The 2012 TI Cup has already ended. I still have some photos taken during the training on my phone, mainly the LaunchPad assignments that students were assigned to complete....
I would like to ask how to turn off the automatic layer selection function for routing... When I draw a 4-layer board, I select Signal Layer 1 or Signal Layer 2 for routing, but as soon as I click on ...
Today I saw a simple constant current charging circuit. I can only understand the voltage reduction, rectification and filtering parts. The other functions seem
I don't understand, please give me some...

main() { EA=1; EX0=1; IT0=0; while(1) P1=0xff; } void exter0() interrupt 0 { P1=0; } For this simple external interrupt, I directly connected INT0 to ground with a switch. Why does the LED di...
The chip I use is 149, parallel port simulation. It can download when the chip is just soldered, but it can't download normally after a while. It always prompts that the chip cannot be found. I have c...
I received the MSP-EXP430FR5739 development board today, and found that it does not have a traditional JTAG socket. I have a development board, but no CD, and I don't know how to download the program ...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]

Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[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 rapid development of urban economy, elevators are increasingly used as a vertical transportation tool. However, elevator fault detection and maintenance, especially the role of elevator remot...[Details]
With the development and widespread application of computer technology, especially in the field of industrial control, computer communication is particularly important. Although serial communication g...[Details]
LED is the abbreviation of light emitting diode, which is an electric light source made of semiconductor technology. The core part of LED is a chip composed of P-type semiconductor and N-type semi...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
It is well known to automotive suppliers that automakers are demanding more from their supply base. For connector suppliers, this means stricter requirements for product performance, stability and ...[Details]
The era of mobile access to the Internet has arrived, and it will rapidly change the business and infrastructure needs of mobile operators under a whole new trend of requirements. We need 4G LTE to...[Details]
LED guardrail lights use fluorescent tubes or LEDs as light sources and continuous guardrails as carriers to form an approximately linear guardrail light strip. This article mainly introduces...[Details]
Only a small number of LED manufacturers can produce high-quality LEDs. For applications that are only used for simple indication, low-quality LEDs are sufficient. However, high-quality LEDs must...[Details]
