ZYNQ-FPGA-RTC (real-time display clock)
1. PCF8563 introduction The data generation of the real-time clock is completed through the PCF8563 module. PCF8563 has alarm function, timer function, time Clock output function and interrupt output function. Memory addresses 00H and 01H are used as control registers and status registers (CONTROL_STATUS); memory addresses 02H~08H are used as TIME timers (seconds~year timers); addresses […]
RTC real-time clock experiment
RTC Clock Introduction The real-time clock (RTC) of the STM32F103 is an independent timer. The RTC module of STM32 has a set of continuous counting counters, which can provide a clock calendar function under the corresponding software configuration. Modifying the counter value can reset the system’s current time and date. The RTC module and clock […]

CQU digital logic experiment 2 – verilog digital clock source code and constraint files
Some ideas are collected from various materials, and there are also some optimizations. I may modify the code in the future, such as using modular arithmetic for optimization. Hours are LED lights The source files are as follows: `timescale 1ns / 1ps // //Company: // Engineer: // // Create Date: 2023/10/24 10:57:00 // Design Name: […]
RTC — real-time clock
1. Introduction to RTC Real Time Clock (RTC) is essentially a counter with a counting frequency of seconds and is specially used to record time. Ordinary timers cannot be used as clocks because they cannot run when powered off. RTC features: Can provide time (number of seconds); Can run after the MCU is powered off; […]
