# 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
|
|
```
|
|
|
|
This test application also makes use of the `ztimer_auto_adjust` pseudomodule
|
|
and thereby allows for comparison of the offset values calculated during
|
|
auto-initialization and later during this test.
