Audio interfaces are increasingly becoming a desired feature of embedded designs. At the same time, users of embedded systems are demanding higher and higher audio quality. For developers, this presen...
For embedded software, the smaller the code size, the better. Compressing the code to fit into a memory subsystem that is constrained by cost or space has become an important issue in embedded system ...
Finally, it's not the small LCD of 5110 anymore. I found the dusty 12864. This one still has fonts. Haha, serial mode, only 3 wires are needed. If you ignore the chip select, two wires are enough~
The...
First, I'll post the program I used, which I downloaded from the Internet. I have passed the hardware test and there is absolutely no problem [code] #define WRITE_SECOND 0x80 #define WRITE_MINUTE 0x82...
I made a board based on the 2410 development board of Broadcom, but the network chip used is different, and Broadcom only provides Eboot. How can I download the kernel through USB? It seems that it co...
I want to control the on and off of a constant current source. The current is about tens of milliamperes. Can I use an analog switch to control it? If yes, can you recommend a few? One with 16 channel...
With the promotion of the construction of intelligent communities in the country, anti-theft systems have become essential equipment for intelligent communities. Especially in recent years, the urg...[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]
This paper designs a dot matrix LED text display screen that is easy to update, expandable, and low-cost. The way to reduce costs is
① Use the Bluetooth data transmission function of mobile ph...[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]
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]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
PV inverter manufacturer SMA has launched its first DC arc fault circuit interrupter (AFCI) PV inverter and has received UL certification.
The new SunnyBoy AFCI inverter models include 3000-US...[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]
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]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
Spatial Division Multiplexing (SDM) MIMO processing can significantly improve spectrum efficiency and thus greatly increase the capacity of wireless communication systems. Spatial Division Multip...[Details]
LED light sources have many environmental advantages, but early products still have certain technical bottlenecks in heat dissipation and high brightness design that cannot be broken through....[Details]
This article discusses the six design steps of LED lighting system design in detail: (1) determine the lighting requirements; (2) determine the design goals and estimate the optics; (3) the efficie...[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]
In recent years, with the increasing maturity of LED technology, LED light sources have been increasingly widely used due to their advantages of using low-voltage power supply, low energy consumpti...[Details]
