Recently I have been dealing with domestic substitution plans. Although the plans are there, the domestic chip production capacity is insufficient and there is no supply.
So I have always had a questi
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
