| - | Pentru a gestiona simultan display-ul, input-ul analogic și efectele vizuale/sonore fără să se blocheze, sistemul folosește intens perifericele hardware ale microcontroller-ului: | ||
| - | * **I2C (TWI):** Activat pe pinii PC4/PC5. Este configurat în **Fast Mode (400 kHz)** pentru a asigura transferul rapid al frame-buffer-ului către display-ul OLED (menținând ~30 FPS). | ||
| - | * **ADC:** Canalele ADC0 și ADC1 sunt folosite pentru citirea fluidă a joystick-ului, utilizând un prescaler de 128 pentru stabilitate. | ||
| - | * **Semnale PWM:** Timerele 0 și 2 generează semnale PWM hardware pe 3 pini independenți pentru a controla intensitatea și mixarea culorilor pe LED-ul RGB. | ||
| - | * **Timer1 (CTC Mode):** Generare de frecvențe hardware precise pentru notele muzicale transmise către buzzer, degrevând procesorul de folosirea funcțiilor blocante de tip delay. | ||
