MCPWM frequency resolution

[Csavel99]

Hi,

Is there a way to get 0.1Hz or better resolution with the mcpwm hardver in arduino IDE? The set frq func only accepts uint32_t variable.
I want to use it for generating musical (midi) notes for witch 1Hz resolution is not enough.. It needs to be a low duty signal (less than 10%, few 100uS ontime) on low freqs (<2000Hz).
