WebDec 4, 2024 · Re: Atmega32U4 PORTD refuses to read inputs. « Reply #3 on: December 04, 2024, 04:35:55 pm ». I would suggest you first determine if it is a hardware or software problem. Run a much simpler test program to test the hardware. For example: WebPORTD = 0xFF; // prepare off-state for segments ⇒ PORTD = 0x00; PORTD = ~(digit[current_phase]); // Update segments ⇒ PORTD = digit[current_phase]; Frequency adjustment: The main reason to limit the current of LEDs is to prevent them from overheating. Pulsed current heats the LED only momentary, the shorter the pulse the …
