Changing External Clock Configuration on Kinetis_120MZ_SC

mithunp_s — Mon, 18 Nov 2013 21:11:28 GMT

Hi All,

My customer is using 30MHZ crystal in their target board and want to use UART0 for communication, I have downloaded Kinetis_120MZ_SC sample code and in the hello_Word program and in the Trw-K60F120M.h there is below settings, If I want to change the crystal value CLK1_FREQ_HZ to 30000000 & TERM_PORT to UART0 does it support.

Please let me know if other settings need to be configured

#define CLK1_FREQ_HZ 12000000

#define CLK1_TYPE CRYSTAL

/* Serial Port Info */

#define TERM_PORT UART5_BASE_PTR

Regards

Mithun

Hi, Mithun

Yes, you can change it. The reminder is please pay attention to baud rate changing. Thanks.

Best Regards

Paul

Hi Zhe Tian,

Thanks actually in my customer target board they are using MK60FX512 and the Kinetis_120MHZ_SC sample code are based on MK60FN1M0 please help me how can I port them/change them to work for MK60FX512.

Hi all,

I'm also looking for changing my project from MK60FN1M0 to MK60FX512.

But is there a real difference between the two target?

Because my project works on a MK60FX512 even if it's designed for a MK60FN1M0.

Can I have some trouble without changing the coonfiguration?

Regards,

Guillaume
