Electronic clock design based on STC8H1K08

This paper presents the design of an electronic clock system based on the STC8H1K08 microcontroller. The design includes clock display, timekeeping, and chime functions.

1. Engineering Principle: The electronic clock utilizes an STC8H1K08 microcontroller to control various display devices (such as LED digital tubes or LCD screens). It uses internal timer and counter modules for precise timing and external input devices (such as buttons) to set the time and alarm functions. Through proper programming and peripheral connections, it achieves time display, timing, and chime functions.
2. Function: The electronic clock's function is to accurately display time, provide timing and chime functions, and offer convenient time information to users. 3.
Operating Conditions:



Power Supply: The STC8H1K08 operates within a voltage range of 2.4V to 5.5V; therefore, the electronic clock's operating conditions must meet this voltage range.
Ambient Temperature: The STC8H1K08 typically operates within a temperature range of -40°C to 85°C; therefore, the electronic clock's operating environment should be within this temperature range.

Wideband small loop antenna

PCB traces act as coils, forming a small loop antenna.

The PCB traces act as coils, with an inductance of approximately 440uH calculated in simulations, equivalent to a ferrite rod antenna. However, due to the low self-resonant frequency, it is estimated that above the self-resonant frequency, it will function as an electric field antenna, also providing some gain.

Intelligent vehicle TC264 motherboard V1.2

This motherboard was specially prepared for the 2023 Intelligent Vehicle Extreme Off-Road Group. It was designed in my second year of university and has some minor flaws, but they do not affect its use. It is modeled after the official motherboard and is intended as a reference for other groups in the next Intelligent Vehicle competition.

This motherboard was specially designed for the 2023 Intelligent Vehicle Extreme Off-Road Group. It was designed during my sophomore year and has some minor flaws, but these do not affect its use. The design is modeled after the official motherboard and is provided for reference by other groups in the next Intelligent Vehicle competition. Major components can be directly imported and ordered from the LCSC online store. I recommend buying a resistor and capacitor kit; it will save you a lot of trouble.

EDP ​​screen adapter board for NanoPC-T4

Convert the NanoPC-T4's custom EDP interface to a universal 30-pin EDP.

 
The project has been tested and is working properly.
 
The LCSC prototype is 1.2mm thick, using a JLCSC 7628 structure. The minimum line spacing is 6mil.
 
**Note:** Pay close attention to the orientation of the EDP ribbon cables at both ends!!!

Don't ask me how I know this…
 
The specific type of ribbon cable used depends on your screen; I used two correctly aligned ribbon cables this time.
 
 
The resistors soldered on the PCB are pull-up resistors for the EDP AUX channel. During debugging, because the NanoPC-T4 board had them but they weren't installed, I added them;
 
in practice, they weren't needed. There was a very frustrating experience when adapting the device tree. The FriendlyARM 4.19 kernel source code had significant compatibility issues with the T4, and there was absolutely no software support. As a beginner, I struggled for a very long time. Either the screen backlight wasn't working and the panel displayed normally, or the backlight was working but the panel wasn't. I especially want to complain about FriendlyARM's software support. I applied to four support groups and only got into two after a month, and those groups were completely inactive with no replies or daily chat.
 
Finally, I discovered, to my dismay, that FriendlyARM automatically turns off the backlight after recognizing the panel, requiring manual activation! No matter how absurd this is, it actually works. Finally, I wrote a shell script and placed it in the system startup directory to "manually" turn on the backlight at startup...
 
Finally, the screen lit up and I got to the desktop. The white bars were because the screen was defective; after replacing the screen, it returned to normal.
 
 
Finally, here's a picture of Genshin Impact using an adapter (doge).
