 How Does It Work?</h2>
 <p >The Rishka virtual runtime is a system designed to run special RISC-V binaries smoothly on ESP32-WROVER microcontroller units. Under the hood, the virtual machine serves as the main engine, while the kernel acts as its core component. The kernel handles system calls efficiently, providing a range of interfaces for accessing different system features and services.</p>
-<div align="center"> <img src="rishka-flow.png" alt="" class="inline"/> </div><p >These include basic functions like managing files, as well as more complex tasks like controlling GPIO pins, attaching and detaching interrupts, and communication protocols such as <a class="el" href="d6/d81/classI2C.html" title="Class for handling I2C operations in Rishka applications.">I2C</a> and SPI. Additionally, the kernel manages system utilities specific to the Jessy OS, handling tasks like sub-process runtime and memory allocation.</p>
