Cortex_m3_stm32 Embedded Learning Note (14): RTC Real-time clock (seconds interrupt)

the STM32 real-time Clock (RTC) is a stand-alone timer. The RTC module of the STM32 has a set of continuously counted counters, which, under the corresponding software configuration, provides the function of the clock calendar. Modifying the value of a counter can reset the time and date before the system. Since the

Key points of the S3C2410 real-time clock Module

Author: Yang Shuo,Hua Qing vision embedded college lecturer. 1. Overview RTC functions: Generally, RTC is used to provide reliable system time, including information such as year, month, day, hour, minute, and second.RTC works properly when the system is shut down, because it is powered by a backup battery.The peripheral of RTC does not require too many auxiliary circuits. Typically, you only need a high-precision 32.768khz crystal oscillator and capa

Tomato working method (tomato clock time management)

effectively manage or use time? First, we need to concentrate on solving a certain problem. Second, we need to have a plan (What should we do? Where can this problem be solved? How long? Emergency level ?) The basic process of the tomato working method consists of five stages: Planning: determine the activity of the day at the beginning of the day Tracking: record how many tomato clocks you have completed in a day, and which ones are within your est

RTC Real-Time clock-backup area bkp--principle explanation

RTC (Real Time clock): Realtime clockBCD code: 4-bit 2 binary to represent the decimal form within 10.RTC Clock Source: LSE (32.768KHZ), HSE_RTC, LSI. After a precise calibration (RTC_CALR). The 7-bit prescaler is then divided (rtc_prer, default 127+1=128) to produce a ck_apre () clock. Again after a rough calibration

Setting up a time server with "network precise clock"
