Depends on the SDK you are using. In HAL 0.6.0 - HAL_Delay(1000). In W80x-SDK you can pull the delay() function from iperf_timer.c
It usually works in microseconds. But delay maybe not less than 1 milliseconds. It will look like this for you
extern int delay(int us);
//your code
int ms = 1000; //1s = 1000 ms
delay(ms*1000); // in uS
//your codeIf you need to call a specific function every 1 second, you can use vApplicationTickHook or RTOS timers
For example
in vApplicationTickHook() you can creat a counter
Or create a separate RTOS task
