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.
