| - | The defining novel element of this software architecture is the **Custom Interrupt-Driven Kinetics Engine**. In standard hobbyist plotters, stepper motors are driven using blocking delay loops (e.g., ''_delay_ms()''), which paralyzes the microcontroller. In this project, the **Bresenham Line Algorithm** is deeply integrated into an AVR Hardware Timer Interrupt Service Routine (ISR). This allows the ATmega2560 to pulse the motors seamlessly in the background at exactly 4,000 Hz, while the main loop simultaneously parses complex G-code, updates the UI, and communicates over Serial without dropping a single physical step. | + | The defining novel element of this software architecture is the **Custom Interrupt-Driven Kinetics Engine**.
