Hi
With the new version, the XA0/XA1 - I/O Expander I2C address has been removed.
How do you control multiple clusterhats now without disconnecting the HAT EEPROM?

With the minimal firmware it needs a recompile. I'll compile the firmware for the previously supported I2C addresses and add tidied instructions to compile/upload the firmware to the GitHub repo ( https://github.com/8086net/clusterhat26-firmware ) as soon as I can.
Chris.
