LED-tape based segment display

This is a work-in-progress repository containing hard- and software source files for an 8-segment LED display based on cheap single-color LED tape. The display consists of one digit driver per display digit that receive power and transceive data through a two-wire powerline bus. This bus can support 10-50 digits depending on the size of the display (and thus current consumption). The bus is driven by a driver board that is in turn controlled through RS-485.

The hardware is mostly finalized and can be found in center (digit controller) and driver (bus driver). The firmware is still WIP and can be found in center_fw (digit controller), driver_fw (bus driver) and common (common 8b10b implementation).
