If you use the RDA5807 address of 0x10 the register addresses will start at 0x02 and auto increment, as stated in the video. However if you use the RDA5807 address of 0x11 individual registers can be accessed by sending the register address after the RDA5807 address, in the usual way. So setting the frequency can be accomplished by writing directly to just reg 0x03. The same applies to any other register. I used a Microchip Pic for control and the addresses were 0x20 and 0x22 for device and register addresses respectively.
I was somehow amused to hear actually statics on my first powerup and I played a little to get some more control. For some reason I can’t change the volume anymore ( it worked once ) an when I change the channel faster than -0.3 seconds ( after trying a potentiometer on a0 with no more sound after the fist tuning ) on my rotary the device will go mute… except in “direct mode”. Furthermore I can’t get a clear signal, neither in mono nor with a bigger antenna. Guess I will solder a second one to see what’s going on ( it’s unbelievable loud in the moment ), but thanks for your sketch, useful and structured layout for starters:)
Thank you for your video. But pin modes are not listed on sketch, maybe they may be detailed in the Library, but how do we know which analog pin to attach the potentiometer for tuning?
Hello, I'm also making an fm radio, I have a question. How does the RDA5807 noise canceling work? I don't want to hear the noise at empty frequencies. Is there a way to prevent it?
thank you sir! your video made my day! i'm struggling with the chip and your video clarified a lot for me!

A very useful video! Thank you!
And great your library! Thank you again!
Brilliant!

Nice video... can you confirm if the only library used here is the #include ?
thanks!
