Some good news.. mic select is working... also there is mic type. I think those will be easiest to implement.

Still no monitoring :(

ML21624 supports it... ML21621, its not mentioned in the crappy crappy datasheet.

The 1100D port will probably re-use your work. Great job!  ::)

I've set up some of the analog volumes and implemented the mic in/type controls.

Volumes get reset when you hit rec or play so its best to use them after recording is started or with the mic amp powered at stop. Figured out some of the bit setting. Still a bunch is missing.

Audio remote shot works if you power up the mic from debug first. Going to work on getting that to happen automatically.

Threshold while in photo mode is for some reason much higher.

into register commands. There is no DAPM unless you're using ALSA on something that can run it. It won't be in the firmware.

The only hints form the alsa dev list were:

Code Select

Let me discuss about intercon settings.

Anticipated routes are like below.
Analog MIC(single ended) -> PGA -> ADC -> SAI
Analog MIC(differential) -> PGA -> ADC -> SAI
Digital MIC -> SAI
SAI -> DAC -> SPOUT
SAI -> DAC -> LOUT
LINEIN -> SPOUT

Powered on the dac and headphone amp... hear hissing and it mutes when you tap the microphone. Can also turn on both channels of IC and move the stereo mic from right to left and back.

@1%

Did you write document which is clear thing?
I just want to help you mapping(confirm) register value and Alsa driver's value.
But I don't know which one is clearly understanding.

I created a wikia account and let me know which part is confirmed in source code.
I wil write to our understanding to wikia.

I'm not perfect understanding.
But now I can use ptp on my win 7 x64.

Let me confirm what you need:
Collect a memory value for each modes(normal,recording, play, palying)


First testing .
QuoteDAC (digital->analog) (550D and 600D, bcoz handled by tx19a I think)
StopASIFDMADAC=
0xC05000B0 <- 0
0XC092020C <- 0
-

normal:
<conn> m 0xC05000B0 16
c05000b0  24 00 00 00 00 00 00 00  07 00 00 00 00 00 00 00  |$...............|

recording:

play mode but not play:
<conn> m 0xC05000B0 16
c05000b0  24 00 00 00 00 00 00 00  07 00 00 00 00 00 00 00  |$...............|

playing :

c05000b0  27 00 00 00 00 00 00 00  07 00 00 00 00 00 00 00  |'...............|


Are these correct understanding? Is it a helpful for you?

That is a canon function... you want audio_ic_write or read for direct communication. When I looked at that function in firmware it basically does a bunch of IC writes and leaves things muted till you actually play a file. Also sets up buffers for playing/writing, etc.

I can already turn the dac on and hear stuff... I just can't send it through mixer, etc.

The registers in audio.h are pretty much right.. just their values are not all known and there are a few extra in canon firmware I'm going to have to find.

In the alsa file the registers are even, in camera they are odd but the same thing. We have same value in the even registers but for some reason it doesn't change.

audio_ic_write( ML_PW_SPAMP_PW_MNG | 0xff ); // power speaker amp FF, BF no difference: is amp power 1f is speaker bf is headphone or "AV"
audio_ic_write( ML_PW_LOUT_PW_MNG | 0xff ); // Line out PM to all ON ... I think this is line out amp: same deal?

audio_ic_write( ML_PW_DAC_PW_MNG | 0x02 ); // power up dac  : Dac comes on but I don't think audio is being amplified at all, very very quiet.


Problem is IC has modes play and rec so I think we have to skip canon and just control it directly.  I tried to make a hybrid register setting between rec and play but it didn't make a difference.

for easy to understanding.
I will check your debug.c

And I found this on ml26124.h
Code Select

        /* Record/Playback Running Control Register */
        if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK)
         snd_soc_update_bits(codec, ML26124_REC_PLYBAK_RUN, 0x2, 0x2);
        else
         snd_soc_update_bits(codec, ML26124_REC_PLYBAK_RUN, 0x1, 0x1);


It this a something help to understanding rec/play mode handling?

I'm really confusing... Sorry for can't help you.

In alsa driver  I fond
Code Select

#define DVOL_CTL_DVMUTE_ON       BIT(4) /* Digital volume MUTE On */
#define DVOL_CTL_DVMUTE_OFF      0      /* Digital volume MUTE Off */

static int ml26124_mute(struct snd_soc_dai *dai, int mute)
{
        struct snd_soc_codec *codec = dai->codec;

        if (mute)
         snd_soc_update_bits(codec, ML26124_DVOL_CTL, BIT(4),
         DVOL_CTL_DVMUTE_ON);
        else
         snd_soc_update_bits(codec, ML26124_DVOL_CTL, BIT(4),
         DVOL_CTL_DVMUTE_OFF);
        return 0;
}


So I think , we only to set this bit to 1 when we need to mute like this.
Code Select
audio_ic_write( ML_DVOL_CTL | 0x10000);

But your xmuteav() is a lot of audio_ic_write(). and in your xmuteav() had this:
Code Select
audio_ic_write ( 0x6908 ); // Set Dvol Stuff to "Play"

This means
Code Select
audio_ic_write( ML_DVOL_CTL | 0x1000);

I found matching item for this in alsa driver
Code Select
SOC_SINGLE("Digital Volume Fade Switch", ML26124_DVOL_CTL, 3, 1, 0),

You descrived "Set Dvol Stuff to "Play"" but it means Fade Switch will switching to ON.

How did you know those register values in debug.c?

These have no maximum value definition in alsa driver. So I guess it's READ ONLY register.

Dvol control has lots of switches and yes a mute... I made a mute/unmute and it seemed to work but camera would stop recording when sound stopped flowing to the buffer.

I got most of the functions from http://magiclantern.wikia.com/wiki/600D/Audio they came from the firmware.

As far as I know audio IC write can only write one byte. So you cannot write 0x1000 because you're writing 00 to register 0x10 which is probably 0x11 or "software reset".

I was way more confused when I first started... and I don't know how right I have the bits.


Code Select


DVol -0x69
11111111
   xSOC_SINGLE("Play Limiter", ML26124_DVOL_CTL, 0, 1, 0),
      x SOC_SINGLE("Capture Limiter", ML26124_DVOL_CTL, 1, 1, 0),
    x   SOC_SINGLE("Digital Volume Fade Switch", ML26124_DVOL_CTL, 3, 1, 0),
   x    SOC_SINGLE("Digital Switch", ML26124_DVOL_CTL, 4, 1, 0),
0001 0000 - Digital Switch (mute?)
0000 x000 - Digital Fade
0000 00x0 - Capture Limiter
0000 000x - Play Limiter

0011 1110 - 2c Rec - value of dvol in rec
0000 1000 -08 Play 
0010 1110 2e          - that ASIFMDAC function sets this too
0011 1110 then 3e  - then sets this
0011 1110 Mute AV 



So if you look at that, the switches are all there but I don't know if my bits are moved over by 1 or in the right location.
Of course no SOC single function in the camera so can only switch bits manually. I found some values by looking at what value the camera was writing and then converting to bits. Combined with the alsa driver you can then figure out what gets switched on and it mostly corresponds.

So with this information I make up my own value and see what it does. 0x13 is rec/play. In rec it is 11 and in play it is 12.... so I change that to registers and try to turn on both so I write 13 to experiment so (0x1313)

and etc, etc,

>>>>

Cannot be read only... camera sets it... no max value because its a power control register.

I may be able to help with this, i worked with the 500d audio chip a lot last year. Is there a factory documentation for the audio chip? This is what I used when working on the 500d as it tells you exactly what registers to modify for certain features.

Here's some tips:
Code Select

static inline void
audio_ic_set_mgain(
                                   unsigned             mgain
                                   )
{
        unsigned sig1 = audio_ic_read( AUDIO_IC_SIG1 ); // Read the value of register 'Signal Select 1', store it in sig1.
                                                                                                        // We will use this later when we set individual bits on/off for
                                                                                                        // different gain values.
    unsigned sig2 = audio_ic_read( AUDIO_IC_SIG2 ); // Read the value of register 'Signal Select 2', store it in sig2.
   
       
    // Setting the bits for each possible gain setting in the 500d, individually so it's easy to understand.
        //              - 24 hours ago I didn't even understand how to configure the audio chip, so I think this is pretty good
        //                for my first implemenation :)
        //
        // Basically, different gain settings use different combinations of the MGAIN0, MGAIN1, MGAIN2, and MGAIN3 bits being set/cleared.
        // Here's a reference table for the settings, taken from the pdf linked from line 201 above:
        //
        //---------------------------------------------------------
        // MGAIN3  |  MGAIN2  |  MGAIN1  |  MGAIN0 ||  Gain Value
        //---------------------------------------------------------
        //    0    |     0    |    0     |    0    ||     0 dB
        //    0    |     0    |    0     |    1    ||   +20 dB (default setting)
        //    0    |     0    |    1     |    0    ||   +26 dB
        //    0    |     0    |    1     |    1    ||   +32 dB
        //    0    |     1    |    0     |    0    ||   +10 dB
        //    0    |     1    |    0     |    1    ||   +17 dB
        //    0    |     1    |    1     |    0    ||   +23 dB
        //    0    |     1    |    1     |    1    ||   +29 dB
        //    1    |     0    |    0     |    0    ||    +3 dB
        //    1    |     0    |    0     |    1    ||    +6 dB
        //---------------------------------------------------------
        //
        // So my switch statement below looks at the value of the mgain variable (which is changed by the gain setting in the ML menu),
        // and sets the correct combination of bits accordingly.
        //
        // &= ~(1 << x) means clear bit x
        // |= 1 << x means set bit x
        //
        // That should be enough to bring anybody up to speed on things.
        // -Coutts
    switch (mgain)
    {
        case 0: // 0 dB
            sig1 &= ~(1 << 0); //clear bit1 [MGAIN0] in register 'Signal Select 1'
            sig1 &= ~(1 << 1); //clear bit2 [MGAIN2]    "
            sig1 &= ~(1 << 3); //clear bit3 [MGAIN3]    "
            sig2 &= ~(1 << 5); //clear bit4 [MGAIN1] in register 'Signal Select 2'
            break;
           
        case 1: // 3 dB
            sig1 &= ~(1 << 0); //clear MGAIN0
            sig1 &= ~(1 << 1); //clear MGAIN2
            sig1 |= 1 << 3;        //set MGAIN3
            sig2 &= ~(1 << 5); //clear MGAIN1
            break;

Different chip... no MGAIN or any of that: completely 100% at odds with old audio.c

No documentation except for 7k0r programming guide and alsa driver for the next IC model up. When I tried to get info out of the company they cried about NDA with vendors because audio ICs are TOP SECRET.

Who made the IC in the 500D?

For 500d:

I didn't so much mean to follow the MGAIN stuff, moreso look at how I set individual bits for the MGAIN registers. Thinking of things in binary may make it easier to understand.

And checking technical question form.
But it for customer?only,, because it need a "describe product name" and "plan for volume production"....
I guess they are not give us the document. maybe,

Yea, I already got the english 7k0r guide, the other one looks the same but its a little bigger. The datasheet is more of a product announcement.

If you find more than in the english version, let me know but from a cursory look its the same.

English version is U19514EJ1V0AN00.pdf ... just type it into google.

First log:

2nd log: Recording turn on Capture Limiter and changes mic input volume.

Others... you're losing settings when rec/play/run goes to 00.

In one log
-ML_FILTER_EN 0f
+ML_FILTER_EN 00

Turns off filters.

All copies of the real registers in random unrelated spots, does not apply.


One thing strikes me though. Do volumes actually go down from FF to 10 or something like that... ff being lowest. And
L_MIXER_VOL_CTL is it 10 or 00 when recording. Which one is mute? I may have things backwards with this.
