lcd-splc780d-4bitmode-board.h Board-specific LCD info for these boards:
Avnet AV110 (XT-AV110)
Xilinx ML605 (XT-ML605)
Xilinx KC705 (XT-KC705)
Interface between board-independent driver and board-specific header.
This is used by a board-independent SPLC780D LCD controller (4 bit mode)
driver to obtain board-specific information about LCD displays on the board,
such as the controller register base address and spacing (a function of how
the address lines are connected on the board) and length of the visible window
of the display (a function of the LCD panel the controller drives).
The driver doesnot refer directly to the board-specific header, which therefore is not
constrained to use macro names consistent with other boards.
!! Must not contain any board-specific macro names (only controller specific) !!
Included at compile-time via an include path specific to the board.
The listed boards contain a single MYTech MOC-16216B-B display driven by
a Sunplus SPLC870D controller.
