Now I am using nrf9160DK for development. In my project, I need to use a random number generator and a highly accurate system time stamp. Is there an API that I can call directly? If so, can you tell me the API name, calling method, and header files that need to be used. For the random number generator, I have tried to call the function sys_rand32_get (), but I get the following error during the build. Is it because the header file I added is incorrect?
In function `main ': /opt/sourcecode/ncs/nrf/samples/nrf9160/helloworld/build/../src/main.c:8: undefined reference to `sys_rand32_get ' collect2: error: ld returned 1 exit status %
Here are the header files I added.
#include <zephyr.h> #include <random/rand32.h> #include <misc/printk.h> #include <stdio.h> #include <stdlib.h>
Best wishes!
