Hi All, I have been trying to display decoded video using the DDK libraries on DM642. The output of the decoder is YUV 4:2:0 format. However for displaying it correctly on the VGA Monitor, I need to convert it to RGB for proper color. The documentation seems to suggest t

Hi Jeff, > Why not use TI's existing driver? And call it from your DLL or driver? Can you tell me where to get this TI driver? When it comes to PC drivers and libraries to access DM642 from a Windows/Linux PC, I cannot find a lot at TI. There is a little bit available together with the EVM boards, but this libs can only be used together with the EVM boards... Could you recommend me source

I have run into an issue on one of my boards (custom) where the DM642 will assert multiple reads without dropping any of the CEn signals. This happens when the DSP supposedly reads from CE3. I have tried both a mem-copy and EDMA with the same results on this particular board. Other boards work fine, but this one does not seem to drop the CEn signal. It does on test code, but not my "full up"...

Hi all, I am trying to configure saa7115 digital video decoder in order to use its scaling features.Though i have changed the register settings in _saa7115.c present in vport project that comes with dm642 board but i am not able to get any change in the final display after rebuilding the whole vport library once again. I think i am missing somet

Hi, I saw this old thread on a forum and wanted to ask you if you resolved the problem you were having with the code starting to execute? I have a similar problem myself with the DM642, except that I am using the HPI interface to load my software on a bespoke PCB design. The steps I follow are: 1. Take the processor out of reset and into host boot mode. 2. Configure the EMIF. 3. Load t...

Hi, I would like to use a square root routine for fixed point number in DM642 platform. Is there some optimized library for this operation (I wasn't able to find it in fast rts)? Or can you provide some link to algorithm usefuls for this kind of operation? Many thanks

Hi there: Recently I have worked on a project which uses FX2 slave FIFO from DM642. FX2 is Cypress CY7C68013(56 pin). Since I have never done this before, I nearly have no idea where to make this device driver to FX2 from DM642. Is there someone who had been familiar with it? Please give me some pieces of advice or references. Thanks in advance!

Hi, I'm just starting working with a DM642. I've developed an algorithm, which runs nice and fast (1/30 sec). However, the video capture and output seems to be slowing the system down enormously. To capture/display the video, I'm using the code from

Hi, all, I want to capture CIF size video in DM642 board. According to spru615.pdf, I set EVMDM642_vCapParamsChan2.scale = VPORT_SCALING_ENABLE to open 1/2 scaling mode to reduce the horizontal resolution. But I found some black spots appeared at the borders of the bright objects in the captured pictures. Who knows the cause of the problems and how

Hi all, If anyone knows of any manual(except spru629D and apra918a) or TI document which explains the interaction between board specific part and generic part on DM642 platform in amore general way. Sone of the questions for which i am trying to find out answers are: 1.What is the relation between the external clock, crystal oscillator and pixel

Hi all, I am trying to configure saa7105 Digital encoder chip which is present on the DM642 evmboard to use its horizontal and vertical scaler features.My purpose is to upscale CIF image to 704*576 size. In the register settings of saa7105 there is one parameter called YUpscaleActive.I made it 1 and on the final display i am getting a parallelogram sh

Hi Everybody, I need your help to understand if I can do this project. (I'm a beginner in streaming and in network applications using DSP). I have ported an H263 code over DSP DM642 (Ateme board DMEK642 + camera connected to the board + Code Composer Studio 2.21) and now I would like to stream it over IP to show the video in a player like QickTime or
