Ok, trying to figure out the volume scales.... maybe someone knows math

Code Select Expand


DECLARE_TLV_DB_SCALE(name, min, step, mute) \

#define SOC_SINGLE_TLV (   xname,
  reg,
  shift,
  max,
  invert,
  tlv_array
)

static const DECLARE_TLV_DB_SCALE(digital_tlv, -7150, 50, 0);
SOC_SINGLE_TLV("Capture Digital Volume", ML26124_RECORD_DIG_VOL, 0,
0xff, 1, digital_tlv),
SOC_SINGLE_TLV("Playback Digital Volume", ML26124_PLBAK_DIG_VOL, 0,
0xff, 1, digital_tlv),



How do I do gain to db?  I can't figure out how DECLARE_TLV_DB_SCALE arrives at db value. Can't find it in the alsa sources.

Also HV20 and HV40

I'm going to keep trying, going to put register names in the functions. Here is a list, not 100% complete but getting much much closer. Some registers control more than 1 "thing", depending on which bits you flip.

Going in audio.h

Task override may be flipping things because while all of the magic lantern registers are wrong they still modify the real ones. I can disable the override and still power up the mic amp and get audio. Only on 1 channel until I start recording. Want to get the old registers out asap. This audio IC works fairly differently than the other one(s). Much of audio.c has to be different.. I see why this was a huge problem having no camera to test on.

With ML menu in play mode... I can unmute AV and listen through headphones at will.. wheel even adjust volume but there is not much latitude.

Docs for very similar lapis chip... may shed some light


http://us.generation-nt.com/patch-v3-sound-soc-codecs-add-lapis-semiconductor-ml26124-help-205578541.html



http://git.alsa-project.org/?p=alsa-kernel.git;a=blob;f=sound/soc/codecs/ml26124.c;h=22cb5bf59273dcbfde850dd6243a138cbdce003f;hb=HEAD

Registers are very similar as you can see:

http://git.alsa-project.org/?p=alsa-kernel.git;a=blob_plain;f=sound/soc/codecs/ml26124.h;hb=HEAD

The C file will show how to do stuff.


*It uses the other set of registers... ie. this ic is

#define ML26124_PW_MIC_IN_VOL      0x32
#define ML26124_PW_MIC_BOST_VOL      0x38

We use 33 and 39... but I think either address works for setting. Will have to test.... does this mean audio is done for us?

The odd registers are used. Making a list with values I've seen. I stink at bit operations so its a little hard.

i.e. SOC_ENUM_SINGLE(ML26124_SAI_TRANS_CTL, 6, 3, ml26124_companding);

That is put companding in CTL with offset of 6 and bitmask of 3 but what is a bitmask of 3?, and how can it be at offset of 6?

Code Select Expand


0000xxx ?
000xxx0 ?


Also shit like this:

snd_soc_update_bits(codec, ML26124_SW_RST, 0x01, 0);

Analog gain is mic input gain. L-gain is mic boost. Values are wrong.. I dunno what it was being set to originally. The db's don't correspond to anything.

I want to make a big chart of all of these regs from 7k0r and what values I find from canon. Some of  the registers are actually binary so depending on what bit is flipped some shit happens.

Once we have a full list it will make more sense what has to be done to control things. I'll mess with the play mode, I think you can get headphone to work if you unmute it right before you press play. If you do it while playing it will do nothing or just shut the speaker off. I found this out when I was originally doing msleep and unmute from the don't click me menu. The timing has to be right so canon doesn't change it back. With power up mic, audio remote shot can probably happen already.

I have to set the play mode up but I think i can find mic select. When I just start the amp up its only on 1 channel. after record it is on both.

*

The play filters mostly ser eq's and volumes.  The HPF from the 7k0r menus seem to work. Also rec/play toggles affect things.

I think reboot doesn't work but you can power mic amp whenever now and get left working at least. How do I enable ML menu in play mode?

I set the 2 first volumes up... there is just no latitude. Values being placed in those addresses aren't right. That is why I enabled the sound override task. I can try to disable it... maybe it will be more interesting.

When you mute av it does:     audio_ic_write( 0x693e );

None of the other commands write to 0x69 which I think is volume control enable/disable or something along those lines.

I have to put in a few more today like the mic power/unpower, reboot ic, enable IC, etc. Also was going to put delays to get to play mode... but I can just enable ML menu to show up? That would be sweet. After that I'll try some functions from the 7k0r sheet.

I can get the ext speaker to pop (like headphone) but I think only when something gets crashed/changed. It did it in record and stop but its hard to reproduce.

Seems continuously and whenever an action is performed. I.e I unmute headphone and its muted right away. When I set msleep to 4000 I can't get headphone to work, when its  2000 I could catch it and one file would play through headphones. As soon as you pause / play it goes through the speaker.

It only sets what it knows to set though since you still hear click when you press rec. 

PTP will kinda prevent using the headphones... guess I'll have to figure out how to send audio to the speaker instead. Will get a little more clear when you can read/write to the IC without having to turn the camera off/on/recompile, etc.

If I can call audio writes and reads from PTP I can try some things in the doc/canon + functions and then see what it does... Also it will be easier reading specific registers without having to dump all of them, turn off the camera, etc.

Wish it was like javascript console.. you just call functions and they run.

0x3900 is Mic boost for sure... when I turn it down external mic gets underpowered and internal mic is quieter.

0x3300 is input volume... I threw it on the first volume slider and it *somewhat* works.. mic gets quieter/louder but I never set up what it was putting in the register so its hit or miss.

0x3F00 is AV volume
0x3B00 is speaker amp volume its set to 1b for some reason...


I think I'll have to figure out the PTP.. .this is getting tedious. Canon functions always reset the registers so getting any setting to stay is pure luck.

The stuff from the 7k0r PDF pg107 on is helping, its mostly the same. There appear to be order/timing specific things to get the IC to do what you want and canon FW is screwing that up most of the time.

That seems like just as much work

Here is play mode.

One of those might be what is flipping/ignoring registers? Or you need to unpower amp to switch wind screen?

No way to send audio writes real time so I don't have to recompile and run every time? SD reader is on my render box and compiling machine is an extra laptop with no slot.

I wish I could look for more but I can't decrypt the firmware ( no keys) and I don't know how the dumper works for 600D or if it works. Only other option is trial and error? How can I make reg dump in play mode? Set msleep to some number then go into play? I'll look at take SS in 10sec.

I was doing too much work naming the registers. Wonder what is resetting things after register is changed. Maybe some process controls audio and has to be shut off? Or specific order needs to be followed? I'll have to try more stuff.

Here are some of the guesses/logs from trying if you didn't see it before:

Also, have to say many of the registers from 7k0r guide are the same or very similar.

Also i think setting 1 of the register pairs is enough... that seems to be what cannon fw does.

Try in MF too.

I played this function via audio writes and I can hear clicks then always a click when I start/stop recording.

On playback if I hit play fast enough after running the function I can hear audio from file in headphones.

TurnAVLineMuteOff=
0x5703   -< Disable Something else?                       
0x4903   -< This is disable amp?                         
0x4B00                           
0x3F33                         
0x2502                           
0x27A0
0x2126 -< I think this reboots IC.
msleep(0x1fe) <-  msleep(501ms)
0x4901 -< turn on audio amp
R0, R0, #0x6B00 -<< Send 10 to register ( off is 00)

When I play I think monitoring is on for few ms or completely but output is low or something is muting it?

Also when I run function I see audio meters fall while IC reboots and you can hear it in the video file on playback  [ now over headphones ]

Press Q you get the menu.

You need more batteries.. . they are ~$5 USD for me. Other things may drain your battery.

When not recording I can only get the meters to come on for a second when first enabling audio and then they fall. Maybe one of the other settings is set? Or do you need headphone to be on too for output volume?

I've got a slightly better understanding on how this works after some research. I have the console going, just need to decrypt .fr so I can load it. Wonder if you could do a detailed cross analysis between all available firmware and if that would help any.

I want to try:
call("TurnAVLineMuteOff");

with don't click me button... maybe while recording and while not with headphone connected and on.. I think I have to disassemble FW and find entry address and put it in the stubs? I can't just call it without that, right?

I've tried setting

7e ->  04
7f  -> 04
(On is 07)
to turn off wind filter. register changes but setting doesn't... at least I'm starting to know what is what. I'll try to find record volume next.

Evenly light green screen. Expose for subject. Convert the video file to some intermediate.

False color has a green screen mode too, might help to see how uniform the screen is.

You need to get an adapter. I use that for my crappy nikon manuals. It has AF confirm.

As for the 28-135, I have the ancient 35-135 and only used the new one on my friend's 7D. It seemed comparable,  sucks if its not as good. The HSM AF was better than my simgma 70-200 (RIP). Of course performance of a F/4-5.6 not so hot. Now they dropped it to 3.5, probably only around 28mm. Also I see the price is 450USD.... I got my lens for ~100 so at that price its a steal. At $450 you have other choices.... at ~$200/250 maybe it wouldn't be so disappointing? WTF canon.

Wouldn't it just be ISO 3200 + like 3 or 4 EV of gain?

Just like sRGB vs Adobe RGB.

Try it. Probably won't work.  Iso 80 can happen in movie mode. Maybe drop more than .3 ev and see what happens.
