Hello, Im using the ATTINY85-20U IC PWM pins 5 & 6 in an audio circuit, is there a way to change the frequency of both pin to be over 30Khz, (Out of human hearing). This code which i found on a forum somewhere changes the pwm of pin 5 to around 31khz, but it doesnt affect pin 6. I need both to be …

Don't use pinMode() and analogWrite(). void setup() { DDRB |= 0x03; // This is an alternative to pinMode() TCCR0A = 0xA1; TCCR0B = 0x01; } void loop() { OCR0A = 0; // This is an alternative to analogWrite to pin 5. but 0 is outputs continuous LOW. OCR0B = 1; // This is an alternative to …

Perhaps your ATtiny85 is running at 1MHz instead of 16MHz
