Currently, the SOPC based on OR1200 uses too many peripheral devices (such as Flash, SDRAM), which limits its application in small and medium-sized embedded systems. I have an idea, but I don’t know i...
I want to realize a function, that is, using a single-chip microcomputer (such as: AVR), a flash memory chip (large capacity, similar to the kind on a USB flash drive), I want the single-chip microcom...
introduction
In the discharge process of tokamak plasma physics, the study of rupture and sawtooth is of great significance. Rupture and sawtooth exist in most tokamaks. Rupture is a notew...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[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]
Abstract: With the development and construction of BeiDou II system, China will shift from the situation dominated by GPS to the situation dominated by BeiDou II global navigation system independen...[Details]

At present, a large number of cooling tower fans, speed fans and special fans are in use in petroleum, chemical, pharmaceutical, metallurgical and other enterprises. Some fans have no monitoring in...[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]
1. Tips for charging UPS for the first time
After purchasing a new UPS, plug the UPS into the 220V mains power grid and charge it for at least 12 hours to ensure that the battery is fully char...[Details]
The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]
Direct digital frequency synthesis (DDS) has fast frequency switching and modulation capabilities and is widely used. However, when low power consumption and low cost are the main considerations, D...[Details]
TMC428 is a stepper motor motion controller from TRINAMIC. It can reduce the workload of motor control software design and development costs. The 3-axis stepper motor drive control system based on ...[Details]
In some motion control systems with simple control or low cost requirements, stepper motors are often used as actuators. The biggest advantage of stepper motors in such applications is that they ca...[Details]
