Revision as of 19:37, 22 July 2010
A Small USB based analogue capture device using EM2860 and Xceive xc2028 chip Tuner.
It is currently not supported under Linux.
Overview/Features
- It has Television and S-Video inputs via a Two separate 3.5mm tail cables
- It falls under V4L's "Em28xx devices" category (being based upon an EM2860 usb bridge)
Components Used
- Empia EM2860 (USB video bridge)
- Empia EMP202 (AC'97 audio processor)
- NXP/Philips SAA7113 (video decoder)
- Xceive XC2028ACQ (Analog chip tuner)
- 24C04 (EEPROM)
- HCF4052 (4-channel Analog multiplexer)
Other Pictures
Current Status
- Currently it works after patching the v4l-dvb.
- Need to test the sound and Composite inputs.
- Will release the patch soon.
- I need help on releasing this as a Patch upstream.
- Also I need help to upload some real pictures of the device into this Wiki( I can't figure it out till now(BAD ME).
- Anybody interested can contact me jeevas.v AT gmail.com
To make it work
I have done these changes to make it work.
- 1. extract the Xcieve firmware for xc2028 and copy to /lib/firmware as mentioned in the em28xx page.
- 2. extract the latest v4l-dvb source as mentioned in the em28xx page.
- 3. go to v4l-dvb/linux/media/video/em28xx folder.
- 4. edit em28xx.h file and add the device:
. . #define EM2870_BOARD_REDDO_DVB_C_USB_BOX 73 #define EM2800_BOARD_VC211A 74 #define EM2882_BOARD_DIKOM_DK300 75 #define EM2860_BOARD_GADMEI_UTV380 76 . .
- 5 edit em28xx-cards.c and add the card in card definitions
.
.
.
[EM2860_BOARD_GADMEI_UTV380] = {
.name = "Gadmei UTV380",
.tuner_type = TUNER_XC2028,
.tuner_gpio = default_tuner_gpio,
.has_dvb = 0,
.decoder = EM28XX_SAA711X,
.input = { {
.type = EM28XX_VMUX_TELEVISION,
.vmux = SAA7115_COMPOSITE2,
.amux = EM28XX_AMUX_VIDEO,
}, {
.type = EM28XX_VMUX_COMPOSITE1,
.vmux = SAA7115_COMPOSITE0,
.amux = EM28XX_AMUX_LINE_IN,
} }
},
.
.
.
And also add the card's usb id in the list if it is not already there.
.
.
{ USB_DEVICE(0xeb1a, 0x50a3),
.driver_info = EM2860_BOARD_GADMEI_UTV380 },
.
.
- 6. Edit em28xx-core.c and make sure that the AC97 audio processor is properly detected. In this case I have to add one more vendor based on the dmesg output.
. .
/* Try to identify what audio processor we have */ if (((vid == 0xffffffff)||(vid == 0x83847650)) && (feat == 0x6a90)) dev->audio_mode.ac97 = EM28XX_AC97_EM202; else if ((vid >> 8) == 0x838476) dev->audio_mode.ac97 = EM28XX_AC97_SIGMATEL; . .
- 7. Then execute the following commands to build and install the kernel modules.
sudo make distclean sudo make menuconfig (Due to some error I have to disable one of the modules in the list to get past the compilation). sudo make sudo make install
- 8. After this restart your machine, plugin your device and start your favourite tv app and enjoy.
