FET-Pro430 Programmer:
How can I make Serialization work?
Look carefully, the sequence setting of the programmer is dark, how to light it up?
Do I need to register to use it?...
Now we need to add SRAM to the BBB to store some important data. We want to connect SRAM to GPMC. The datasheet says it can be connected, but when I look at the source code of u-boot, I don't see any ...
Common emitter circuit, when the V1 power supply (5V) is not enough to provide the transistor collector, Ic
"When V1 is 5V, how do you calculate the current at the b pole?" Of course you can calculate...
ARM was praised for its superior performance when it first appeared. Is ARM really better than 51? But apart from the fact that its price is much higher than 51, its superior performance is not hinder...
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]
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[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]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]

Smart lighting control systems provide high controllability for various buildings and further enhance the level of green energy. They are the core products of energy conservation and digital techn...[Details]
With the continuous consumption of earth's energy and the scarcity of resources, the harm of greenhouse effect to human beings, and the serious pollution of the atmosphere to the earth, the intern...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
The traditional display screen using 51 single-chip microcomputer to control LED dot matrix has relatively simple functions. If it is to achieve diversified functions, it often takes a lot of time ...[Details]
FPGAs are used in 81% of electronic systems, including many commercial and defense products, and most FPGAs use BGA packaging. The BGA packaging is characterized by small solder balls and small sol...[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]
Abstract: Aiming at the needs of coal-rock acoustic emission signal monitoring system, a data acquisition circuit with 24-bit resolution and 16-channel synchronous data acquisition function is desi...[Details]
