What if we dedicate yet another ATLAS tine - X16C0/pin A18 - to a 1-wire
bus and add a Dallas 1-wire serial number chip with EEPROM (DS2430
series, for example)? You can have a gazillion of these - more than
we'll ever have slots - and each one has a unique electronic serial
number besides. The protocol to enumerate the devices is readily
available and easy to implement.
And you can hang other goodies on the 1-wire bus, like temp sensors, or
a real time clock for Gibraltor to keep accurate, or A/D converters and
I/O ports and...
Zero impact on the I2C bus or its limited addressing space.
And - bonus time - the protocol is like morse code: dots and dashes and
spaces!
Who could ask for anything more?
