The chip gets hot after powering on. The bootloader can be downloaded via JTAG, but it doesn't run! No information is printed out on the serial port, and the LED light is not on! What is the reason? I...
Abstract: A dual-channel 10A output switching regulated power supply based on the L4970APWM chip is first introduced. The main performance characteristics, packaging and parameter selection of main pe...
I recently wrote a small serial communication program. When doing software simulation, the data can be stored in the transmit register, but when connecting the chip for online simulation, the data can...
The U.S. Food and Drug Administration (FDA) points out that home health care is the fastest growing area in the medical device industry. Driven by the increase in average life expectancy, the increasi...[Details]
1 Overview
Drugs are like a "double-edged sword". They can treat diseases but can also cause serious adverse consequences. The dual nature of drugs depends on whether they are used rationally....[Details]
Ultrasound systems are among the most sophisticated and complex signal processing instruments in widespread use today. Like any complex instrument, there are many trade-offs to be made in implement...[Details]
The role of digital-to-analog converters
Real-world analog signals, such as temperature, pressure, sound, or images, are constantly being converted into digital form that is easier to store, p...[Details]
