.

> - Simple command-line interaction `Shell::{Command, CmdCall, launch}`
> - `HAL::STM32F4xx::SPI_t` and `Driver::Device::ST7735S_t`, porting the `GuiLite` graphics library
> - Blocking delay with `Kernel::Global::os_ticks` and `Task::delay`
> - Refactored project organization into `{kernel, arch, drivers}`
> - Support for `GCC` compilation, compatible with `STM32Cube HAL`
> - Real-time calendar `HAL::STM32F4xx::RTC_t`, `CmdCall::date_cmd`, `App::Calendar`
> - `idle` uses `Kernel::Global::zombie_list` to reclaim inactive pages
> - Three basic page allocation policies `Page_t::Policy::{POOL, DYNAMIC, STATIC}`


📦 `v0.1`

> ✅ Done:
> 
> - Basic data structures, scheduler, and task control, memory management
>
> 📌 Planned: 
>
