Hello,
I have changed the firmware provided in AN75779.zip to meet the requirement of my own sensor with the following features:
1.16-bit synchronous parallel data interface
2.16 bits per pixel
3.YUY2 color space
4.1920*1080 pixel resolution
5.30 frames per second
6.Active high line valid signals,Active low frame valid signal.
7.Positive clock edge polarity
For 16-bit synchronous parallel data interface, I go to the Interface Definition tab in GPIF II Designer and choose the 16 Bit option for Data Bus Width, then i go to the state machine tab, change the counter limit value of LD_DATA_COUNT and LD_ADDR_COUNT to 8183.Finally, i update the cyfxgpif2config.h in original firmware project,andmake sure the iomatrix configuration in the firmware has the isDQ32Bit parameter set to CyFalse.
For 1920*1080 pixel resolution, I change the related content of descriptors as follow,
/* Class specific Uncompressed VS format descriptor */
0x10, /* X dimension of the picture aspect ratio; Non-interlaced */
0x09, /* Y dimension of the pictuer aspect ratio:Non-interlaced */
/* Class specific Uncompressed VS frame descriptor */
0x80, 0x07, /* Width in pixel */
0x38, 0x04, /* Height in pixel */
and changed the probe control setting.
My sensor can output the data.After all, I build the firmware project and download the .img file into FX3 and preview real-time video use software like AMCap/VirtualDub, the system could work, the video is abnormal,the image is attached,it like the U data and V data in the video are inverse. And the AMCap/VirtualDub could not read the video information like resolution.
I don't knoe what I should modify.
I hope someone could help me, Thank you.
