[table=98%] [tr][td][color=#444444][size=18px]The OP4277 op amp is used to amplify the output signal of the piezoresistive film. The two-stage reverse proportional operational amplifier is connected i...
Microcontrollers (MCUs), which are widely used in automotive electronics, have been developing at full speed and are now facing time and cost barriers. The main benefits of using MCUs have always been...
The SPI bus is configured as master mode, single-wire bidirectional transmission mode. Use the MOSI pin.There is no problem sending data. When receiving, I only need to receive one byte of data, but t...
I want to make a quadcopter to participate in next year's "Challenge Cup" academic competition. I don't know if it can be realized with a 51 single-chip microcomputer. In addition, I need to learn som...
Emergency hand-held lamps powered by 6V maintenance-free batteries are widely used in rural areas. The charger used is a transformer step-down and single diode half-wave rectifier, and the charging...[Details]
A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into one chip. In general, a c...[Details]
System design is a complex process. It is not enough to just use ICs. There are many details to consider. This article uses a high-fidelity music playback system as an example to introduce how to s...[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]

Whether it is a master or a slave, fieldbus has won unanimous praise in the field of PC-based automation. For more...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
Problems such as the depletion of natural resources, air pollution, traffic congestion, and rising fossil fuel prices have forced societies and individuals to seek alternative means of transportati...[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]
Motors, especially those with brushes, generate a lot of noise. This noise must be dealt with if the appliance is to meet the requirements of EMC standards. The means to solve EMC are nothing more ...[Details]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
In the "digital pressure measurement" experimental device of applied physics, the subject technical knowledge of analog circuits, digital circuits, sensors and single-chip microcomputers is used. In o...[Details]
LED is the abbreviation of the English word. Its main meanings are: LED = Light Emitting Diode, a solid-state semiconductor device that can convert electrical energy into visible light. It can dire...[Details]
