# Sony CDX-A250: reconstructing the LCD panel interface

> Sony CDX-A250 LCD Panel reconstructs the serial control needed to drive the radio's detachable display independently through its LC75826W driver. Wiring notes, CCB transfer documentation, and an Arduino sketch cover display-data groups, control bits, test patterns, and experimental segment mapping.
