Ornamental fish tank controller

The ornamental fish tank controller is studied, developed and verified based on the Arm® Cortex®-M23 core GD32E231C-START evaluation board provided by GigaDevice for this competition. Finally, the GD32E231C8T6 microcontroller chip donated by GigaDevice was used to realize the status control of the fish tank circulating water pump, the three-stage brightness control of the LED lighting, and the granular bait feeding control using the 315MHz remote control receiving and transmitting device and other related peripheral equipment. As well as an ornamental fish tank controller with functions such as water temperature collection and digital tube display.

Outdoor environment detection device based on the Internet of Things (STM32, APP, WIFI).zip

This article develops and implements a WiFi module based on STM32 on an embedded development platform. Combined with the above new concepts of the Internet of Things, it enables users to monitor the environment in real time through the network. This system enables users to grasp and control the situation they want to know in real time. Home information (temperature and humidity information, light information, PM2.5) is obtained through various sensors, and users can control this information on the Android interface.

Car emergency braking flashing device

In traffic accidents, rear-end collisions occur frequently due to sudden braking of the vehicle in front. Rear-end collisions are usually caused by failure to maintain a sufficient safe distance and the brakes cannot stop the vehicle. The time from when you discover an emergency ahead to when you apply the brakes is called reaction time. The length of reaction time directly affects the length of the braking distance. Especially when driving at high speed, a serious traffic accident will occur within one second. The long reaction time does not mean that the driver is slow to react, but that he does not know whether the car in front is applying the brake lightly or hard. When he finds out, two seconds have passed, and it is very likely that he will not be able to brake. If the vehicle in front The brake lights with flashing function are different. When you see the brake lights flashing, you must be stepping on the brakes harder. At this time, you should also step on the brakes harder, and the reaction time will be shortened. Therefore, in addition to letting the car behind you know whether to apply the brake lightly or hard, the flashing brake light is also particularly eye-catching and can remind the car behind you in time.

gpdi-serdes: GPDI using serdes

SYZYGY is an FPGA extension standard for medium to high speed interfaces. This design splits the video output to a regular digital display and also supports input from the digital display. It connects to the SERDES via a SYZYGY-TXR connector. Would love to be able to test the 5Gbps output of high resolution GPDI.
