    I am designing a schematic with the DM3730 DSP. I may need to connect two cameras to my board. I see in the specifications that this is possible utilizing SCCB (serial camera control bus) on the I2C ports. I see a max data rate of 100kbits/s for the SCCB interface protocol. Is that accurate? I am...

    I am new to ARM and I am going to work on a new ARM development design using DM3730. Since my application is relatively small so I don't plan to use an OS. Then do I have to write the bootloader myself or I could get a bootloader code without OS. Also I will use Code Composer 4.x as SDK. Would the...

    Hi everyone, I'm new to the forum. We have our own custom DM3725 platform and we are developing a realtime audio application with very low latency requirements (musical instrument). So McBSP is directly driven by DSP that make most of the critical work. But we need also to have some audio work...

    Our board which uses DM3730 has LS-Research wireless module(Ti-Wifi 1271) and vendor we are working with says that in order to operate this module in the AP mode we probably better start using Linux kernel 3.x. On the hand we depend on TI DVSDK's codecs server package for (video encode/decode...

    Hi Rajesh, Ya you are right. CBP and CBC package provide support for CSI. Unfortunately, CUS package keeps those pins as Not-Connected. It is better to move on to the CSI supported package or else you can interface deserializer to the processor parallel interface pins. Regards, Sathya Kumar P
