H i ,everyone.
W hen I debug the Generic YUV mode of DM355 VPFE,I find a problem.
The image input to dm355 is produced By FPGA(it get the image from the VGA signal of PC via a video decoder),the PCLK is 65MHz.CCD0~CCD7 is Y,
and CCD8~CCD15 is Cb/Cr.
T he right image is like this:
B ut the image which is get by the application of the DM355 is like this:
Y ou can see the frame of the window have some protraction .
I n the beginning I doubt that the waveform of the FPGA is wrong ,but if I make the Cb/Cr 0x80
( i.e. CCD15~CCD8 is always 1000 0000B,the image is gray )
and change nothing else,the image get by the application of the DM355 have no protraction .
it is like this(I think it can show that the waveform of the FPGA is right):
T hen I make the Y 0x80( i.e. CCD7~CCD0 is always 1000 0000B ,
CCD15~CCD8 is the Cb/Cr of the image)and change nothing else,
the image also have no protraction .it is like this:
I think there is something wrong in the matching between dm355 and the FPGA .
this is my configuration of the dm355 vpfe register, help me please,thanks!!!!!
