#8th LCSC Electronics Design Contest# Dot Matrix Reminder Water Dispenser

Overview

Note: * Required fields,
please fill them in during the registration phase ↓

* 1. Project Function Introduction

The DIY Water Reminder is a smart device based on the STC8H1K, designed to help people maintain good hydration habits. This device can remind users to drink water at set times to ensure they stay adequately hydrated, contributing to health and quality of life.

Timed Water Reminders: The DIY Water Reminder can be set to remind users at set times, such as once per hour. This helps users avoid forgetting to drink water due to being busy.
Display Screen: The device has a dot-matrix display screen that shows the current time, reminder schedule, and water level in the cup. Users can easily understand the information.
Sound Reminders: In addition to the dot-matrix display, the device is also equipped with a buzzer reminder function.
Customizable Reminders: Users can customize the reminder frequency and time according to their needs. This customization function allows the device to adapt to different people's lifestyles.

*2. Project attributes

have only been publicly disclosed on the LCSC EDA open-source platform; Original.

* 3. Open source license

GPL3.0.

Please fill in the details during the competition stage.

* 4. Hardware:
Use M3*10mm double through studs to connect the top and bottom plates. Note the soldering method between the DS1302 battery holder and the DS1302. Changing the time requires re-downloading the program. After changing the time, comment out the time-writing code and download again. Please use a passive buzzer (the sound is music - Two Tigers). If board assembly prevents board production, please delete the oval border layer in the middle of the PCB and cut it open yourself.

* 5. Software:

See the attachment for the specific source code. Open the source code in Keil and use STC-ISP to download the program to the STC8H1K chip.

* 6. BOM list.

* 7. Competition logo verification.

* 8. Demo your project and record a video to upload.

Doubts about the 8080 bus
[i=s]This post was last edited by flashtt on 2016-11-2 20:03[/i] I have never studied the timing diagram carefully, so I don't understand this aspect. Taking the 8080 parallel bus as an example, I hop
Can you give me a timing constraint?
This timing is always difficult to constrain. I have constrained both the rising and falling edges, but there is still a problem? How can I constrain this better in DC? This is an output signal in 805

I would like to ask the experts in the forum, is there anyone who can do this? The design of "short-distance ASK/FSK/GFSK wireless modulator" requires a frequency of more than 400MHZ. The chip should

Can anyone provide me a bootload code for s3c2440 booting from Norflash? There are so many bootload codes on the Internet, but most of them are booting from Nandflash! It would be best if it is compil
After using it many times, this one is the best. How do you use it?
As shown in the figure, long-term practice has proved that this model is the easiest to understand, communicate, and implement. Can you give an example so that others can see what you have done?
