const unsigned char interfaceVersion[INTERFACE_VERSION_LENGTH] = { INTERFACE_VERSION }

Serial interface unique identifier. TODO change spec to not have numerics and to parse from string, maybe pull from somewhere?

This should only change when the serial interface changes (even a little)This field consists of 3 chars for a 3 part version number and a free form string. For any unique string the version number is also unique. In this way tools can easily support a range of versions for a specific unique string ID TODO change spec to not have numerics and to parse from string, maybe pull from somewhere?

const unsigned char firmwareVersion[FIRMWARE_VERSION_LENGTH] = { FIRMWARE_VERSION "-" BUILD_CONFIG }

Displayable firmware version identifier.

This changes automatically every time the code is changed at all (even a little) thanks to Git.
