Behavioural mixed-signal modelRDA5807M (RRD-102)rda5807m
RDA5807M FM receiver (module RRD-102, I²C)
Behavioral model after the datasheet: I²C 0x10/0x11, registers 02h–0Fh, tune/seek with STC, RSSI, stereo, RDS (station name 0A, radio text 2A), volume 0–15. The stations are in the "Stations" parameter (MHz|name|program|dBµV|radio text). Without an antenna on ANT 25 dB weaker.
