I recently debugged FPGA to write data to RAM. The data bus of RAM is 72 bits and the address bus is 20 bits. Since the same data needs to be written to 6 RAMs, the design is made like this: the exter...
Let’s start with a simple question: How fast can the GPIO flip speed of STM32 (for example, used to simulate timing) be? Write a piece of code to test: [code]void test(void) { for(;;) { GPIOA->ODR = (...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]

This design was made for participating in an electronic design competition. It effectively solved the problem of the operation and control of an electric car on a seesaw. The s...[Details]
Do you often have to add brake fluid to your car's brakes? The fact that you need to pump out the brake fluid to make sure there is no gas in the brake fluid line may not be done by the car owner h...[Details]
With the advent of increasingly powerful processors, image sensors, memory, and other semiconductor devices, as well as the algorithms that enable them, computer vision can be implemented in a wide...[Details]
For a long time, due to the limitation of hardware conditions, the display devices of traditional small handheld devices such as PDA are usually monochrome LCD, and the user interface is very simpl...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]

In the past 30 years, major electronic component manufacturers in the world have launched their own unique single-chip...[Details]
As people's requirements for safety and comfort in the process of driving cars continue to increase, automotive radars are widely used in the car's adaptive cruise system, collision avoidance syste...[Details]
This article will introduce a design method for a distributed control system used in a tracking car, which can perform distributed control of motor modules, sensor modules, and lighting control mod...[Details]
Abstract: In order to realize wireless automatic alarm and monitoring of major safety places, based on the basic principle of pyroelectric infrared sensing, a detector for receiving infrared radia...[Details]
Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
Almost everyone in a student dormitory has a bedside lamp. But if you want to read for a while after turning off the lights and don't want to disturb your roommates' sleep, you may need a reading l...[Details]
The fluorescent lamps and energy-saving lamps we commonly use now have greatly improved luminous efficiency compared with the earlier ordinary incandescent lamps and have been widely used. With the...[Details]
