cx88 driver: Help needed to add radio support on Leadtek WINFAST DTV 2000 H (version J)

Hello list,

I've started the task to add support of the board mentionned above.

So far I've got analog TV, Composite and Svideo inputs working OK with IR as well.

Unfortunately, my area does not have DVB-T yet, but from the scans I've made, I'm confident DVB support is on good tracks.

Nevertheless, I cannot achieve to have the radio input working.

The gpio values were captured with regspy on a working windows installation.

Here are my additions in cx88-cards.c:

Unfortunately, my area does not have DVB-T yet, but from the scans I've made, I'm confident DVB support is on good tracks.

Nevertheless, I cannot achieve to have the radio input working.

The gpio values were captured with regspy on a working windows installation.

With the ivtv driver, I helped debug the LG TAPE-H series tuner on the PVR-150MCE not demodulating FM radio. (Hans actually got the fix put in.) The problem turned out to be the incorrect "bandswitch byte" being set in tuner-simple.c. AFAICT, the gpio values for the CX23416 aren't used to set the FM radio on the PVR-150MCE.

There is a "bandswitch byte" in the synthesizer/1st mixer chip (probably a tua603x chip) in the tuner that controls some gpio pins. These gpio pins setup the tuner's preselector by switching in the proper bandpass filter for the Low VHF, FM, High-VHF, or UHF bands

For the FM1216ME_MK3 tuner (not the FMD1216ME_MK3) this bandswitch byte needs to be set to 0x98 for FM stereo or 0x9a for FM mono.

I notice in tuner-simple.c:simple_radio_bandswitch(), that for both the FM1216ME_MK3 and the FMD1216ME_MK3, the bandswitch byte for FM is coded as 0x19. This is a bit-reversal of 0x98. This seems wrong according to the FM1216ME_MK3 tuner datasheet here:

http://dl.ivtvdriver.org/datasheets/tuners/FM1216ME_MK3.pdf

I can't find the FMD1216ME_MK3 datasheet with some quick google searches. I cannot conclusively say the coded bandswitch byte of 0x19 is wrong for the FMD1216ME_MK3, but I think it's worth some investigation/experimentation.

You might also want to check/fix the tuner-simple.c:tuner_stereo() function while you're at it.

Good luck,
Andy

Correction, I read the datasheet wrong. It should be 0x19 or 0x59. I reversed the bits. (The data sheet had the LSB in the left column of the table and the MSB in the right column of the table for some reason.)

http://dl.ivtvdriver.org/datasheets/tuners/FM1216ME_MK3.pdf

Again correction: I was the one who was wrong. The code for the FM1216ME_MK3 bandswitch to radio matches the datasheet.

I can't find the FMD1216ME_MK3 datasheet with some quick google searches. I cannot conclusively say the coded bandswitch byte of 0x19 is wrong for the FMD1216ME_MK3, but I think it's worth some investigation/experimentation.

This I still think is worth verification for the FMD1216ME_MK3. But given that the Phillips designs and the LG rebranded Phillips designs all seem to follow this pattern, I suspect it is correct.

Quoted 1 line

You might also want to check/fix the tuner-simple.c:tuner_stereo() function while you're at it.

The FMD1216ME_MK3 is missing from this function. Once you can here stereo and mono stations, it is worth checking if this function is correct for the FMD1216ME_MK3

Hello list,

Unfortunately, my area does not have DVB-T yet, but from the scans I've made, I'm confident DVB support is on good tracks.

Nevertheless, I cannot achieve to have the radio input working.

The gpio values were captured with regspy on a working windows installation.

With the ivtv driver, I helped debug the LG TAPE-H series tuner on the PVR-150MCE not demodulating FM radio. (Hans actually got the fix put in.) The problem turned out to be the incorrect "bandswitch byte" being set in tuner-simple.c. AFAICT, the gpio values for the CX23416 aren't used to set the FM radio on the PVR-150MCE.

There is a "bandswitch byte" in the synthesizer/1st mixer chip (probably a tua603x chip) in the tuner that controls some gpio pins. These gpio pins setup the tuner's preselector by switching in the proper bandpass filter for the Low VHF, FM, High-VHF, or UHF bands

For the FM1216ME_MK3 tuner (not the FMD1216ME_MK3) this bandswitch byte needs to be set to 0x98 for FM stereo or 0x9a for FM mono.

I notice in tuner-simple.c:simple_radio_bandswitch(), that for both the FM1216ME_MK3 and the FMD1216ME_MK3, the bandswitch byte for FM is coded as 0x19. This is a bit-reversal of 0x98. This seems wrong according to the FM1216ME_MK3 tuner datasheet here:

Quoted 6 lines

http://dl.ivtvdriver.org/datasheets/tuners/FM1216ME_MK3.pdf

I can't find the FMD1216ME_MK3 datasheet with some quick google searches. I cannot conclusively say the coded bandswitch byte of 0x19 is wrong for the FMD1261ME_MK3, but I think it's worth some investigation/experimentation.

Hi,

it is, we were only hackers!

And there is no substitution for it.

The radio stereo hack was specific for the FM1216ME/I H-3 (MK3) and the FMD1216ME/I H-3 (MK-3) never could utilize that bit reading out the stereo status for FM ...

Cheers,
Hermann

Hi Andre,

guess we could need someone to tell about SECAM_L NICAM stereo on latest, you might have had a reason to send your current saa7134 patch for 2.6.24 only, eventually?

For the radio, see my previous posts to Andy.

Radio on the FMD1216ME/I MK3 is not perfect anyway, on other stuff it might also only be the best hack around then, but some still claim new hardware doesn't exist ...

Your Items saa7134 patch is not unnoticed, but I would have a lot of questions and maybe Hartmut, Nickolay and everybody still interested too.

Try to send it again, read about new cards on the v4l-wiki and about patches on a recent v4l-dvb mercurial, we don't invent the rules ...

As a hint, you might have much better chances for somebody to start looking at it, if you split the card and remote addition in two separate patches.

Cheers,
Hermann

One is missing here.

You might have the newer FMD1216MEX, Steve mentioned sometime previously, it might be slightly different for the radio support.

I do know exactly nothing about it.

From the driver's inf file I read:

[LR6F2B.AddReg] HKR,"DriverData","FMD1216MEX",0x0010001, 0x01, 0x00, 0x00, 0x00

This probably means you guessed right.

That's a step forward, isn't it?

Too bad you cannot say more.

I'll keep you posted.

Rgards,
