Does anyone have a mature DC brushless motor drive solution using a 51 single-chip microcomputer? The source code and circuit diagram of the drive must be provided for reference.
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
