Macro Definition Documentation
◆ CONFIG_ZTIMER_AUTO_ADJUST_SETTLE
| #define CONFIG_ZTIMER_AUTO_ADJUST_SETTLE 0 |
Some MCUs clocks need some warm-up time during which timing is inaccurate.
This can be a hindrance when using the ztimer_auto_adjust module.
- Warning
- This value will increase the boards start-up time
◆ CONFIG_ZTIMER_USEC_ADJUST_CLOCK_START
| #define CONFIG_ZTIMER_USEC_ADJUST_CLOCK_START 0 |
◆ CONFIG_ZTIMER_USEC_ADJUST_SET
| #define CONFIG_ZTIMER_USEC_ADJUST_SET 0 |
An offset for ZTIMER_USEC allowing to compensate for the offset of ztimer_set().
It can be measured with ztimer_overhead_set()
This value should be configured in the board.h.
◆ CONFIG_ZTIMER_USEC_ADJUST_SLEEP
| #define CONFIG_ZTIMER_USEC_ADJUST_SLEEP 0 |
An offset for ZTIMER_USEC allowing to compentsate for the offset of ztimer_sleep().
It can be measured with ztimer_overhead_sleep()
- Note
- As internally ztimer_sleep() uses ztimer_set() CONFIG_ZTIMER_USEC_ADJUST_SET should be tuned before.
This value should be configured in the board.h.
◆ CONFIG_ZTIMER_USEC_MIN
| #define CONFIG_ZTIMER_USEC_MIN (10) |
ZTIMER_USEC optimal minimum value for ztimer_set()
When scheduling an ISR every timer will be set to: max(CONFIG_ZTIMER_USEC_MIN, value).
This value only applies if the counter object used for ZTIMER_USEC is periph_timer. This is supposed to be defined per-device in e.g., board.h.
