I have an application where it will be cheap and convenient to use a low power FM receiver to manipulate a remote unit. The remote unit is to be cheap and low power. I'm looking into using a stereo FM channel to supply I2C signals (SCL\SDA) to a set of peripherals so I won't need an MCU. Specifically, I want to set digital potentiometers such that LEDs turn on and off. It seems like somebody may have proven this out already, but all the searches for FM\I2C get hijacked. Any hints?
I'm also looking into receiving data via FM as well. I can see in the below thread that people have made I2C slave mode work. Theoretically, a stereo channel could do unidirectional downlink. Similarly, a stereo channel could also provide two UART Rx channels. I'm looking for projects where people have done this, but I can't find anything yet. This seems pretty simple, but I'm suspicious because I see no implementations.
Given a Teensy4.1's abundance of communications channels, I could really get a lot done with a bank of cheap receivers.
