describe:book485Infrared remote control is mainly used in smart home,Equipment control in various scenarios of household appliances and other equipment。
The first two working modes of this infrared:NECCommand mode(Short code:Television,TV box,Projector, etc),Duty cycle time mode(Long code:It is generally used for non-standard productsNECCommand device,Such as air conditioning, etc)
485 turn infrared remote control learning type
Data format of duty cycle mode:Every two bytes make oneU16Format of infrared level time,0x8000:Highest position = 1,It means sending38KCarrier time,0x7FFF:Highest position = 0,Send no38KCarrier time。
usage method:1、You can press the corresponding button on the infrared head through the remote control,The upper computer or serial port tool records the time data string of the button,When reusing,Pass the data string through theUSBTurn infrared to send out to control electrical equipment。
Time precision of learning infrared command:<10us。
485Communication parameters of serial port:Baud rate(9600),No check,8Data bits,1Stop bits
Communication distance:0-8m.
indicator light:Power indicator,Data sending prompt light,Data receiving indicator
Modulation and demodulation carrier frequency:38KHz。
