430 microcontrollers generally have an internal information area to save some data that requires EEPROM to save. I did not receive relevant information in the forum, so I borrowed the information on t...
In recent years, the market for mobile/portable devices such as smartphones and laptops has continued to grow rapidly. While these products continue to integrate more new features to enhance the ...[Details]
1. Introduction
Light control circuit plays a vital role in urban street lamps or corridor lighting. With light control circuit, the lights can be automatically turned on and off according to ...[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]

Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[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]
Leakage current is generated by parasitic resistance paths between the measurement circuit and a nearby voltage source. This current can significantly reduce the accuracy of low current measurement...[Details]
Don’t just look at the power when choosing a power supply
We know that a power supply with a low rated power can hardly meet the power supply needs of the system, which may cause frequent free...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
Stepper motors, also called steppers, use the principles of electromagnetism to convert electrical energy into mechanical energy and have been used since the 1920s. With the increasing popularity o...[Details]
In the past 20 years, although the inverters that use power transistors (GTR) as inverter power devices, 8-bit microprocessors as control cores, and realize asynchronous motor speed regulation acco...[Details]
