What changes do you have to make? I have never been able to get it to work.

Max

here is how it is implemented. The first case is the default (both pins pulled up).

#define FIRSEL_LOWA 6,2,0,0b001
#define FIRSEL_LOWB 6,2,0,0b011
#define FIRSEL 6,2,0,0b000
#define OSR_LOW 7,6,5,0
#define OSR_MED 7,6,5,1
#define OSR_HIGH 7,6,5,2

if (bit_is_set(PINB,PIN3) && bit_is_set(PINB,PIN1)) {
setRegBits(FIRSEL_LOWA);
setRegBits(OSR_LOW);
}
if (bit_is_set(PINB,PIN3) && bit_is_clear(PINB,PIN1)) {
setRegBits(FIRSEL_LOWB);
setRegBits(OSR_LOW);
}
if (bit_is_clear(PINB,PIN3) && bit_is_set(PINB,PIN1)) {
setRegBits(FIRSEL);
setRegBits(OSR_MED);
}
if (bit_is_clear(PINB,PIN3) && bit_is_clear(PINB,PIN1)) {
setRegBits(FIRSEL);
setRegBits(OSR_HIGH);
}

Depends on the sample rate out of the metronome.

Well i just got my volumite in the mail. From looking at a non programmer point of view; i have 4 possible combos from pb3/pb1, the first 2 are not use due to setting the bit rate low. So its either pb3 is grounded and pb1 is high, or pb3 is grounded and pb1 is grounded? PS: what is pulled high? does that mean if i dont connect it, it is high, or do i have to put 3.3v or 5v on the pin?


Now i just have to figure out the rest of switches and where to even connect the thing and im done. I hope i didnt buy a $30 paper weight, or worse yet brick my dac.

Ok really dumb question. So to get 96khz, i install r1/r2, leave PB3 nc, and ground PB1?

(I haven't read the whole thread in detail, so this may be repeat, but...)

This is what I used for s/w mode: http://hifiduino.blogspot.com/2009/04/success.html

Now, according to Russ, this is the code in the volumite:

---

#define FIRSEL_LOWA 6,2,0,0b001
#define FIRSEL_LOWB 6,2,0,0b011
#define FIRSEL 6,2,0,0b000
#define OSR_LOW 7,6,5,0
#define OSR_MED 7,6,5,1
#define OSR_HIGH 7,6,5,2

if (bit_is_set(PINB,PIN3) && bit_is_set(PINB,PIN1)) {
setRegBits(FIRSEL_LOWA);
setRegBits(OSR_LOW);
}
if (bit_is_set(PINB,PIN3) && bit_is_clear(PINB,PIN1)) {
setRegBits(FIRSEL_LOWB);
setRegBits(OSR_LOW);
}
if (bit_is_clear(PINB,PIN3) && bit_is_set(PINB,PIN1)) {
setRegBits(FIRSEL);
setRegBits(OSR_MED);
}
if (bit_is_clear(PINB,PIN3) && bit_is_clear(PINB,PIN1)) {
setRegBits(FIRSEL);
setRegBits(OSR_HIGH);
}

For 96K you want the registers set for OSR_MED

which is the following statement:

if (bit_is_clear(PINB,PIN3) && bit_is_set(PINB,PIN1)) {
setRegBits(FIRSEL);
setRegBits(OSR_MED);

This means:
- PIN3 is pulled down
- PIN1 is pulled up

Just to be complete

PIN1 PIN3 OSR
---- ---- ---
LOW LOW HIGH
LOW HIGH LOW
HIGH LOW MED
HIGH HIGH LOW

Nope setting it up just like the link didnt change a thing. I dont know what im missing, but reguardless of other settings or if the volumite is installed, if i put mode to Z all i get is modem noise.

Everything is float but mute=1

still modem noise

modem noise with i2s set to ground or 3.3v

If the volumite was misconfigured then i should get no noise, or possibly full volume.

I wish i knew how it should behave in software mode with no volumite. The volumite has no effect if its plugged in or not. and the chip is getting 3.3v (Feeding the reg 5v).

Ugh this is frustrating. Everything works. usb to met set to 24bit 96khz to upus to balisi lite. Its this volumite thats the only problem. If i cant get it to work, then im out 30 bucks, and i have to get a pot and a buffer to make this a preamp...

With both pb3/1 grounded, still modem noise with i2s on 3.3v or grounded. ya diff has been grounded the whole time.
