# Introduction This test application sets up a ztimer_periph at 1MHz, then measures 1024 times how much overhead ztimer adds. It uses the "ztimer_overhead_set()" function. See it's documentation for more information. It then sets `adjust_set` parameter and sleeps 1024 times and measure how much overhead ztimer_sleep adds. It uses the "ztimer_overhead_sleep()" function. See it's documentation for more information. At the end of the test `adjust_set` and `adjust_sleep` values are printed that can be set for the target `BOARD` in `board.h`. e.g for dwm1001: ```shell ZTIMER_USEC adjust params for dwm1001: CONFIG_ZTIMER_USEC_ADJUST_SET 6 CONFIG_ZTIMER_USEC_ADJUST_SLEEP 21 ```
