AR1010 FM Radio
We chose to use the AR1010 FM Receiver module for our radio component. Addressable over I2C, we could tune to specific stations or seek at an adjustable sensitivity level. The documentation from Airoha wasn’t the best we had ever seen, and it took some work to come to a consensus on some specifics of the architecture. We found several documents and code portions that seemed to conflict in the exact operation procedure. Eventually we found the right combination of register settings, and the chip came to life. Using only a piece of 24AWG wire as an antenna, the analog audio outputted from the device sounded fantastic, even down in our underground cement-walled lab. We also hope to provide this code in the future to the SF community as a baseline standard.
