I think there is no simple and good example for DM6437 EVM. I have searched all TI documents regarding to this module and I fund these:
1-Day workshop for DM6437 EVM.
Spraap3a
Beta_DM6437_Edge_Detection_Software_DM6437DemoImage_r1546
All the above files are full of unnecessary codes and functions which makes a beginner confused. A beginner needs a simple code to get a frame from input unit (VPFE & FVID), store it in DDR2, do a simple image processing function on it like IMG_erode_bin, and send out the frame (VPBE). A beginner needs a step by step tutorial like this:
1. Start a new project in CCS V3.3.
2. Create the main.c file with and includes necessaries libraries and header files like fvid_evmDM6437.h
3. small description for each line and further reading documents suggestion.
That's all
I think this tutorial helps developers to understand how to deal with this product much faster.
