Disassemble the memory stick into particles and then put it back
sequence:
I have always had a special liking for memory sticks. The first host I equipped in 2014 was equipped with Kingston DDR3 1600M...
Let me ask a simple question. I use 52 to control 220V AC power through 74hc14/12V relay. Because two AC power lines are controlled at the same time, that is, two sets of relays, when I close one line...
Use 74LS194 (shift register), 74LS138 (3-8 decoder), 74LS20 (NAND gate), 74LS74 (D flip-flop). Design an accumulator. How should I design it? I can't figure it out no matter how hard I try. Especially...
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]
China's new energy vehicles are in a transition period from research and development to real industrial development. In 2012, with the intensive launch of new energy vehicle policy planning, the de...[Details]
1. Principle of displacement angle sensor
The angle sensor is used to detect angles. It has a hole in its body that fits the LEGO axle. When connected to the RCX, the angle sensor counts once ...[Details]
A multi-point temperature control heating control system was designed using the SST89E564RC single-chip microcomputer and a new temperature measuring device. The heating system can be controlled in...[Details]

This paper designs a 16x16LED Chinese character display bar based on single-chip dynamic scanning control, briefly analyzes the principle of Chinese character display, and studies how the LED displ...[Details]
Problems such as the depletion of natural resources, air pollution, traffic congestion, and rising fossil fuel prices have forced societies and individuals to seek alternative means of transportati...[Details]
Motors, especially those with brushes, generate a lot of noise. This noise must be dealt with if the appliance is to meet the requirements of EMC standards. The means to solve EMC are nothing more ...[Details]
Corelink Semiconductor has launched the CL1100-based 5-7W E27 LED lighting driver system solution DB2. This driver module meets the requirements of small size (L×W×H=5.1cm×2.1cm×1.8cm), low standby...[Details]
LED lighting: Basic circuit design can be completed in as little as one day
Semiconductor manufacturers are also getting involved in the LED lighting business. The power circuit of LED req...[Details]
Liquid crystal display (LCD) panels have a wide range of applications, from small portable electronic devices to large fixed devices, including digital cameras, laptops, personal data assistants, d...[Details]
The ARINC429 bus is one of the most commonly used communication buses between various subsystems of avionics. As the "skeleton" of modern avionics systems, once the bus system or the attached airbo...[Details]
When the so-called "copycat phones" that flood the domestic mobile phone market move towards large screens, stereo amplifiers, touch controls, and even GPS navigation and mobile TV, the homogeneity...[Details]
LED is the abbreviation of the English word. Its main meanings are: LED = Light Emitting Diode, a solid-state semiconductor device that can convert electrical energy into visible light. It can dire...[Details]
The future energy storage hotspot is not coal or iron ore, but lithium. This lightest metal in nature may be the heaviest resource in the future energy landscape. China launched an ambitious electr...[Details]
