i built a digital radio using the si4732, i got most of it up and running like tuning, am/fm selection, channel seek etc.. but i cant get the volume or mute to work.
i xmit 0x4000 then 0x000a to try and lower the default volume of 63 to 10 but it doesnt change. same with the mute, i xmit 0x4001 then 0x0003 but i still get l+r outputs...
any suggestions?? thanks
For the first time, no request for schematics as You've manged a lot.
But.... can You post a link to the datasheet/owners manual to the si4732?
silabs an332
its 313 pages but you'll only need the fm rcv section
finally! i got it! i forgot to put 0x12 before volume subroutine, thnx
