desktop clock

Overview

This project is for the Desktop Clock Competition of the Radio Association of the School of Physics and Electronic Engineering of Chongqing Normal University. The organizer modified the reference case provided by the non-professional group students with weak foundation,
optimized the original schematic diagram, and selected and redesigned the devices. The PCB layout was carried out and a small part of the code was modified.
Main components
TM1650, DS3231, STC15W408AS
Main functions
(1) Accurate travel time, the error does not exceed 1 second in one hour (no more than 1min in 72 hours)
(2) The time function can be set manually. (3) The year, month, day, week, hour, minute and second can be displayed, and the display can be updated in real time by the second. (4) The feature of continuing to run time when power is turned off is designed to realize the function of not stopping the time when power is turned off and still displaying the time accurately when power is turned on again. (5) Setting and turning off the alarm clock
(6) Able to display real-time temperature
