PC-Basic TV FM SAA7130/TUA6030 Driver

I just bought this cheap PCI card (20 euros)... And i had some problems to make it working with Ubuntu 8.10

large_IMG_0157.JPG large_IMG_0151.JPG large_IMG_0176.JPG

This card doesn't have EEPROM, so no Subvendor PID/VID except from the well known Controller "Philips SAA7130"

The card is detected, we need to specify the parameters to get it working...

So i've take a look at the card PCB and opened the Tuner box... to understand the components and capabilities of the beast...

[31 Nov 2008]
Ok, i wrote the driver for this card, for the card itself (GPIOs configuration) and for the Tuner PLL... I am now able to watch 26 canals from the french analog Cable Numericable...

The second chip near the SAA is a microcontroller for the remote control...
Pin "I" of the "IGP" missing connector is connected to the IR connector, GP pins are Gnd and maybe the MCLR pin of PIC remote control µc..

To be continued... soon... Need to write IR Driver (GPIO thing), and FM Radio configuration

[2 Dec 2008]
Radio FM is working... very well :p !

After some research, i think the Remote Control Chip look like a 18pin 8bit PIC16F84 micro controller, VDD/VSS and XTAL pin's are at the right place... and IRDA signal come also on the unique Interrupt Pin (RB0)

I've connected the chip to a PIC programmer via ICSP (ICD2) ... but the chip seem's to be code-protected

Remote.JPG

If we assume the chip is a 16F84, RB0 is the Signal from IR Receiver, RB1 to RB7 are connected to SAA7130 GPIO 8 to 14.
GPIO 14 is the Key Press Event, it is set to zero when key is pressed.

For the last pin RA/GPIO 15 (which have a resistor pulled to VDD), it must be switched to 0 to enable IR listening...

So for the card configuration (in saa7134-cards.c)

[SAA7134_BOARD_PCBASIC_TV_FM] = {
/* Tanguy Pruvot (fr) <tanguy.pruvot on gmail.com> */
 .name           = "PC-Basic TVBasic-FM (saa7130)",
 .audio_clock    = 0x00187de7,
 .tuner_type     = TUNER_INFINEON_TUA6030, //TUNER_PHILIPS_FM1216ME_MK3,
 .radio_type     = TUNER_INFINEON_TUA6030, //TUNER_PHILIPS_FM1216ME_MK3,
 .tuner_addr     = 0x60, // i2c = 0xC0
 .radio_addr     = 0x60, // i2c = 0xC0
 .gpiomask       = 0x0108000,
 .inputs = {{
  .name = name_tv,
  .vmux = 3,
  .amux = LINE2,
  .tv   = 1,
 },{
  .name = name_comp1,
  .vmux = 1,
  .amux = LINE1,
 },{
  .name = name_svideo,
  .vmux = 8,
  .amux = LINE1,
 }},
 .radio = {
  .name = name_radio,
  .amux = LINE2,
 },
 .mute = {
  .name = name_mute,
  .amux = LINE1,
  .gpio = 0, //enable remote
 },
},

//... and at the end of the file... weird but needed

  case SAA7134_BOARD_PCBASIC_TV_FM:
    if (dev->i2c_client.addr != 0x60) {
      printk("%s: SAA7134_BOARD_PCBASIC_TV_FM tuner i2c client address set from 0x%x to 0x60\n",
                  dev->name, dev->i2c_client.addr);
      dev->i2c_client.addr = 0x60; //0xC0
    }
    break;
  } /* switch() */

Tuner box is from TCL, product page. (Thanks Hermann)

[5 December 2008]
Remote Control working !

saa7134-input.c

        case SAA7134_BOARD_PCBASIC_TV_FM:
                ir_codes     = ir_codes_manli;
                mask_keycode = 0x003f00;
                mask_keyup   = 0x004000;
                polling      = 50; // ms
                break;
        }

So, i compared the device settings with other cards... and i've seen a compatible card in the supported card list :
The Russian Behold TV 505FM (Card=126)

[linux-dvb] [TUA6030] From Hermann Pitton (.de) 3 Dec. 2008

These tuners have been seen at first on Hauppauge products as
replacement for the Philips FM1216ME/I H-3 (MK-3) and a member of the
video4linux-list in the UK had confirmation from Hauppauge's user
support there, that they are compatible with the prior tuner=38.

This was for a MFPE05-2. (PE = PAL/Europe)
http://tuner.tcl.com/English/html/enewsproopen.asp?proname=107&url=product
I think a MFPE05-3-E was reported on some device too.

Since then this tuner is mapped to tuner=38 in media/video/tveeprom.c
and is on several Hauppauge devices, but also on others. No complaints
so far.

The layout of the tuner PCB of your MFPE05-2-E and the FM1216ME MK3
seems to be identical. The most visible difference is, that the on your
tuner just unused tuner pins 7 and 8 are not present at the Philips at
all. Means 12 against 14 visible tuner pins according to your
photograph.

Else only the color of some of the coils differs and instead of TUA 6032
marked on the pll chip, on the pll used by Philips is only printed B2
and 230, but both have 38pins connected to the obviously same layout.

You might even have the same original EPCOS SAW filters, but your tuner
will not support NTSC, needs different filter equipment.
NTSC is covered by the MFNM05. (NM = NTSC N/M)
http://tuner.tcl.com/English/html/enewsproopen.asp?proname=108&url=product
This also causes the different bandswitch takeover frequencies.

On a first look at the main programming table all write and read bytes
are identical up to every single bit. You can find the datasheet of the
Philips FM1216ME MK3 we have these days at ivtvdriver.org.
http://dl.ivtvdriver.org/datasheets/tuners

If we find details not covered by tuner=38, you can get a new tuner
entry, but the patch must be against recent v4l-dvb. The radio should be
treated like on the other MK3 tuners in tuner-simple.c I guess.
IIRC, we have reports for radio working well with port1=1, inactive, FM
high sensitivity.

We would need a valid signed-off-by line from you as well.

Thanks, especially for the picture of the opened tuner. We did not have
any further details previously. Just testing results and the Hauppauge
hint.

Cheers,
Hermann
