Help My tuner
Hello,
I'm new to the forum and to this world, I'm really getting into the world of satellite TV.
I would like to try to create my own little receiver, so I built the MiniTiouner and word well, but now I would like to try to create one of my own based on the same Serit 4334L NIM.
The problem is that I could not find any information or datasheet on this NIM, I would need to have the complete registers map and maybe a guide on how to integrate the NIM.
Is there anyone who could help me?
thanks in advance

Re: Help My tuner
Nice try. All of this is covered by non-disclosure agreements.

Re: Help My tuner
So it is impossible for an amateur to use a NIM?
Re: Help My tuner
No, it is not impossible but if you want that data you need to sign an NDA with the company. What you are asking for sounds very much like someone trying to write their own software for it, rather than use the minitioune package developed by F6DZP. That's presumably why you ask for all registers. Manufacturers tend to be less keen to give out that information.

Re: Help My tuner
yes, I just did not think that for a product of this kind it was necessary to sign an NDA. It is not a military or strategic product, and we all have one in the home decoder, I thought it was much simpler.
Re: Help My tuner
There is one way to get around having an NDA and that is to look at the driver code for Linux.
They have virtually copied the reference implementation provided by the manufacturer ST micro.
The chips used in the NIM are the STV6120 receiver and STV0910ADB decoder.

Re: Help My tuner
Good point. Is there source code of just packaged binaries?

Re: Help My tuner
the one for the STV0910 is present, but I can not find the one for the STV6120. There are only for the 6110 and the 6111, @G4GUO do you know if they can be used as a reference also for the 6120?
@g0mjw if you are interested in writing a driver for this NIM, we can cooperate .

Re: Help My tuner
All the source code is there. In theory one could move the kernel driver into user space.
One will need to write code for the USB2 chip though to do the I2C.
If one knew what one was doing one could probably write a modified kernel driver for
the Minitiouner itself.
I use the term 'one' Mike as I know you are too busy to do any of that.

Re: Help My tuner
They are all very similar just a basic PLL and gain stages.federicomassimi wrote: ↑Tue Jul 24, 2018 7:30 amthe one for the STV0910 is present, but I can not find the one for the STV6120.
