Rookie, because, I'm just in the day after tomorrow want to hand in the project, I made a monitoring software with VC, but I don't know how to use MSCOOM interface rs485 serial port control energy-saving lamps, which a great god willing to pick up this job and I QQ420719297, 100 yuan for the hard work the e-currency payment, I know it is very simple for you, but the rookie is really a headache for me, time is also very nervous, in relation to my confirmation, so trouble see contact me, trouble you great god

Old rookie rolled over, vc go vc and MFC version for help

CodePudding user response:

MSCOOM serial port to send the corresponding control commands and to have hardware description

CodePudding user response:

RS485 serial port protocol only transmission voltage, impedance and RS232, programming method and the RS232 serial port programming

CodePudding user response:

The communication protocol it is ok to want to come,

CodePudding user response:

What lit LED lights to the agreement?
Pull up or pull the bottom level directly, through a relay is done,

CodePudding user response:

Rs485 communication protocol, just only a + - two signal lines, high power leds to current is big, 485 signal lines is not bright,

The energy-saving light of rs485 interface, that is similar to the single chip microcomputer CPU energy-saving lamps, provide a 485 interface, energy-saving lamps will explain instructions, to run,

If you don't have energy-saving lamps and communication of related instructions, you are not by 485 lighting energy-saving lamps,
If you want to design an energy-saving lamps, can control through the COM, is another matter,
