The platform can be synchronized for the first time when it is powered on, but it will be disconnected after a period of time, and it will not be synchronized afterwards. My colleague said it is a pro...
Core device: TPA2010 Many PWM (pulse width modulation) applications, such as Class D audio amplifiers, require symmetrical drive circuits. The CMOS pair in Figure 1 consists of complementary N-channel...
I recently worked on a mobile phone project, and the charger chip used was SMB Qualcomm. When the battery was fully charged, the charger was plugged in, and the test would suddenly fail all night! I h...
The installed OS is WINCE6.0+SP2, and the updated package is installed. When compiling OS with built-in BSP under WINCE6.0, there is always a compilation error, and the build.log file outputs: EDITBIN...
Repair diagram reading refers to the analysis of circuit diagrams during the repair process. This reading is very different from the reading of diagrams when learning the working principle of circuits...
1. Introduction
RFID (radio frequency identification) is a non-contact automatic identification technology that emerged in the 1990s. It uses the characteristics of radio frequency signal prop...[Details]
Do you often have to add brake fluid to your car's brakes? The fact that you need to pump out the brake fluid to make sure there is no gas in the brake fluid line may not be done by the car owner h...[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]
For a long time, due to the limitation of hardware conditions, the display devices of traditional small handheld devices such as PDA are usually monochrome LCD, and the user interface is very simpl...[Details]
Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[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]

1. Introduction
Testing the temperature of steel billets before rolling is an important measure to ensure the quality of steel. Traditional manual testing is difficult to ensure product qu...[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]
General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[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 concept of state machine
State machine is an important concept in software programming. More important than this concept is its flexible application. In a clear and efficient program, ther...[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]
