  • RE: problem with bfin_video_capture

    uclinux have full support for bf533 Ez Kit adv7183, adv7171, ad1836 and usb lan extender?

    and also how many analog input i can use with adv7183? can bf 533 support (it perfomance) several cams?

  • RE: V4l2 video0

    ezkit.c is a board file where you pass some board specific parameters to the driver. adv7183.c is the real driver but it is a decoder driver. vs6624.c is a sensor driver which is similar to ov sensors.

    adv7183_input is the input array adv7183 can support…

  • RE: Help with multiple video inputs


    Concernig your citation: "this function does not exist in the BF533 board."

    The PF0 and PF1 pins are connected to ADV7183 sdata and sclock pins. So you can send commads to the adv7183.

    Bf533 does not have a I2C channel. So you have to…

  • ADV7183B & BF561 connect?

    I'm using BF561 + ADV7183B. How to connect ADV7183B's FIELD pin(PIN-80)?

    Ref the BF561-EZKIT BF561's PF3 connect with ADV7183B's FIELD pin. But in the example code(VisualDSP5.0\blackfin\examples\ADSP-BF561 EZKIT Lite\Video Input-Output (C)) PF3…

    As you might be aware, GPIO based bit banging driver is already available with Linux. They also have video for linux, that includes the ADV7183 driver.

     Please refer this adv7180.C/adv7183.C.



  • RE: No image??

    Hi Andy,

    ADV7183 datasheet seem to mention about 0x04 as the INSEL[3:0] value for AIN5. You can also see similar setting used in I2C Programming Example in this datasheet. Other than that, ensure that the device address is always acknowledged. Perhaps…

  • RE: ADV7183B not responding to I2C (NACK)

    Hi Matt,

    I know the ADV7183 is an older product, but it's what we currently have available as a testbench. I do have the EVAL-ADV7180-32EBZ board, however, as there is no easy way to put an interface between the decoder and encoder chips, I'm working…

  • RE: Video Inputs AVIN4



    Your understanding is correct.


    In this Video Input project, processor resets the ADV7183 Decoder chip in the 'Init_ADV' routine and it does not further programs this chip.

    So, ADV7183 works with it's default settings and decodes…
