According to the data sheet of the AM2301, it uses the exact same protocol
(with 40 bits). There are 24 additional bits at the end, all zeros. Never
seen something like this before. As they are cheap, I ordered an AM2301. I
can then try to reproduce your observation.
Ok, cool.
I can now confirm that the AM2301 adds three empty bytes at the end of
each transmission. The current implementation ignores this data. We
might as well add some special handling for this case to the decoder,
but I guess it is not worth the trouble.
I could also get my hand on some devices from the AM232x product line.
They support single wire communication as well as I2C, although I did
not check the latter. The two patches attached to this mail add example
dumps for AM2320, AM2321 and AM2322 as well as matching test cases to
sigrok-dumps and sigrok-test, respectively.
I will add pictures of these sensors to the wiki page within the next days.
The current name does not reflect the growing number of supported
devices. Something generic, like "am23xx" or "aosong_onewire" might be
more appropriate. Any ideas on this?
Best regards,
Johannes
