Running 4.38 on this based on the Cerbuino and was wondering if there was such a thing as a serial number encoded into each IC? The 407 has a mac address by the 405 does not.
I need a way to HASH a serial number to a licence code so that I can allow the client to make his own boards but he has to licence each one and send me the serial number and I send back a licence key for each board.
I could use a serial number based EEPROM for the next batch but it would be good if I didn’t have to make new boards.
FAIL. That just reads the device ID and I get the same for both boards.
Oops. I missed the fact that one byte was different. Sorry boss.
I was going to take the piss and ask if you wanted me to test more then 3…
Is there anything you do not know about STM chips?
Actually, I wonder if I could use that for my project. Locked by license code eh?
That’s what I am going with this design. It spits out the system ID if it detects it is not licenced. After the client sends me the ID I send back a version that works with that ID. I charge per board then
Device Activation. I like it.
