1. Naming method of resistor model: The model of domestic resistors consists of four parts (not applicable to sensitive resistors). The first part: the main name, expressed in letters, indicates t...
The code for the 8*8 dot matrix, this is a two-color 8*8 dot matrix, it is written in two parts in sequence. First learn to light a light, and then learn to make it display the effect of flowing water...
The above are all 8-bit addressing, but the data in DSP is obviously wrong (for example, 0x03030101, should be 0x04030201), I don’t know why, I hope the experts passing by can answer, I will be very g...
The pj 342 package has a little deviation, that is, the two positioning holes below have deviations, which needs attention!!! There is a capacitor missing in the tuning potentiometer!!! The schematic ...
Reprinted from Qianjia.com BG7JWE I believe everyone is familiar with the current power supplies that cost a few yuan or ten or twenty yuan, right? Similarly, I have also disassembled quite a few. Tod...
Why use frequency domain?
On the one hand, when we first came into contact with learning circuits and signals, we were dealing with voltages and currents that were static relative to time. For example...

The integration of sensor technology and RFID has just started. As one of the world's major manufacturing and consumer countries, China should seize this opportunit...[Details]
PCI (Perip heral Component Interconnect) is an advanced high-performance 32/64-bit local bus that supports linear burst transmission and has a maximum data transmission rate of 132MB/s. At the same...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
As mobile phones have evolved from simple voice communication tools to multimedia devices that integrate communication, imaging, and gaming, application processors are replacing baseband chips as t...[Details]
In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]
When you hear the word digital TV, you may feel fresh and excited, but when it comes to what digital TV is and what it can bring us, you may still be confused. You must be very eager to understa...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
Preface
In the analog era, due to the unchanged specifications and relatively simple device connections, as well as users' low requirements for image quality, the relatively simple environment...[Details]
Some application designs have higher requirements on the speed at which the system's switching power supply can provide voltage output. Figure
