This works great, the buzzer immediately sounds. The issue is turning it off! Common sense says pio7=0 should work, but no luck. I’m currently setting pwmf=65535 to make the buzzer inaudible, but this limits pwm functionality on pins 4 through 6. Reconfiguring pin 7 as an input also works to silence the buzzer, but this seems clunky. Is there a better way?
Hi…the option of controlling the fan speed and the satisfaction of silent computing were not always present when it comes to personal computers. The early x86 computers did not have active cooling because not much heat was generated, right until the introduction of the first 486 models. From that time and up until now, the computer power consumption and thermal dissipation have grown exponentially, as well as their performance.
