Under CE6, this project was originally used on AT9261, and later changed the BSP and used it on AT9263. The project itself did not add or subtract any components, only the BSP was changed. The problem...
Everyone probably has moments of being inspired, perhaps by an article, a book, a sentence, a situation, or even by reflection after a setback. But whether this inspiration leads to a change in one's ...
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer

Water resources are the basic conditions for human survival and the lifeline of economic development. The reality shows that due to the global shortage of water resources and th...[Details]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[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]
System Overview
The system consists of a signal preprocessing circuit, a single-chip computer AT89C2051, a systematic LED display module, a serial port data storage circuit and system software...[Details]
Introduction
In industrial control, speed measurement is often required. Generally, a contact tachometer is used. This tachometer must be placed against the center of the shaft to measure. It...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
Analysis of the three core aspects of digital TV transmission standards
According to the differences in regionality, transmission method and modulation method, the transmission method needs to...[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]
One in five car failures are caused by batteries, a problem that will become more serious in the coming years as electric-by-wire, start/stop engine management and hybrid (electric/gas) vehicles be...[Details]
DCDC means DC to DC (conversion of different DC power values). Anything that meets this definition can be called a DCDC converter. Specifically, it means converting the input DC into AC through a s...[Details]
