I have an AT switching power supply that needs to be repaired. The solution is TL494+LM339. The fault phenomenon is: the positive and negative 12V output is only more than 8V, and 5V is normal. I init...
The serial port and keyboard have two interrupts. The keyboard triggers the serial port to send data, and the display screen receives data. The two do not interfere with each other. But now when a key...
I use ULINK 2 to debug my own board (the connected JTAG signal lines are: JTAG_TDI, JTAG_TDO, JTAG_TCK, JTAG_TMS, JTAG_TRST connected signals). I started to think that the problem was that nreset was ...
[size=4] Media reports in recent years have let us know that China's integrated circuits are still far from the world's advanced level. But here I will first talk about an industry that is rarely repo...
The demos-sprinkle part of the CC3200 LaunchPad Out of Box routine implements the function of submitting data to the HTTP server of CC3200 through a POST request. [/size][/font][/color][/align][align=...
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]
This article discusses how to wake up a touch-sensitive device such as a tablet without touching the device, using basic gesture recognition and novel proximity sensors. The article discusses the p...[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]
This paper establishes a fuel cell engine test platform based on the NI integrated hardware and software environment. This platform can realize the test and control of fuel cell engines and their a...[Details]
The data collector of the automatic weather station is generally designed based on a single-chip microcomputer or a PC/104 bus controller. It has the characteristics of good compatibility with PC, low...[Details]
1. Background:

In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[Details]
The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
The above is to use MB1404 as a stereo composite signal transmitter. You can use the internal high-frequency amplifier and oscillator or not! According to my experience, I still recommend beginners...[Details]
Cars equipped with xenon headlights are already common on the road. Whether they are standard equipment on high-end cars or embellishments on modified cars, xenon lamps are gradually becoming a sym...[Details]
Car lights, whether headlights, fog lights or tail lights, play an important role in driving safety. However, the material of the car lights determines that the probability of damage in a collision...[Details]
The emergence and development of street lamps are inseparable from the prosperity and progress of cities, which makes street lamps useful. Conversely, street lamps also make the night of the city n...[Details]
