Hi experts.
I have an question about BT656 capturing. Currently,we fails to capture images. there is no interrupt for capture completion.
BTW, input resolution from a camera is 160x240@60fps(8bit, so Y/C muxed, 27Mhz Pixelclock) not NTSC.
I wonder if these format can be captured on C6748. It's BT format including EAV/SAV.
Please see the image below. Following waveform is repeated 60times per second.
We modified facetect.c in c6sdk_02_00_00_00 and tried to interpret the video format as 160x480@30fps(interleaved).
Soimething strange is EAV2SAV is 1389, oddnumber. but it should be even number. Can this cause a problem?
#define STW_EAV2SAV 1389
#define STW_SAV2EAV 320
#define STW_L1 1
#define STW_L2 1
#define STW_L3 (STW_L2+1) // 2
#define STW_L4 (STW_L2+240) // 241
#define STW_L5 (STW_L4+1) // 242
#define STW_L6 (STW_L4+21) // 262
#define STW_L7 (STW_L6+1) // 263
#define STW_L8 (STW_L6+1) // 263
#define STW_L9 (STW_L8+1) // 264
#define STW_L10 (STW_L8+240) // 503
#define STW_L11 (STW_L10+1) // 504
#define STW_L12 (STW_L10+21) // 524.
#define CAPTURE_IMAGE_WIDTH (160)
#define CAPTURE_IMAGE_HEIGHT (240x2)
C0CFG : FieldFrame = 0, field-based
VANC = 0, disable
HANC = 0, disable
INTFRAME = 2, top and bottom
YCMUX = 1, Y/C muxed.
CAPMODE = 0, BT video
C0IMGOFFSET = 160
Thanks,
Devin
