How to change Internal oscillator frequency to 24MHZ on LCP 11C14?

I wan to achieve maximum possible speed on LPC11C14. Need is to update LCD with Maximum rate.

I am using LPC open libraries on LPC expresso.

Please suggest changes for above requirement.

 

Also I have tried to connect 24MHz Crystal but with this crystal firmware is not working. If I connect 12MHz crystal it is working fine.

 

How to calculate time taken by one Machine cycle on LPC11C14?

 

Thanks,

KBalar

Hi,

Internal IRC is 12Mhz, you may use PLL to generate 24Mhz from 12Mhz.

Thank you!

Thank you!
