Ticket Name: TDA2EVM5777: how to add new sensor to TDA2

Query Text:
Part Number: TDA2EVM5777 Other Parts Discussed in Thread: TDA2, TDA2PXEVM Dear TI I would like to include in new sensor to the TDA2. How or where can i create it to do that?

Responses:
Hi Wilson, You can check this Application Note: processors.wiki.ti.com/.../PDK_Application_Notes_Video_Driver_Porting and also Chapter 3 in "vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_UserGuide_ISS_SensorFrameWork.pdf" Regards, Yordan

Hi Yordan Can i ask what is ISS stands for?

Hi Wilson, It's Imaging Sub-System. Regards, Yordan

Hi Yordan I wouls like to ask what is the follow abbreviation DCC H3A GLBCE AEWB Also is it a must for me to code them? On top of this ISS is it suitable to run in TAD2EVM5777 if i am going to add this new sensor? From the VisionSDK it seem like its for the TDA3xxEVm and TDA2PxEVM instead.

Hi Wilson, These components are used in the ISS usecase, ISS is present in TDA3x and TDA2Px It is not supported in TDA2Ex. DCC = Dynamic Camera Configuration H3A = Statistics generation module for AE and AWB. GLBCE = Global and Local Contrast and brightness Enhancement AEWB = Auto Exposure and White Balance Rgds, Brijesh

Hi Brijesh So if that the case how can i should i go about for the a new sensor then?

Wilson, You could capture from RAW Bayer data from the new sensor on TDA2x/TDA2Ex, but since there is no ISS, you will require SW solution to process and convert RAW data into YUV. The other way is, you could use YUV sensor. Rgds, Brijesh

The Brijesh in other words can i say there is no algo in the SDK to help us to process this Ray Bayer. I have to code it myself.

yes

Dear Brijesh I notice there are 2 type of yuv which format i should be convering the bayer to?

Wilson, DSS supports both YUV420 (Semi-planar) and YUV422 (Interleaved) data format. So if you could convert RAW to one of these data format, dss will be able to display it. Rgds, Brijesh
