I am looking for a way to get the time since boot with nanoseconds precision. Currently, the best I can do is esp_timer_get_time() which returns time with microsecond precision. I connected my board to an oscilloscope and found out that it takes around 1.29 us for the esp_timer_get_...
In this tutorial we will learn how to get the date and time from NIST TIME server using M5Stack Core ESP32 and Visuino, Watch the video! Step 1: What You Will Need M5Stack Core ESP32more info here Wifi Internet connection or a Wifi HotSpot ...
I am looking to get time with nanoseconds precision. I know the function esp_timer_get_time() gives time in microseconds. I was hoping that I can modify it. Where can I find the source code/documentation to how it works.? ThanksESP...
Learn how to request date and time from an NTP Server using the ESP32 with Arduino IDE. Getting date and time is useful in data logging projects to timestamp readings. To get time from an NTP Server, the ESP32 needs to have an Internet connection and you don’t need additional hardware...
