Hi,
I have an update for the ATSHA204A decoder that adds support for the
ATECC508A device, along a couple of commits that contain bugfixes:
* https://github.com/michpappas/libsigrokdecode/tree/atecc508a
* https://github.com/michpappas/sigrok-dumps/tree/atecc508a
* https://github.com/michpappas/sigrok-test/tree/atecc508a
According to the reference documents, both ATSHA204A and ATECC508A are
backwards compatible with older models, so in addition to the above, the
decoder should now support the following devices (not tested):
* ATSHA204
* ATECC108, ATECC108A
I didn't update the decoder's description and the rest of the
information in pd.py to reflect the fact that the decoder now supports
more than one device, and I am not sure whether the decoder should be
renamed altogether or not. In their website
(https://www.microchip.com/design-centers/security-ics/cryptoauthentication)
Mirochip refers to these as Crypto Authentication devices, and provides
a library called CryptoAuthLib, so, if renamed, I guess it would be
reasonable to use something similar. In any case, please feel free to
update / rename (or not) as you see fit :-)
Best Regards,
Michalis
