Hey,
I was wondering if anybody can help point me in the right direction to drive a DC motor at approx 17850Hz
I also need to be able to continue to use TimerOne (With &Timer1) Library - although I may be willing to drop this if it's the only way to get what I need.
Thanks in advance.
Do you mean 17850 rpm?
Crikey, I don't even think my motor would be half capable of that speed.
17850Hz Frequency output, with PWM. 0~255.
Why is it that you believe you need a specific PWM frequency to drive a DC motor? Mostly higher freqs are used to get rid of hum, but are then spec'd at some arbitrary figure such as 40kHz.
I've basically replicated a board but the motor was running a 17850Hz. Anything lower than this and it just hums. I was using PWM Frequency library on a nano, but I need to switch over to a micro and the PWM Frequency doesn't work on that.
Which PWM library? Can you link a copy?
