tune-s2 has a small quirk in it.

Using ATSC frequency tuning 617000 N 1000 I get Screenshot - 07022015 - 03:42:58 PM.png where modulation is QPSK and dvbtraffic doesn't produce traffic.


Using ATSC channel tuning 38 N 1000 I get Screenshot - 07022015 - 03:44:31 PM.png where modulation is 8VSB and dvbtraffic works.

I posted it here cause that is where I noticed it on the Pi.

Oh I had to load it on this kernel also after removing the other one.

I have issues with i2c also but I am hoping that might be remedied with i2c arm update.
My 3.19 kernel is handling i2c fine but that doesn't have updatDVB on it, and I would like to get them together.

DarkSky you know how to get make one Pi take orders from another Pi I believe. 
It's not a problem yet, but maybe later.

I want to see about getting my pi working on 12 with a regulator down to 5v thru the GPIO bus.
And also getting some Qt programs loaded.

ADDED:

A little leary of putting a link  for the new image but I guess it needs to be tested and go from there. Just put it on another sdcard to test with.

ray@ray-LX6200-01 ~/image $ md5sum rpi2b-clean_06-30-15.tar.bz2
a377295b2c9508b5b7edf366a8f57958  rpi2b-clean_06-30-15.tar.bz2

https://drive.google.com/file/d/0B-hVZ4SWSiuKbTRsd1FrTHZYMmc/view?usp=sharing

Directions:

Have a fresh fat32 formated sdcard ready in desktop
Run md5 sum on the tarball and verify
tar -jxvSf rpi2b-clean_06-30-15.tar.bz2

Find out where the sdcard is mounted:

ray@ray-LX6200-01 ~/Desktop $ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1       339G   59G  263G  19% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev            3.8G   12K  3.8G   1% /dev
tmpfs           774M  1.6M  772M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none            3.8G   68K  3.8G   1% /run/shm
none            100M   36K  100M   1% /run/user
/dev/sda6       178G  116G   53G  69% /media/ray/FILES
/dev/sdd1        15G   15G     0 100% /media/ray/3165-3137

Here mine is mounted on /dev/sdd1 so:

sudo umount /dev/sdd1
sudo dd bs=2M if=rpi2b-clean_06-30-15.img of=/dev/sdd    --no partition # here. This takes a while; wait for prompt
sudo sync

Eject the sdcard in file manager and remove it and then reinsert it to expand the file system. The upgrade from wheezy to jessie broke the resize feature in raspi-config. I have not figured out why yet. I have had issues in the past with raspi-config resizing and have never trusted it since even though the issue is supposed to be fixed so I always use gparted on my desktop to resize.

open up gparted and find the sdcard in the drop down window in the upper right hand corner
right click on the dos and ext4 partitions one at a time and choose unmount
right click on the ext4 partition and choose Resize/Move
In the box that comes up drag the arrow on the right hand side all the way to the right. Be sure it is arrow on the right
click Resize/Move button
click Apply All operations arrow in upper middle of gparted window
close out gparted
eject drive in file manager window
remove sdcard and put it in the pi and hook up all cabling and save the power cord for last

Login: pi
password: raspberry
FYI: root password is raspberry also

updatedvb:

In the settings window set up your devices. If you have a mpeg licence:
sudo nano /boot/config.txt
scroll down to the bottom and find this and enter you licence data and remove the #:
# decode_MPG2=00000000000
ctrl-x to exit and y to save
reboot

open up updatedvb and go to settings ---> General ---> Play cmd box:

Match omxplayer play area to you screen so it will not fill the whole screen with a 1.77 ratio. An example my monitor is 1680 x 1050:
1680 / 1.77 = 949.15 so 1680 x 948
The 40 drops omxplayer down below the top task bar

Put the command in the Play cmd box:
xterm -e /usr/bin/omxplayer -o hdmi --win "0 40 1920 1080" /dev/dvb/adapter{}/dvr0

click the save button and exit settings

This is a crude way to launch omxplayer but it lets you have use of omxplayer keystrokes which only works when omxplayer is launched from a terminal.
leave xterm open. If for some reason it gets unactive click on it's icon on the top taskbar
To kill use ctrl-c which kills xterm and omxplayer

After a while screen areas will go black outside of omxplayer. This is normal; wiggle mouse to get it back

Andy found that tune-s2 does not work. There was an upgrade on the modules it has to be recompiled:

open up a terminal
cd src
git clone https:bitbucket.org/majortom/tune-s2
cd tune-s2
./tune-s2 will run it. You can sudo "cp ./tune-s2 /usr/local/bin" if you want it in your path
remove old tune-s2 in /usr/local/bin if you did not copy as mentioned in previous lin

The link on the desktop to updatedvb goes to /home/pi/src/updatedvb. If udl does an upgrade on updatedvb:

open up a terminal
cd src/updatedvb
make distclean                ---Most of the time not necessary instead of make clean just clearing everthing out
git pull
/opt/qt5/bin/qmake .
make -j4

The desktop wallpaper I made is the size for my Monitor. Right click on the desktop --> Change Desktop Background
From there you can expand crop or whatever to fit your screen.


What Pi 2B OS are you using? to put this image on?

andy, consider that a feature encouraging you to be lazy like me...[biggrin]
I am lazy, and don't wanna type any more than I have to...
thus the take a stab at the SYSTEM using feinfo...

I did mention the channel numbers are only valid for atsc in the tune-atsc readme...
problem is ATSC tuners can also support cable TV QAM modulation in the same spectrum.
I don't know why dvbtraffic wouldn't work when not specifying the correct modulation.[confused]

The only reason VSB_8 gets tossed in there is this..
I admit, cheap and dirty...but it was good enough for me...

        if(info.type == FE_ATSC) {
            t.system = SYS_ATSC;
            if(t.freq < 52) {
                t.modulation = VSB_8;
            }

My image is a complete turn key operating system. It was made from the Raspian image downloaded from Raspberry pi's download page. I just adapted it to run the apps we use here.

I upgraded from debian wheezy to jessie
Compiled enough of qt to run and compile updatedvb trying to keep the size down of qt install
Upgraded the kernel from 3.19 to 4.1 with UDL's modified modules
Majortom's tune-s2 is there but needs re-compiling because of libs being upraded

All you need is a empty formated fat 32 sdcard to install it on.

I'm thinking some Raspian, some wheezy, some jessie and a good dose of v4l-updatelee.
DarkSky is a major chef when it come to Raspberry Pis. [thumb]

I put all my RPi2B OS's on 32G microSD's , there's room for expansion and They're Smokin Hot"!

I have been looking every day since you mentioned the i2c issue and there has not been any upgrade yet. I have not got anything here to do things like you do. So basically I know nothing about it to be any help. What problems are you having?

This question shot way over my head. What are you wanting to do?

So,majortom you're not going to put in zip-code option and build the tables for virtual channels?
Here 35 would go to 14, 23 would go to 16, etc.....[smile]

Your usage screen thru me a curve for a while..... I was adding 'ch' '[  ]' then I saw an ex: 18 N 1000 or similar ....... sometimes my nose gets in the way.lol

So frequency is there basically for cable??

Are you going to try gps with the RPi or have you already?

in a nutshell, yeah...if ya wanna do cable, specify the freq and modulation.
I am thinking cable gets used the least, so was easiest to let atsc/vsb use the minimum
specified parameters by using the rf channel numbers. Make the tethered folks work a little...

I haven't tested the gps receiver on the pi yet, but I don't see any reason why it wouldn't work. Sometime I wanna hook up with the LPTV station guy again and collect some more data on his transmitter. Our schedules don't exactly line up. Translation...he's retired from his real job, and I'm not.

"DarkSky you know how to get make one Pi take orders from another Pi I believe.

Well if I can't come up with a fix for I2C then I want an old kernel RPi that runs my I2C peripherals to take commands from newer kernel RPi that has updateDVB tuners on it. SSH  Master and Slave or Server Client set ups. I've not done much with that, I understand it, just not all the nuances. This is tied in with my az-el mover project which is still in embryonic stage. Gestation period might be a couple of years. lol

That postage stamp sized GPS for the RPi looks neat, although I just ran into a USB GPS that seems like a better GPS for less price, provided that it can be made to work with Linux.

About 25 years ago, I bought a couple computer interface boards that Magellan sold to people hoping to develop new GPS applications.  They were just circuit boards, and I had to buy cases for them, wire in on/off switches, add a power supply, add RS-232 port, add an external antenna, and write software to log all the RS232 data coming in.  The end product was a GPS that was about the size of an Azbox Elite, not counting the antenna or power supply, and had all sorts of wires running to it.  This monstrosity (one of which still works) is now replaced by something the size of a postage stamp, which is amazing. 
    My initial intent with the thing was to carry my laptop computer in the car, and have this GPS feed position data to plot my position on a map, and connect it to my mobile ham radio, and send the data back to my computer at home, all of which seemed amazing back then.  Getting the thing to spit out the data to the computer and ham transmitter was easy.  Turned out that the map was the hard part.  I got it working with some home-made low quality maps, but then I heard about a talk that was being given by the guy who started APRS at an AMSAT convention.  Went to that, and it turned out he had done the same thing, and had better maps than I had made, and already had it all working over ham radio.  So I missed the boat on that.
   But I still wanted to get maps that were better than the APRS maps, so I went to the USGS, and purchased world digital elevation data, and US vector line data for road maps.  After a couple months of work, I finally got the DEM data to produce world maps of shore lines, but I never did manage to create road maps out of the line data.  By the time I was even close, the data was obsolete, so I abandoned the project. 
   About a year ago I was thinking about playing with it again, and found that there were some applications that allowed you to port the location data to either Google Maps or Bing maps.  But after registering to get into the project, I found out that they had terminated the project, at least on a free basis. 

   I do use radio-transmitted GPS data from a dog collar that can be sent back to a receiver connected to my laptop, which will print locations out on a Garmin program with a Google Map screen, but that's not as much fun as doing it with my own programs.  Unfortunately the mapping software was way more complicated than I thought. 
 
    Anyway, I finally ordered one of the new Raspberry Pi model 2 B or whatever it's called, and I ordered a USB GPS, in hopes that I can figure out how to get the NMEA messages from it in Linux, and in hopes that there are some Linux mapping programs out there to put the position data on maps.  It will probably never amount to anything, but it should be fun. 
   I was also interested in the little video cameras for the RPi.  I just wish that they came with something longer than the 1 foot long ribbon cable, as I wanted to put the camera outside to watch animals while the RPi was inside. 
   Anyway, all sorts of neat things that you can do with the RPis.

Although I do dot dapple yet with the i2c stuff others like you may need it working also. I want to try to find what the issue is with the kernel upgrade. You should not have to use 2 pi's to accomplish what you want.

What type of errors are you getting?
Are they lib related like tune-s2 was trying to use old libs?
Are libs missing when you are compiling?

Could I have the source code to test here compiling?

I am glad you ordered rpi2b, You will be amazed how much better it is than the older pi's with the performance. If it was not for you I probably would not have any pi's at all. You got me hooked when we were getting UDL's kernel modules working on your older pi over a year ago. I ordered one after that but put it on the shelf after messing with it for a while and was dissapointed in the performance. It was decent for streaming but I did not care much for streaming when watch everything from my desktop.

When I saw what they had done with the newest model I ordered one. It sure has occupied my mind and time since I am retired.

Majortom has done a lot with the gps. He can probably help jumpstart you with you project.

wejones,

I have one of those Pi cameras, it's another project. I don't see why you can't hard wire LAN the camera into the house. Basically leave a weatherized rpi outside with camera;  supply power ac for the adapter or dc(there are people working on that).   Then find program or write code to stream camera to inside computer. I stream my rpi receivers into my LAN with updateDVB works slick, consumer wifi doesn't cut it though.

Getting programs onto the rpi is working great now. DarkSky has added capability to compile Qt programs. I do have to figure out how to get a link to the desktop.

I am going to order a GPS module, a few other things also.....[biggrin]

I think the kernel is out running the GPIO updates, and the i2c module upgrades. When you get down to hardware level's, the hardware addresses have to be considered so that might be part of it.
I have two older RPI's that take the full size SD's, I am going get them into action again.

If you want to play with code compilation go to this site:

https://github.com/DavidEGrayson/minimu9-ahrs/wiki

I got the code to compile and run on the 3.19 kernel, run into trouble on the second 4.0 and third 4.1 kernels; speaking of which it's nice to have them kernels on individual SD's which can be popped in and out and I don't have to unplug anything else on the rpi except unplugging power adapter from wall when I change the SD.

The site above has a link to the Ozzmaker site. He has software that compiles but doesn't seem to access my i2c module on any kernel. This is where hardware addressing comes into play.
The ozzmaker seems to be simpler code but ...

Don't spend to much time on it; like I said that project has a long way to go. It's a learning curve.

Thanks
Andy

You need to create a .desktop file and add it to your menu and then drag it to your desktop. I use alacarte to do it because I am lazy.

Open up a terminal and type:

alacarte

Click on where you want the new item to appear in the menu; I choose Other for updateDVB
Click on New Item and Enter the info and click on the icon area to add an icon you want and click ok:

1.png 

Then click on Restore System Configuration and then click on Close:

2.png 

Then go to where you added it in your Menu and drag it to your Desktop.
