To obtain the time since boot, in microseconds, we use the function,esp_timer_get_time(). This function returns the number of microseconds sinceesp_timerwas initialized which gets started before the app_main() function. int64_t esp_timer_get_time(void) Code to get Timer Time (time in mi...

second using the function esp_timer_dump(). It takes in a single parameter which is the stream where the data will be dumped. This function will print the list of active timers according to the format: timer name, period of timer and time of the next alarm since boot in microseconds. ...
Re: esp_timer_get_time() and vTaskDelay() behaviour by Sprite » Fri Mar 01, 2024 5:38 am From the fact that OP gets 2000 microseconds, I imagine he changed the tick frequency to 1000Hz. OP: The reason is that ticks happen on a fixed schedule, once per MS in your case, see...
Enabling the ESP32 to wake up after a predefined time is very straightforward. In the Arduino IDE, you just need to specify the sleep time in microseconds in the following function: esp_sleep_enable_timer_wakeup(time_in_us) Code To program the ESP32 we’ll use Arduino IDE. So, you nee...
