If enabled, esp_timer_dump will dump information such as number of times the timer was started,
|
|
number of times the timer has triggered, and the total time it took for the callback to run.
|
|
This option has some effect on timer performance and the amount of memory used for timer
|
|
storage, and should only be used for debugging/testing purposes.

Configure the stack size of "timer_task" task. This task is used
|
|
to dispatch callbacks of timers created using ets_timer and esp_timer
|
|
APIs. If you are seing stack overflow errors in timer task, increase
|
|
this value.
|

Note that this is not the same as FreeRTOS timer task. To configure
|
|
FreeRTOS timer task size, see "FreeRTOS timer task stack size" option

in "FreeRTOS".

This sets the interrupt priority level for esp_timer ISR.

A higher value reduces interrupt latency by minimizing the timer processing delay.

to reduce latency but there is a disadvantage it leads to the timer ISR

running on every core. It increases the CPU time usage for timer ISRs

by N on an N-core system.

Allows using ESP_TIMER_ISR dispatch method (ESP_TIMER_TASK dispatch method is also avalible).
|
|
- ESP_TIMER_TASK - Timer callbacks are dispatched from a high-priority esp_timer task.
|
|
- ESP_TIMER_ISR - Timer callbacks are dispatched directly from the timer interrupt handler.
|
|
The ISR dispatch can be used, in some cases, when a callback is very simple
|
|
or need a lower-latency.
