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 ...
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...

For example, chips such as DAC0832 and PDIUSBD12 are all parallel transmission, and the chips have WR and RD pins. When using this chip, you may connect WR and RD to the ordinary IO port of 51...[Details]
When the chip is powered on and reset, bit6 and bit5 of F4 are random, and non-powered reset keeps the original state unchanged. The following example writes data to the 30H and 50H registers of B...[Details]
