Hello,
I'm using the below patgen script with the 964.
According to the datasheets, the default colors for the 8-bar script should be:
['AA' '33' 'F0' '7F' '55' 'CC' '0F' '80']
However, the stream that I’m getting in is:
['AA2A' 'CC0C' '3F3C' 'DD1F' '5515' '3333' 'C003' '2220']
Reordering it as little-endian, followed by the nVidia bitmasking the first/last 2 bits, and bitshift >> 2:
['AAA' '333' 'F0F' '7F7' '555' 'CCC' 'F0' '808']
As you can see, it appears that one of the words appear to repeat for each pixel.
- FO --> FOF
- 0F --> 0F0
Is this expected of 8-bit registers filling a RAW12 frame, or am I facing an upstream error?
Resolution, filesizes otherwise look ok to me.
Thanks,
M
