"Power can be supplied to the Multimedia Expansion Board through the DC

9-14V power supply to the DC connector, the Multimedia Expansion Board

to use 9-14V power supply."

LCD Header files
|
||||
================
|
||||
|
||||
include/nuttx/lcd/lcd.h
|
||||
|
||||
Structures and APIs needed to work with LCD drivers are provided in
|
||||
this header file. This header file also depends on some of the same
|
||||
definitions used for the frame buffer driver as privided in
|
||||
include/nuttx/fb.h.
|
||||
|
||||
struct lcd_dev_s
|
||||
|
||||
Each LCD device driver must implement an instance of struct lcd_dev_s.
|
||||
That structure defines a call table with the following methods:
|
||||
|
||||
- Get information about the LCD video controller configuration and the
|
||||
configuration of each LCD color plane.
|
||||
|
||||
int (*getvideoinfo)(FAR struct lcd_dev_s *dev,
|
||||
FAR struct fb_videoinfo_s *vinfo);
|
||||
int (*getplaneinfo)(FAR struct lcd_dev_s *dev, unsigned int planeno,
|
||||
FAR struct lcd_planeinfo_s *pinfo);
|
||||
|
||||
- The following are provided only if the video hardware supports RGB
|
||||
color mapping:
|
||||
|
||||
int (*getcmap)(FAR struct lcd_dev_s *dev,
|
||||
FAR struct fb_cmap_s *cmap);
|
||||
int (*putcmap)(FAR struct lcd_dev_s *dev,
|
||||
FAR const struct fb_cmap_s *cmap);
|
||||
|
||||
- The following are provided only if the video hardware supports a
|
||||
hardware cursor:
|
||||
|
||||
int (*getcursor)(FAR struct lcd_dev_s *dev,
|
||||
FAR struct fb_cursorattrib_s *attrib);
|
||||
int (*setcursor)(FAR struct lcd_dev_s *dev,
|
||||
FAR struct fb_setcursor_s *settings);
|
||||
|
||||
- Get the LCD panel power status (0: full off - CONFIG_LCD_MAXPOWER:
|
||||
full on). On backlit LCDs, this setting may correspond to the
|
||||
backlight setting.
|
||||
|
||||
int (*getpower)(struct lcd_dev_s *dev);
|
||||
|
||||
- Enable/disable LCD panel power (0: full off - CONFIG_LCD_MAXPOWER:
|
||||
full on). On backlit LCDs, this setting may correspond to the
|
||||
backlight setting.
|
||||
|
||||
int (*setpower)(struct lcd_dev_s *dev, int power);
|
||||
|
||||
- Get the current contrast setting (0-CONFIG_LCD_MAXCONTRAST) */
|
||||
|
||||
int (*getcontrast)(struct lcd_dev_s *dev);
|
||||
|
||||
- Set LCD panel contrast (0-CONFIG_LCD_MAXCONTRAST)
|
||||
|
||||
int (*setcontrast)(struct lcd_dev_s *dev, unsigned int contrast);
|
||||
|
||||
Binding LCD Drivers
|
||||
===================
|
||||
|
||||
LCD drivers are not normally directly accessed by user code, but are
|
||||
usually bound to another, higher level device driver. In general, the
|
||||
binding sequence is:
|
||||
|
||||
1. Get an instance of struct lcd_dev_s from the hardware-specific LCD
|
||||
device driver, and
|
||||
2. Provide that instance to the initialization method of the higher
|
||||
level device driver.
|
||||
|
||||
Examples: /drivers/lcd/
|
||||
=======================
|
||||
|
||||
Re-usable LCD drivers reside in the drivers/lcd directory:
|
||||
|
||||
nokia6100.c. Supports the Nokia 6100 display with either the Philips
|
||||
PCF883 or the Epson S1D15G10 display controller. This LCD is used
|
||||
with the Olimex LPC1766-STK (but has not been fully integrated).
|
||||
|
||||
p14201.c. Driver for RiT P14201 series display with SD1329 IC
|
||||
controller. This OLED is used with older versions of the
|
||||
TI/Luminary LM3S8962 Evaluation Kit.
|
||||
|
||||
ug-9664hswag01.c. OLED Display Module, UG-9664HSWAG01", Univision
|
||||
Technology Inc. Used with the LPC Xpresso and Embedded Artists
|
||||
base board.
|
||||
|
||||
Examples: configs/
|
||||
==================
|
||||
|
||||
There are additional LCD drivers in the configs/<board>/src directory
|
||||
that support additional LCDs. LCD drivers in the configuration directory
|
||||
if they support some differ LCD interface (such as a parallel interface)
|
||||
that makes then less re-usable:
|
||||
|
||||
configs/sam3u-ek/src/up_lcd.c.
|
||||
|
||||
configs/hymini-stm32v/src/ssd1289.c.
|
||||
|
||||
SSD1289
|
||||
|
||||
configs/sam3u-ek/src/up_lcd.c
|
||||
|
||||
The SAM3U-EK developement board features a TFT/Transmissive color
|
||||
LCD module with touch-screen, FTM280C12D, with integrated driver IC
|
||||
HX8346.
|
||||
|
||||
configs/stm3210e-eval/src/up_lcd.c
|
||||
|
||||
This driver supports the following LCDs:
|
||||
|
||||
1. Ampire AM-240320LTNQW00H
|
||||
2. Orise Tech SPFD5408B
|
||||
3. RenesasSP R61580
|
||||
|
||||
configs/skp16c26/src/up_lcd.c. Untest alphanumeric LCD driver.
