Tuning a transponder for Signal Info Level and Quality...

Postby yeyotheiron » Fri Jan 11, 2008 7:47 am

With this code can not get the transponder is tune properly. Even when the program
started without selecting a channel previously.

Attempt a module that speak the values of quality and level of the signal.

var
ASatList: TSatList;
ASglInfo: TSignalInfo;
Quality,
Level: String;

procedure TFormMain.FormCreate(Sender: TObject);
...
ASglInfo.dwSize:= SizeOf(TSignalInfo);
...
end;

procedure TFormMain.cb_SatListChange(Sender: TObject);
...
ATpList.wSatPos:= ASatList.Sats[cb_SatList.ItemIndex].wPos;
SendMessage(DDHwnd, WM_MODULE_MSG, DDMODAPI_GET_TP_LIST, Integer(@ATpList));
...
end;

procedure TFormMain.pbbtn_TunerClick(Sender: TObject);
var
_SetTunerParams: TSetTunerParams;
begin
_SetTunerParams.wSatPos:= ASatList.Sats[cb_SatList.ItemIndex].wPos;
_SetTunerParams.tpi.dwSize:= SizeOf(TSetTunerParams);
_SetTunerParams.tpi.dwModulation:= ATpList.TPs[lv_Tps.Selected.Index].dwModulation;
_SetTunerParams.tpi.dwFreq:= ATpList.TPs[lv_Tps.Selected.Index].dwFreq;
_SetTunerParams.tpi.Pol:= ATpList.TPs[lv_Tps.Selected.Index].Pol;
_SetTunerParams.tpi.dwSr:= ATpList.TPs[lv_Tps.Selected.Index].dwSr;
_SetTunerParams.tpi.dwLOF:= ATpList.TPs[lv_Tps.Selected.Index].dwLOF;
_SetTunerParams.tpi.dwLnbKHz:= ATpList.TPs[lv_Tps.Selected.Index].dwLnbKHz;
_SetTunerParams.tpi.dwInversion:= ATpList.TPs[lv_Tps.Selected.Index].dwInversion;
_SetTunerParams.tpi.dwFec:= ATpList.TPs[lv_Tps.Selected.Index].dwFec;

SendMessage(DDHwnd, WM_MODULE_MSG, DDMODAPI_SET_TUNER, Integer(@_SetTunerParams));
end;

procedure TFormMain.t_SignalsTimer(Sender: TObject);
var
_TransponderInfo: TTransponderInfo;
begin
t_Signals.Enabled:= False;

_TransponderInfo.dwSize:= SizeOf(TTransponderInfo);
SendMessage(DDHwnd, WM_MODULE_MSG, DDMODAPI_GET_TRANSPONDER_INFO, Integer(@_TransponderInfo));
with _TransponderInfo do
begin
l_Info1.Caption:= Format('%d, %d, %d', [dwFreq, Pol, dwLnbKHz]);
l_Info2.Caption:= Format('M:%d, Sr:%d, LOF:%d, I:%d, F:%d', [dwModulation, dwSr, dwLOF, dwInversion, dwFec]);
end;

SendMessage(DDHwnd, WM_MODULE_MSG, DDMODAPI_GET_SIGNALINFO, Integer(@ASglInfo));
Quality:= IntToStr(ASglInfo.Quality);
l_Quality.Caption:= Quality + '%';
pb_Quality.Position:= ASglInfo.Quality;
Level:= IntToStr(ASglInfo.Level);
l_Level.Caption:= Level + '%';
pb_Level.Position:= ASglInfo.Level;
l_Info3.Caption:= IntToStr(ASglInfo.Locked);

t_Signals.Enabled:= True;
end;


Reviewing the LOG file the application note that does the following:

...

But when you select a channel by tuning the transponder adds some of the Diseqc:

Is it necessary to tune transponder with DDMODAPI_SET_TUNER some other API?

Thanks, excuse my English.

there was something wrong in SET_TUNER api command. I have tried to fix it . please test with the following patch.

Right now this patch allows tune.

The signal information, Quality and Level, also reflect tuning.

But, later:

SendMessage(DDHwnd, WM_MODULE_MSG, DDMODAPI_GET_TRANSPONDER_INFO, Integer(@_TransponderInfo));

It does not reflect the new Transponder tuned.

Thanks, excuse my English.

Here is the idea, but as you can see is not yet finished.

yTpSpeak_v1.0.2.101_Alpha.rar file deleted.

The source code is no big deal. I also add it.

Thanks, excuse my English.

looking nice.

here is another patch, which should work better:

www.dvbdream.org/patches/dd_patch_080116.rar

the problem is that some TV cards dont support getting the current tp state. (current frequency) , so this API will return the latest values sent.

The snapshot function are not working in this nice MOD.

Thanks for share the the MOD with DD users

i change the ini list with feedfreq and he scan them for my excelent tool for feedhunt when you use it as scanner great.

The snapshot option is not developed, yet. Depends "Levels" works as I hope. Soon...

I will try this patch dd_patch_080116.rar today.

I do not know. Already understand.

Perhaps a idea to switch to a TP if you see that there is a signal.

And DD switch to that TP also.

Here is a better idea. Of course it is necessary dd_patch_080116.rar, with this version work as expected everything.

yTpSpeak_v1.0.2.268_Beta.rar file deleted.

Thanks rel, DD is great, tremendous job.

only 4 downloads for this great tool????
It must be standart in DD.

First impression great again today 21 Jan some (3)feedhunters are going to test it more here .


When Q = 100 left side of Q are out of window
When Q = 100 in list he shows as 1...

dvbdream give's window with "listindex out of bounds (8)" scanning stops
in line in INI file are 11914,H,27500 9A NBC-QPSK remove 9A etc and gone running no more out of bounds

I wonder if that error happened on one of DD v1.4i's dialogs ? (since you were testing it Snuffer, happened on channel properties etc ?)

there will be one more modulation contant (NBC) in upcoming v1.4i:

MOD_DVBS_QPSK = 0;
MOD_DVBS_8PSK = 1; // DVB-S2 8PSK
MOD_DVBS_16APSK = 2;
MOD_DVBS_32APSK = 3;
MOD_TURBO_QPSK = 4; // Dish Network QPSK (Turbo)
MOD_TURBO_8PSK = 5; // Dish Network 8PSK (Turbo)
MOD_DVBS_NBC_QPSK = 6; // DVB-S2 QPSK (NBC)

Fix.
It was funny error of 100%, with my equipment and my conditions are impossible to obtain these levels.

>rel
>MOD_DVBS_NBC_QPSK = 6; // DVB-S2 QPSK (NBC)

Add.

Thank you both.

Here is other version, I think, better.
