APC SU1400RM2U: display pinout and LED driver reconstruction

An Arduino sketch reconstructs control of the APC SU1400RM2U display panel from its cable pinout and LED mapping. It identifies the A6276ELW LED driver, assigns latch, clock and serial-data lines, and demonstrates individual and sequential LED updates.
