According to the timing requirements, we set the VM/VDEN signal as the ENAB signal of the LCD, and the VCLK signal as the NCLK signal of the LCD. To obtain the appropriate VM and VCLK waveforms, we mu...
How to adjust the timing when porting the LCD display program of 51 to AVR? The logic should be fine and it can run on 51. It must be that the timing is wrong, so the data cannot be written....
The Mobile Industry Processor Interface (MIPI) Alliance is an organization responsible for promoting the standardization of software and hardware in mobile devices. It has released the D-PHY specif...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]

With the advocacy and implementation of the government's Safe City Plan, the security market has increasingly higher requirements for the clarity of surveillance images. Imagine that after a case o...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
The emergence and development of street lamps are inseparable from the prosperity and progress of cities, which makes street lamps useful. Conversely, street lamps also make the night of the city n...[Details]
The overall operating performance of an electric car depends first on its battery system and motor drive system. The drive system of an electric car is generally composed of three main parts: a con...[Details]
