D3-3P-TDA3X-SK: TDA3X Starter Kit Adding New Sensor to ISS Framework

D3-3P-TDA3X-SK: D3-3P-TDA3X-SK:

Part Number: D3-3P-TDA3X-SK


Hi team,

I am currently in the process of familiarizing myself with the TDA3 platform and aiming to integrate a new sensor into the capture sources. Specifically, I intend to use the camera based of onsemi sensor to stream video and display it on an HDMI screen.

In my exploration of the SDK documentation, I've identified the ISS framework as the primary means to add a new sensor. However, I would appreciate clarification on whether alternative methods exist for sensor integration within the SDK.

I possess the datasheet provided by the sensor manufacturer (in my case Onsemi), which outlines technical specifications and interface details. Could you please advise if any additional documentation or information from the manufacturer is necessary for successful integration?

Additionally, I've observed limited resources pertaining to the process of adding a new sensor to the SDK. Is this scarcity due to any restrictions imposed by TI on the types of sensors permitted for integration?

Furthermore, I seek clarification on whether the SDK permits the addition of new sensors or if it exclusively supports those pre-listed in the appimage accompanying the starter kit.

Lastly, would it be possible to obtain comprehensive guidance, such as a document or instructional video, outlining the steps for integrating a new sensor into the SDK? Such resources would greatly benefit newcomers like myself in navigating this process effectively.

I eagerly await your response and appreciate your assistance in this matter.

Warm regards,

Rejoy

    Hi Rejoy,

    TDA3x supports two input interfaces for interfacing with camera, ie DPI input and CSI input. Which input interface that you are planning to use?

    Hi Brijesh,

    Thank you for your prompt response. If my understanding is correct, I will be utilizing the CSI input. The camera designated for testing is an automotive-grade unit, accompanied by an FPDlink serializer board connected via a Fakra-type connector.

    Regards,

    Hi Rejoy,

    Since you are using CSI input, most likely you are interested in ISS based usecase, is it correct?

    I think in vision sdk, there is an imaging layer, where you can add new sensor. If i remember, there was an application note explaining how to add a new sensor in vision sdk

    Yes i am trying to use the ISS usecase

    "I'm currently exploring the Image Sensor Subsystem (ISS) use case and have come across the manual located at "vision_sdk/docs/FeatureSpecificUserGuides/VisionSDK_UserGuide_ISS_SensorFramework.pdf". However, I'm still unclear about the process for adding a new sensor. If there's a different application note that provides more clarity on this, could you please share it with me?

    Additionally, I understand that the camera module I'm working with includes a 953 serializer. Are there any additional settings I need to configure in order to properly initialize the camera through the serializer?

    I apologize if these questions seem basic, as I'm new to this technology and still getting acquainted with its intricacies.

    Hi Rejoy,

    I think there was an application note explaining how to add new sensor in the imaging framework somewhere in the vision sdk documentation. Can you please refer to it? 

    In general SERDES settings need to be taken care in the sensor itself, typically in config or in stream on callback in the sensor.

    Hi Brijesh,

    Is this the manual you are referring to ? I couldn't find any other application notes.


    You said the SERDES settings have to the taken care in the sensor, out of all the sensor drivers available in the SDK(snapshot given below) which one will be good one for me to refer considering i have a on semi sensor with 953 serializer.


    Also is there any courses or training program i can sign up with TI to learn about this?

    Thank you,

    Rejoy

    Hi Rejoy,

    Can you please refer to vision_sdk\apps\src\rtos\iss\src\sensor\iss_sensor_tda3xx.c file on how to add SERDES and sensor configuration? 

    Regards,

    Okay I will refer the file you mentioned , but are you saying this is the only file i have to modify to add a new sensor to the TDA3. Also can you please point me to the application note you mentioned in your earlier replies..

    Hi Rejoy,

    I am unable to find it, so can you please refer to this file? For SERDES, yes, please refer to this file and for sensors, you can refer to one of existing sensor implementation.
