Free UK Delivery on Eligible Orders If your ESP32 project has access to the Internet, you can get date and time using Network Time Protocol (NTP) - you don't need any additional hardware. Note: there's an easier and updated guide to get date and time with the ESP32 with the pre-installed time.h library: ESP32 NTP Client-Server: Get Date and Time (Arduino IDE) I think it's possible to make something with time and getTimeSinceStart but I suppose I'll lose some precision, if there is not other way it's what I'll do. Code: Select all. int64_t xx_time_get_time () { struct timeval tv; gettimeofday (&tv, NULL ); return (tv.tv_sec * 1000L L + (tv.tv_usec / 1000L L)); } Top

The settings for the system time source are as follows: RTC and high-resolution timer (default) RTC. High-resolution timer. None. It is recommended to stick to the default setting which provides maximum accuracy. If you want to choose a different timer, configure CONFIG_ESP32_TIME_SYSCALL in project configuration To get date and time with the ESP32, you don't need to install any libraries. You simply need to include the time.h library in your code. The following code gets date and time from the NTP Server and prints the results on the Serial Monitor. It was based on the example provided by the time.h library The client device such as ESP32 connects to the server using the User Datagram Protocol (UDP) on port 123. A client then transmits a request packet to a NTP server. In response to this request the NTP server sends a time stamp packet. A time stamp packet contains multiple information like UNIX timestamp, accuracy, delay or timezone The FRC2 is a legacy option for ESP32 until v4.2, a 32-bit hardware timer was used. Starting at v4.2, use the new LAC timer option instead, it has a simpler implementation, and has smaller run time overhead because software handling of timer overflow is not needed. Timer callbacks can dispatched by two methods uint32_t esp_log_timestamp (void) ¶ Function which returns timestamp to be used in log output. This function is used in expansion of ESP_LOGx macros. In the 2nd stage bootloader, and at early application startup stage this function uses CPU cycle counter as time source. Later when FreeRTOS scheduler start running, it switches to FreeRTOS tick count

All the timers are based on 64 bits counters and 16-bit prescalers. The prescaler is used to divide the frequency of the base signal (usually 80 MHz), which is then used to increment or decrement the timer counter The ESP32 reads temperature using the DS18B20 temperature sensor. After getting the temperature, it makes a request to an NTP (Network Time Protocol) server to get date and time. So, the ESP32 needs a Wi-Fi connection. The data (temperature and timestamp) are logged to a microSD card Sometimes an NTP server on your own local network can come in very handy. As well as situations where your network is cut off from the Internet but various pieces of software need a time reference, there are also cases where you are developing a project that requires the ability to fetch time data over the Internet, but you would ideally like to create custom NTP data In this tutorial we'll show you how to get date and time using the ESP32 and Arduino IDE.
