Other Parts Discussed in Thread: TVP5146, TVP5150
Hello,I am using DM6437 development board.I use video_preview.pjt of DVSDK . but TI use A/D is TVP5146,and I use TVP5150,I don't know how to modify the code.please help.
the 5150 addr = 0xB8.
I blocked the code about 5146,and config the 5150's register.but I can't get the image.
