HDMI CEC decode - bit ordering


ca_michelle

Question

Hi,

I've been trying the HDMI CEC decode with AD2 on waveforms (version 3.16.3), and it looks like the bit order is wrong, it should be MSB first for each nibble/byte.

I found this old forum post, which requested it's creation.


So in the example on that post, it should decode to

Start, Src h8, Dst h1, End, Ack 0,....

There's no option to switch between LSB and MSB, only invert the polarity, which doesn't fix the issue.
And no way to modify scripts for existing protocols, only create a custom one from scratch.

Is there any chance this could be corrected?, as reordering the bits manually defeats the object of having a protocol decode.

I did comment on the post, but as no-one else was following it, I thought it better to create a new post, and link to the old one.
I'm new to the site, so not sure if that is the best way to do it.

Thanks,

Michelle
