Hi everyone. running a nano with pwm freq set to 31khz (i think it is) on pins 9 and 10 to run some fans. I also need pin 8 at a higher freq but i dont know how to do it.
below is the code im using for pin 9 and 10. any help would be much apprecited. Thank you.
//chnages PWM frequency to eliminate fan noise - pins D9 and D10 - 31.4kHz
TCCR1A = 0b00000001; // 8bit
TCCR1B = 0b00000001; // x1 phase correct
Pin 8 on Nano is not a PWM pin.
derrrr lol my bad.
make it pin 11 then
change again to pin 6
In this tutorial there is a table of all options for setting PWM frequencies for Atmega328. Please note that different timers need to be configured for different pins.
yep. great read. Thankyou!!!!
