Discussion - Software / FT602 video encoding type and bus frame questions
« on: February 17, 2023, 06:32:10 AM »
Hi all,
Just wanted to confirm FT602, the spec says:
Can I confirm it also supports uncompressed gray, please?
We have a 1440x512 gray streaming into the chip, the requirement says:
Is the below correct?
<0000_820C> <BABE_FACE> <BABE_FACE> <0000_0003> <0000_0004> <0000_0005> ….. <0002_D002>
And a termination byte <55> is added (with BE_0 enabled only) between each such frame with a header.
The header is 12 bytes <0000_820C> <BABE_FACE> <BABE_FACE>, followed by 1440x512 = 737280 bytes, which is <0000_0003> ~ <0002_D0002>
Many thanks

The purpose of this sample design is to provide four video input channels to the FT602. Each channel can
be configured to QVGA, VGA, HD or Full HD independently with YUV 4:2:2 video formats.
Can I confirm it also supports uncompressed gray, please?

A video frame starts with twelve bytes of header 0x0000_820C, 0xBABE_FACE, 0xBABE_FACE and ends
with one terminating byte, 0x55. A frame may be terminated anytime by writing the terminal byte to end
frame transmission. The terminal byte signals to FT602 that the frame has ended prematurely or
otherwise. FT602 does not transmit the terminal byte to the USB host.
