5.1 volume control

kousalya_prasad · June 13, 2021, 5:36pm

hi there!
I am working on a project where I have to control individual channel volume using r2s15902fp IC. I have a code for just to control whole volume but not individual channels(left, right, front, woofer). I am attaching the code I have below here. please help me in programming.
:

Read the forum guidelines.

Use the IDE autoformat tool (ctrl-t or Tools, Auto Format) to indent the code for readability before posting code.

Post your code in code tags.

johnwasser · June 13, 2021, 8:59pm

kousalya_prasad:

  Slot2(0, vol, 0, vol); // gain0, volume0, gain1, volume1
  Slot3(0, vol, 0, vol); // gain2, volume2, gain3, volume3
  Slot4(0, vol, 0, vol); // gain4, volume4, gain5, volume5

It looks like you can set 6 different gains and 6 different volumes. You just have to decide how you want to control each.

kousalya_prasad · June 15, 2021, 6:29am

thanks for the reply sir. I'm unable to find how to write code for it. could you please help!!
here is the datasheet of r2s15092fp IC https://www.renesas.com/us/en/document/dst/r2s15902fp-datasheet

Are you saying that you did not write this code and you have not figured out what it does?

It might be easier to figure out with less compressed formatting:

No ,I did not mean that .Again thanks for the reply. And I modified the code .thanks. and sorry I'm new to forum .

void audio() {
Slot1(in , 0 , lr , bass, treb, sr );
Slot2(0, lr, 0, lr); // gain0, volume0, gain1, volume1
Slot3(0, vol, 0, swr); // gain2, volume2, gain3, volume3
Slot4(0, sr, 0, sr); // gain4, volume4, gain5, volume5
}
