Since wireless networks use radio waves to transmit data signals and adopt radio frequency (RF) technology to send and receive data through the air, the role of antennas is extremely important. With t...
1. If the MCU has a serial port peripheral, adding a level conversion chip, such as MAX232, SP3485, will become the RS232 and RS485 interface.
2. RS485 uses differential signal negative logic, +2~+6V ...
The oscilloscope signal acquisition mode is used to control how to generate waveforms from sampling points. The commonly used waveform capture modes of Dingyang oscilloscopes are normal mode and peak ...
I believe that many of my friends have this question when studying electricity or using a wiring harness tester: how does alternating current become direct current?
First, let's understand the basic c...
