question about DM368

is it true that to be able to get white balance/auto exposure on the DM368 you have to buy a library from appro or ridgerun?

does TI provide any white balance/ auto exposure support for the DM368?

    Andre,

    Are you using the IPNC reference design from Appro?

    The reference design includes the Appro 2A (AWB/AE) library and as well as a TI AWB library which can be used. But the source code for AWB library is not shared.

    Regards

    I capturing video with the MT9P031 and the DM368 I'm not using the reference design from appro, but the image is overexposed, you told me to use to the H3A but in the manual it says it's not supported,  so how can I get a clear image? I got the development kit from TI and I have not got much support for it,

    Regards,

    Andre,

    We ship the AWB/AE implementation example with the Appro reference design kit (software). 

    I think the support is not included in TI development kit, I am not very sure of this. Do you the TRM for DM368, the H3A module is included part of the VPFE block in the chip. I beleive you could use the H3A block and make your own algorithm.

    Rajat can you please post documentation of how to get the autowhite balance working the DM368 and the MT9P031 camera sensor, if you look on page 123 on this guide  http://www.ti.com/lit/ds/symlink/tms320dm368.pdf it says is not supported, is that an error on the guide?

    also can you please post documentation of how to do this, how do I use the aew_example.c with the camera sensor? I could not find any guide on this.

    Regards,

    Andre

    Andre,

    I have no experience on the standard evm development kit software. I work on the IPcam reference design with appro and in that we do support the 3A engine drivers.

    Will you be able to check with the local FAE at your end on difference between your platform and the DM36x soc used in Appro IPNC?

    Regards

    I dont know what FAE means, but the DM368 guide it says is not supported in the hardware,  so appro provides a solution in software, I called TI and they told me you are the expert and that you would know about this. :(

    do you know how can I get in contact with someone who can help me with documentation of how to use the DM368 chip and the MT9P031 to get a clear image?

    Regards,

    Hi Andre,

    For the H3A support you will need to get the soc part and software from IP camera reference design. The H3A support is available in hardware and the corresponding drivers and 2A libraries will be included.

    We do not support the H3A solution in the DM368 dvsdk / evm (general market) platforms, thus the same limitation is mentioned in the documentation that you have. 

    Therefore, I suggested you earlier to check with a local TI field application engineer (FAE) on H3A supported parts and relevant documentation. To know about the FAE you need to contact the nearest TI sales office in your region.

    Regards,

    Rajat
