+# RTOS Sample Project for Raspberry Pi Pico 2 (Multicore)
+
+This project demonstrates a hybrid implementation of FreeRTOS and Bare-metal execution on the Raspberry Pi Pico 2 (RP2350), utilizing both processor cores.
+
+## Project Description
+The project showcases how to run a Real-Time Operating System (FreeRTOS) on one core while maintaining a high-precision hardware-timer-driven process on the second core.
+
+### Core 0: FreeRTOS
+Core 0 runs the FreeRTOS scheduler and manages multiple concurrent tasks:
+1. **LED Blink Task**: Uses a custom C++ class `Pico2LED` to toggle the built-in LED every 200ms.
+2. **USB Print Task**: Prints the system status to the USB serial console every 1 second, including counters from both cores.
+
+### Core 1: Bare-metal (Hardware Timers)
+Core 1 operates in a bare-metal mode to ensure maximum predictability and precision:
+- It creates a dedicated **Hardware Alarm Pool**.
+- It runs a **Repeating Timer** that increments a global counter every 1000ms via a hardware interrupt.
+- The core remains in a low-power state (`__wfi`) until the next interrupt occurs.
+
+## Algorithm Description
+The project implements a multi-core synchronization and execution flow:
+
+1. **Initialization (Core 0)**:
+   - Initialize standard I/O.
+   - Launch Core 1 using `multicore_launch_core1()`.
+2. **Bare-metal Execution (Core 1)**:
+   - Initialize a hardware alarm pool specifically for Core 1.
+   - Schedule a repeating timer interrupt.
+   - Enter a loop of "Wait For Interrupt" (`__wfi`).
+3. **RTOS Execution (Core 0)**:
+   - Create FreeRTOS tasks for LED control and USB logging.
+   - Start the scheduler via `vTaskStartScheduler()`.
+4. **Inter-core Communication**:
+   - Core 0 reads the `core1_counter` variable (marked as `volatile` to prevent compiler optimization) to display the hardware timer\'s progress.
+
+## Installation and Setup
+
+### 1. Prerequisites
+Ensure you have the Raspberry Pi Pico SDK installed and configured.
+
+### 2. FreeRTOS Sources Setup
+```bash

+### 3. Build Process
+
+1. `mkdir build && cd build`
+2. `cmake ..`
+3. `make`
+4. Flash the `.uf2` file to the Pico 2.

+# Пример проекта RTOS для Raspberry Pi Pico 2 (Многоядерность)
+
+Этот проект демонстрирует гибридную реализацию FreeRTOS и Bare-metal выполнения на Raspberry Pi Pico 2 (RP2350), используя оба ядра процессора.
+
+## Описание проекта
+Проект показывает, как запустить операционную систему реального времени (FreeRTOS) на одном ядре, сохраняя при этом высокоточный процесс на базе аппаратных таймеров на втором ядре.
+
+### Ядро 0: FreeRTOS
+Ядро 0 запускает планировщик FreeRTOS и управляет несколькими параллельными задачами:
+1. **Задача мигания светодиодом (LED Blink Task)**: Использует пользовательский C++ класс `Pico2LED` для переключения встроенного светодиода каждые 200 мс.
+2. **Задача вывода в USB (USB Print Task)**: Выводит статус системы в USB-консоль каждую секунду, включая счетчики с обоих ядер.
+
+### Ядро 1: Bare-metal (Аппаратные таймеры)
+Ядро 1 работает в режиме bare-metal для обеспечения максимальной предсказуемости и точности:
+- Создает выделенный **пул аппаратных прерываний (Alarm Pool)**.
+- Запускает **циклический таймер**, который увеличивает глобальный счетчик каждые 1000 мс через аппаратное прерывание.
+- Ядро находится в режиме низкого энергопотребления (`__wfi`) до наступления следующего прерывания.
+
+## Описание алгоритма
+Проект реализует поток синхронизации и выполнения между ядрами:
+
+1. **Инициализация (Ядро 0)**:
+   - Инициализация стандартного ввода-вывода.
+   - Запуск Ядра 1 с помощью `multicore_launch_core1()`.
+2. **Bare-metal выполнение (Ядро 1)**:
+   - Инициализация пула аппаратных прерываний специально для Ядра 1.
+   - Планирование циклического прерывания таймера.
+   - Вход в цикл ожидания прерывания (`__wfi`).
+3. **Выполнение RTOS (Ядро 0)**:
+   - Создание задач FreeRTOS для управления LED и логирования в USB.
+   - Запуск планировщика через `vTaskStartScheduler()`.
+4. **Межъядерное взаимодействие**:
+   - Ядро 0 считывает переменную `core1_counter` (помеченную как `volatile` для предотвращения оптимизации компилятором), чтобы отобразить прогресс аппаратного таймера.
