Hello Everyone,
I have the *DM6437 EVM* & Started working on the same,Tried Audio examples and some modifications and board is working fine for audio processing.
I used matlab Simulink to generate Code for the board all the way for both Audio and Video Processing.
I am using a Camera from CP PLUS CP BY_48,it supports both PAL:537Hx597V, NTSC:537Hx505V and a TFT 7.5'' display with support of PAL/NTSC/SECAM.
The camera module is connected to the Video In of EVM DM6437 and Display i have connected to DAC B output.
Also i know that the DM6437 EVM Supports both PAL/NTSC formats ,So i tried to do a simple Video loopback using Simulink Model (Video Capture block followed by Video Display Block) ,I set the Settings in Capture block for PAL,Composite video and 1/25 as Sampling rate,Also the settings for Video Display Block as video position [0,0,720, 480],PAL,Composite video.
After building the model and the code generated ,was uploaded to DM6437 using CCsV5 ,and the program was working fine,video input was displayed at the board video output.
I tried to modify the Setting of blocks for NTSC format,the Video Out displays a pink Screen on display.Even changing the on board jumper JP1 for NTSC format.
Also i tried some other video processing examples like Edge detection ,Barcode Recognition etc with PAL settings,they worked Successfully but with NTSC the same results(pink display).
I have attached the images for both PAL and NTSC outputs .
Do i need to do some other settings for NTSC format to be displayed?
