RE: Is there a random number generation function and high-precision system time function that can be called directly？

Hello,

for timestamp purposes you can use the system clock or k_timer functionality in the Zephyr kernel API. Here's a link to the documentation.

For random number generator the sys_rand32_get() is the correct function to use. You need to remember to set the option

CONFIG_TEST_RANDOM_GENERATOR=y

in prj.conf.
