After I bought it, I couldn't connect to the Bluetooth no matter what! It felt like pressing the AB button was always the same, no pattern would appear :Cry: Later I burned in another program, and the...
We have been negotiating since May and now the customer called to say he wants to place an order. When I hung up the phone with the customer, I felt very happy. I felt that after following this order ...
For example, if the sampling rate of the MCU ADC is 200KSPS, is it equal to 200KHZ? Does it mean 200K samples per second? If the crystal oscillator is 11.0592MZ, how to determine whether the clock fre...
I was really envious of Ma Ge’s multi-function debugging tool, so I also made a high-speed USB hub and supported an xlink, and used stm32 to realize USB to serial TTL/serial 232/serial 485 (through ju...
As the title says, if I click on the clock in the tray to change the time, what registry entry will be modified accordingly? Please give me some advice!...
[p=null, 2, left]This test simulates the repetitive damped oscillatory waves that appear in the power cables, control cables and signal cables installed in high-voltage and medium-voltage substations,...

Safety is the top priority in the production process, especially for dangerous operations. When the high-voltage line is shut down for maintenance, it is necessary to follow the regulations of powe...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
This article first briefly introduces the working principles of current mode and voltage mode and their respective advantages and disadvantages; then discusses the ideal voltage mode using output c...[Details]
Designers of handheld products such as cell phones, digital cameras, MP3 players and personal digital assistants (PDAs) are continually challenged to deliver more functionality in a smaller form...[Details]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pres...[Details]
Introduction
The home ECG and blood pressure monitoring system consists of a data acquisition and recording device and a host computer electronic medical record management system. Therefor...[Details]
Multiple Input and Multiple Output (MIMO) technology is arguably the next most important development in wireless communication technology since the advent of digital communications. Many new wir...[Details]
