Addressable speaker system 1 wire long distance PWM like communication
Hello Folks,
I am working on an addressable speaker system project on which some 25 speakers are connected, each with a PIC MCU inside and want to select one at a time. CAT6(8 wires) cables are connected. two pair for power 24VDC and 1 wire for communication. Maximum length around some 200mtrs. I am planning to send a unique PWM signal to select a specific speaker from master MCU. The PIC MCU inside, receive PWM and detect duty cycle, and turn it and turn relay ON relay, if a dutycycle match occurs. Will this system work fine?
