In the development of ESP32 projects, time management is crucial. It allows you to precisely control program execution, complete scheduled tasks, log data, and even implement complex timing functions. The ESP32Time library has emerged to provide a series of convenient APIs, enabling developers to easily retrieve and set the time of the ESP32’s internal RTC, … Read more
RTC: Real Time Clock. In previous projects, an external clock chip was often used. With the growth of demand and technological advancements, many MCUs now integrate the RTC (Real Time Clock) module internally.This article describes the usage of the RTC module in conjunction with the e2 studio development environment and the RA8D1 microcontroller. Preparation 1 … Read more
Hello everyone, I am the Intelligence Guy~ Today, I will mainly share with you the synchronization issues between the Linux system time and the RTC. In a Linux system, the hardware real-time clock (RTC) acts like a “mechanical watch” that never loses power; it can persistently record time even when the device is turned off. … Read more
