Design of an Scalable Infrared Remote Control Device
This paper describes the design of an expandable infrared remote control device.This design is based on the HXD019-SOP8 intelligent infrared remote control chip,which uses the l2C protocol to package and transmit remote control codes,and achieves multi device control through a 38kHz carrier wave.The design considers stability,power consumption,compatibility,and anti-interference,and adopts three-level filtering,I2C isolators,etc.to enhance system reliability.
