Si570 Set Frequency

Alfredo Mendiola Loyola
 

Hello:

I have found this Arduino code to set the Frequency on a si570 oscillator but it has a max frequency of 157 Mhz (#define ULIMIT 157000000UL),

Is there a way to modify the source code to make it work until 440 Mhz ?

I would like to set frequencies from 430 to 440 mhz.
