I would like to ask, when sampling a square wave signal (generated by a signal generator), the signal period sampled by AD is correct, but the time of the rising edge sampled is different from the ris...
I would like to share with you an MP3 decoding circuit board module that I have made, including the circuit board, schematic diagram, and driver program.
The main control chip is VS1003B
Welcome to do...
Hello everyone: I used to work on 51 and PIC microcontrollers, and now I want to do embedded system development. I would like to ask you: What embedded development software are commonly used? Which is...
Why can the maximum output voltage of UA741 only reach 8V? When my input voltage is a sine wave with an amplitude of 2 and a frequency of 1000, the output voltage is normal and the amplitude is 4V. Wh...
Project Overview
The micro urine analyzer we designed can detect ten parameters of urine, including white blood cells, nitrite, urobilinogen, protein, pH value, occult blood, specific g...[Details]
Preface
Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[Details]
Maximize instrument utilization and reduce
test times
Increasing the throughput of automated test systems can improve efficiency. Using off-the-shelf tools (COTS) such as multicore proc...[Details]
With the rapid development of digital technology, various digital display screens have emerged, including LED, LCD, DLP, etc. There are various control systems for various digital large screens, in...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
With the rapid development of computer technology, embedded image systems are widely used in office equipment, manufacturing and process design, medical, monitoring, sanitary equipment, transportat...[Details]
Over the past 15 to 20 years, automotive power MOSFETs have evolved from an initial technical topic to a thriving commercial sector. Power MOSFETs were chosen because they can withstand transient ...[Details]
In view of the problems in the actual FPGA development process, such as difficulty in locating faults, long compilation time after repeated code modification, and inability to confirm fault solutio...[Details]
Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[Details]
introduction
Controller Area Network (CAN) is a bus standard proposed by Bosch of Germany to solve the information communication between automotive electronic control units. With its excel...[Details]
At present, the IEEE802.11 wireless LAN standard is widely used in voice communication, wireless office and other fields, but it is still mainly limited to wireless communication on general platfor...[Details]
Some application designs have higher requirements on the speed at which the system's switching power supply can provide voltage output. Figure
