If we look at this code: #include <SparkFunSi4703.h> #include <Wire.h> int resetPin = 2; int SDIO = A4; int SCLK = A5; int STC = 3; Si4703_Breakout radio(resetPin, SDIO, SCLK, STC); int channel; int volume; char rdsBuffer[10]; void setup() { Serial.begin(9600); Serial.println("\n\nSi4703_Bre…

[image] outbackhut: (Hope that's the right category? @moderators ) It's close enough.

It takes about 5000ms to read the RDS on a lot of stations, but I need 100ms or less. NO STATION displays data when the timeout is 500ms or less. Some stations take up to 12000ms.

Here is another library for controlling them....Appears to be non-blocking. GitHub - mathertel/Radio: An Arduino library to control FM radio chips like... master An Arduino library to control FM radio chips like SI4703, SI4705, RDA5807M, TEA5767. - GitHub - mathertel/Radio: An Arduino…

Sadly that library doesn't seem to document available commands, and I also can't change the frequency. It seems permanently set to 87.50

The available commands are seen by viewing the source....I agree it isn't as nice as sparkfuns lib. [image]

Frequency is hard coded in the examples sketch....However I don't know if you modified the code.

Yeah, I put in a bunch of different frequencies, but the Serial monitor always returned 87.50. Must admit, it's no where near as good as SparkFuns library.

Here is another library specifically designed for the Sparkfun boards. GitHub - csdexter/Si4703: Silicon Labs Si4703 FM Stereo/RDS single-chip receiver... master Silicon Labs Si4703 FM Stereo/RDS single-chip receiver HAL library for Arduino - GitHub - csdexter/Si4703: Silicon Labs Si…
