Hi TI Expert,

For 2A algo developement, I need to parse h3a bin file. I notice sometime 16-byte 0 is padded to bin file and it's related to h3a config in dcc file.

Could you help introduce the concept of 0 padding?

I attached h3a dcc file and corresponding output bin file. 2 kinds of sensors were for comparison, AR0147 was with 0 padding but AR0233 was not.

Best regards,

I suppose you are talking the 0-padding at the end of each row of windows.

You may refer to the code below for the padding.

Please also note that there are some limitation of the number of H3A windows in each H3A working modes.

Hi Gang,

I use this code to parse bin files I attached. It seems ok even though the padding concept and reason are not clear.

Next I'm going to modify h3a config and capture bin file to verify this code again. I will feedback if any issues.

Best regards,

Zhishen
