Hi
I am trying to call the function "wiced_get_nanosecond_clock_value()" , but I get nothing.
I followed the same code used from apps.snip.
Please see attached code.
your help is really appreciated.
Thanks,
Ramzi

Hello,
Please have a look at this thread How to properly print a uint64_t on CYW43907
The function is returning the value but the format specifier used for printing the number seems to be giving the error.
You may print the unsigned long long int value by typecasting it to double and using the float identifier i.e., WPRINT_APP_INFO((" %f", (double)cpu_time_used));

Did you really test it?
uint64_t cpu_time_used = wiced_get_nanosecond_clock_value();
WPRINT_APP_INFO(("The time taken is %f \n", (double) cpu_time_used));
Above code prints below output:
The time taken is 0.000000

Yes Sir. I think you have not initialized the clock by calling platform_init_nanosecond_clock();
The console output is:

The code is:
wiced_init( );
uint64_t cpu_time;
platform_init_nanosecond_clock();
WPRINT_APP_INFO(("Printing nanosecond clock value\n"));
cpu_time= platform_get_nanosecond_clock_value();
WPRINT_APP_INFO(("cpu_time: %f\n", (double)cpu_time));

ok. It looks good after adding wiced_init_nanosecond_clock().
Thanks.
