FM Radio on the Nook?

Has anyone tried this? We have the hardware behind it (twl6040).
I compiled the driver for it, and found the firmware blobs it wanted to load.
Insmod dmesg logs:

No audio. I'm not sure if I just need to use a mixer to map it or if I have further driver problems.
Sometimes I get these errors?
Code:
<3>[ 3081.753814] fmdrv: Response SKB ptr not NULL

<3>[ 3082.531036] fmdrv: Response SKB is missing
Anyway, I'm thinking it's possible with some work.

Well I definitely know that it's going to be possible with a little bit of work.
I managed to get a split second of audio from radio station while I was messing with spirit radio settings and unplugged the headset.
Don't know what I did because I haven't managed to recreate, but it was enough to let me know that it was there and just needs to be mapped.
If anyone else would like to work with me on this, here's the files:
http://www.mediafire.com/download/6296mev66ydlb2y/fm_radio_files.zip
the *.bts files go in /system/etc/firmware
fm_drv.ko goes in /system/lib/modules
omap audio-tool (which I just compiled) goes in /system/xbin
You have to procure spirit FM unlocked (from market or elsewhere).

I'm not going to get involved but that's cool and unexpected. Good stuff.

Well at least I found a practical use for audio-tool. Apparently our sound chipset is normally configured for low-power operation. You can use audio-tool to change this to high performance.

[MIUI] Enable 24bit as default audio output and Other Sound Modifications [Testing]

Any damages of hardware or software if happen, I'm not responsible. I'm using it with sound mods, all are still stable and fine. But you are warned!..
Also this thread and whole modifications are written by my personal experiences, all the features, testing and working things. Some info can be wrong. I'm still learning.
Updated: 11th January, 2019. Thread expired, update may come soon. Don't follow these for now.
Hi. I've been on personal sound modding for a while and made a few successful attempts. The most important thing I've done is this one. This 24 bit sounds incredible, until I've found the Ainur Sauron manual modifications, sounds even better. I'll give everything simply here.
Flashing and Instructions:
MIUI - View attachment 4645100
Others: I'll update soon.
Optional(confirmed by me fully):
Check this post - MIUI Sound Mod for the best ever sound experience in MIUI(with other mods). All have been tested by me.
Optional 2:
Flashing Ainur Sauron mod with few modifications (MIUI):
Extract and copy any(48khz is recommended) sauron_useroptions file from this zip - View attachment 4645096 in the root directory of your internal storage (not in any folder).
Install Ainur Sauron in magisk.
Details:
Ainur Sauron sound mod is different. You won't see any app or UI, but you will feel massive differences in sounds. As it's name driven from Sauron, the all seeing evil (you can't see him, he will see you). It has few great features which can be only enabled manually. I enabled these- qcom Audiosphere, Shoebox, and 24 bit(only changing here I didn't see changes in terminal too, so I still modified my files. But check by yourselves).
You can also check all of the options in sauron_useroptions and enable manually. Now I'm using 96khz(check MIUI mod), aptx, impadence of earphone(power output through the jack) too. I still haven't found mass differences in these, needs testing, but I think some of it's working.
I've found installing this with 24 bit enabled makes sound stable and more beautiful.
If you face any problems(may not applicable to post 13):
1. Uninstall all sound mods previously in magisk, reboot(?), install 24 bit, install Ainur Sauron (if you want), reboot(?), install your desired sound mod.
2. Getting 44100 hz sampling rate? Install viper4android later.
3. Make a clean install, without any other sound mod(for the best experience, if any sound mod interfering with these). The mods provided here, are working fine, if you didn't mess up with anything.
4. Don't remove or patch deep buffer. Also don't use audio compatibility patch. - I don't know much why sounds different.
Checking:
While playing a audio, check in this kind of paragraph in any terminal emulator saying - Standby as no.
Code:
su
dumpsys media.audio_flinger
Example 16 bit,
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Example 24 bit,
If the HAL and processing format is pcm24, then it's perfectly working. If any music player uses directly 16 bit output in own state, this may not work. Tested with Sony music player, MX Player with video(no sw audio rendering), works fine. Also test gaming. Feel the sound too.
***I only increased default speaker and earphone/headset output. Bluetooth, cast, sink(?) etc may use 16 bit. No support from me now, there's a reason.
Every notes and details will be noticable, just keep listening quietly. You will find nothing missing in your music sound when you hear, if it works.
Try with full sound.
I didn't increase telephony output, not now. It will show as pcm16. Didn't try to increase the sampling rate, really unnecessary as in this way, but in Ainur Sauron, seems fine. Thought of 32 bit, but we, human can't understand difference between 24 and 32 bit audio.
Lastly few talks: Our phones speaker isn't made for 24 bit output, but it works fine, though has side effects, you will find out*. With earphone/headset, sound perfectly fine.
There will/may be incompatibity with any sound mod, but they will/may work fine, you will find out*.
The difference in overall sound is noticable a lot. There will be change in sound volume and range, you will find out*. It's really astonishing, where its the default output. It's real. You will find out*.
Also, headache issue because of hearing, it's also different. You will find out*.
*when you hear...
I've a hard schedule, I may update this thread with details later.
And lastly, you will feel the power of the sound your phone can produce.

Great work man!

*new update, MIUI only.
*new v3.
Changes: fixed little mistake done by me, v2.
fixed mistakes, v3.
fixed twrp flashing script, v4. This one seems stable, no update will be provided for a long time, MIUI.
notes added. check. my fault.

Thanks a lot!
A changed sample rate to 192000 in the 3 files, and it seems to work. Can you test it?

Thanks, but no need to test by me. I know it's working, also the screenshot proves. I didn't increase it, as I've found 48khz is enough and good, also I've searched and checked sound wiki, and related while I was in modding. Still it struggles a little while playing 24 bit output.
I'll check and fix, and give other updates as optional as experimental for 96khz and 192khz(with your files, need few edits) sooner or later.

Oh. Actually power output of our phone through earphone/headset port is lower, I tested few earphones(hi res too) with other phones, ours gave poor quality. Found its power output.
24 bit actually increases audio quality, not electricity through the port. Tested yesterday. You should be using them, if you are referring to this. Otherwise, kernel or hw modifications should be done for increasing power output.

im using BGVP SGZ DN1, i guess that earphone doesnt need much power like high end earphone or headphone, but i really waiting for next update

Update for RR Luis Oreo and Arrow Os Pie
[experimental] I didn't test these by myself. Helped and tested by @brunozod and @ordinarystar. Only for RR Luis Oreo (based on Los official 15.1 vendor) and Arrow Os pie. May/should work on other oreo/pie ROMs too. Not tested. Arrow Os pie version may work in all ROMs based on swapnil soni vendor(pie?), RR Luis version may work in Los Official 15.1.
I was sured it's working, the terminal, and they heard differences while playing a song.
Issues:
*Mod not working? Uninstall all sound mods in magisk, reboot(?), flash this mod, reboot(?), install your desired sound mod. But check in terminal.
*If you have 44100hz output, also different things(you will find out), install viper4android, check again.
{Funny thing is that, each may work on both, but you are on your own}
Now this is experimental. I may update my thread tomorrow with details. Busy schedule.

Update for 96khz and 192khz(?) MIUI [experimental]
These are not tested by me (maybe never will be). But I configured the way these should work. You are on your own. Thanks @kennethstarr for heads up.
Note: these are experimental and will be for a long time. CPU usages, battery drain etc should be concerned only by yourselves.
* Bluetooth output, or sink output (?), cast may not include these output. They can be also 16 bit too. No update for them from me now. There's a reason. I'm checking. Earphones, default speaker should be fine.
*Viper, Dolby didn't work for me in 96khz, not tested 192khz, also no issues tested further in any of those. No support for them now.
If anything is missing or wrong, sorry. I'll update soon.

after flashing for arrow os pie seems good, my BGVP SGZ DN1 gain more power so i dont need to raise volume to 60% to get the detailed sound, (altpugh the bgvp no as good as TZF or OCHARAKU earphone) and second time i flashed the 24 bit 192khz the problem started, chrome wont loading page and Force close, and third time i try the 24it 96khz and seems working fine youtube and chrome totally fine.
I'll update again, hopefully there more people will tested it, altough redmi 4x sound chip not as good as LGv10 or V20, keep making good sound mod

Thanks for testing.
Actually, 96khz and 192khz up there are only for MIUI at this moment, I also mentioned it. Even on MIUI, after flashing 96khz, viper/Dolby didn't work for me. Didn't test further nor 192khz. I also mentioned them as experimental, I won't support them now, nor any bugs related.
I found 48khz is enough for our chip, battery and other things related to this. Even sounds better on 24 bit. So, I am seeing no support needed or I'll have my headache started again. Busy days...

Can you give me the output of the terminal command? Before giving surity of 96khz, I need to check it, the whole issue is different, because MIUI and treble ROMs have few differences in those files, you may not get bug now, you may get later.

It's showing PCM 16. Not working. There's file differences in MIUI and others.
I'll upload 96khz and 192khz output for treble ROMs tonight. Use code tag from the tab in the codes. Thanks.

Manually adjust brightness to maximum/peak brightness without being in sunlight?

(Please delete my previous similar thread)
Most modern phones won't reach peak brightness unless they are in direct sunlight (by the light sensor). The slider at maximum brightness isn't really the phone's peak brightness. The slider is "capped" unless one modifies it somehow (the idea is to protect one's eyes, save battery life etc...).
For example, on gsmarena the specs for the S23's display are: "1200 nits (HBM), 1750 nits (peak)".
So, the slider only brings the phone's display to 1200 nits, while the display's full capacity is actually 1750 nits.
I don't want "daddy Samsung" to decide when my phone can reach maximum brightness or not [even if it is to protect my eyes or save battery etc..].
So, how do I enable my phone [in any way necessary] so that I can manually adjust it to maximum/peak brightness via the slider, without being in sunlight

You can just manually play with the settings:
Code:
$ settings list system|grep bright
screen_auto_brightness_adj=0.0
screen_brightness=22
screen_brightness_float=0.08333588
screen_brightness_for_vr=86
screen_brightness_mode=0
$ settings put system screen_brightness 100
Many LCD screens (and eInk screens) use the venerable TI LM3630A chip as LED driver.
Just find under /sys/devices/platform/<somewhere I²C>
I just looked and my Moto G is using a AW99703 instead.

Oh, interesting! But I'm in a bit over my head here...
Should I start by looking for a file named "TI LM3630A" somewhere within /sys/devices/platform/ ?

It's not that complicated:
You can manually set the brightness with similar settings command (note: brightness could go to 100 or 255 or anything).
You could write a tiny app that just used the Android Java Settings.
Of course you'd have to have <uses-permission android:name="android.permission.WRITE_SETTINGS"/> in your AndroidManifest.xml
You could interact with the Linux driver. You have to enumerate:
Code:
# cd /sys/class/backlight/
# ls -l
lrwxrwxrwx 1 root root 0 1971-12-21 10:12 warm -> ../../devices/soc/c1b6000.i2c/i2c-6/6-0038/backlight/warm
lrwxrwxrwx 1 root root 0 1971-12-21 10:12 white -> ../../devices/soc/c1b6000.i2c/i2c-6/6-0038/backlight/white
# cd warm
# ls -l
-r--r--r-- 1 root root 4096 2023-06-17 09:04 actual_brightness
-rw-r--r-- 1 root root 4096 2023-06-17 09:04 bl_power
-rw-rw-rw- 1 root root 4096 2023-06-17 09:03 brightness
lrwxrwxrwx 1 root root 0 2023-06-17 09:04 device -> ../../../6-0038
-r--r--r-- 1 root root 4096 2023-06-17 09:04 max_brightness

-r--r--r-- 1 root root 4096 2023-06-17 09:04 type
-rw-r--r-- 1 root root 4096 2023-06-17 09:04 uevent
If you alter this unilaterally you'll have to come up with some way to reconcile it with the settings.
You could interact directly over I²C to the chip itself, but you have to read the datasheet and know what all the numbers mean.
Code:
# ./lights
warm i2c-6 38
00 Control 06
01 Configuration 18
02 Boost Control 58
03 Brightness A 2f
04 Brightness B 6f
05 Current A 0a
06 Current B 0a
07 On/Off Ramp 0a
08 Run Ramp 0a
09 Interrupt Status 02
0a Interrupt Enable 00
0b Fault Status 00
0f Software Reset 00
12 PWM Out Low 00
13 PWM Out High 00
1f Revision 02
50 Filter Strength 00
white i2c-6 38
And you could fry stuff by writing the wrong numbers.
I did all this stuff for an app for my eInk device that uses two color temperatures of backlight. The stock controls were crap.
So I wrote my own that just used /sys/class/backlight/...
Oh, it could be that some limit is set in the DTB itself:
Code:
029260 [email protected] {
029270 compatible = "onyx,lm3630a";
02928c reg = < 0x38 >;
02929c status = "okay";
0292b0 lm3630-vdd-supply = < 0x18b >;
0292c0 lm3630,en_gpio = < 0xa1 0x4c 0x0 >;
0292d8 lm3630,bank_sel = < 0x6 >;
0292e8 lm3630,bank_swap = < 0x0 >;
0292f8 lm3630,linear_output = < 0x0 >;
029308 lm3630,max_current = < 0xa >;
029318 lm3630,default_brightness = < 0x0 >;
029328 lm3630,max_brightness = < 0xff >;
029338 lm3630,pwm_enable = < 0x0 >;
029348 }

Wow, this is way beyond my comfort level. I'll ask my programmer friend if he can help me based on what you have written
Much appreciated!
