RTOS/TIDEP-0088: Interfacing a camera with 66AK2Gx

Part Number: TIDEP-0088
Other Parts Discussed in Thread: TIDA-01454, , TMDSLCDK138

Tool/software: TI-RTOS

Hi,

I would like to add a video camera to the TIDEP-0088 reference design (EVMK2G and Circular Microphone Board TIDA-01454) so that I could process audio and video simultaneously. From what I understand EVMK2G does not include a video codec so I thought of using SPI. Will interfacing a camera via SPI be compatible with the TIDEP-0088 reference design connections between EVMK2G and the Microphone Board? Is there any TI EVM or reference design board I could use directly with EVMK2G for that purpose? Is SPI a good choice or should employ a different solution?

Thanks,

Adam

  • Hi Adam,
    We don't have any reference design for providing a video connection for the EVMK2G. I don't think the SPI interface will give you the bandwidth you need for streaming a video signal. While TI has other parts that provide a good path for video signal input, the K2G is not designed to easily connect to a camera. If you have a camera that can be accessed using one of the standard interfaces available, you will have to check the timing to see if the K2G can handle the bandwidth it requires.

  • Hello Bill,

    Thank you very much for your answer. I chose EVM2KG because I wanted to use Circular Microphone Board (TIDA-01454) and so start from a working reference design avoiding beginning from scratch. There is another reference design that uses CMB: http://www.ti.com/tool/TIDEP-0099, but the DSP board in it does not have a video input either. I have already investigated using TMDSLCDK138/6748 in this thread OMAP-L138: TIDA-01454 compatibility with TMDSLCDK138/6748 because it contains a video decoder. However this would require some modifications to the board. I want to avoid any hardware customisation as much as possible and directly start with developing the software. As for SPI, if the bandwidth starts to be a problem I can begin with a lower resolution camera or, in an extreme case, just take a photo periodically. What set of component would you suggest to accomplish the task of using the CMB and having a video input? I have worked with C6713 DSK for 15+ years, which is an extremely accomplished design by the way, but CCS is dropping support for older DSPs and this is also why I chose to escape forward and use some more modern DSP board for which I could expect future support.

    Thank you and best regards,

    Adam

  • Hi Adam,
    I don't have any suggestions for you concerning adding a camera input to the K2G. This was beyond the scope for the EVM and we haven't seen any designs using a camera input with that device. I can't point you to either a hardware solution or example software.
