bb7a579681 fleshed out rest of fileops interface; read now takes into consideration current file position (so the display can be read in multiple operations, and indiate EOF correctly), seek (really just to facilitate rewind), and unlink (to facilitate dropping from system at runtime). 2016-05-29 14:53:37 -05:00

4643fcdfd8 correct logic hazard in latch and load nybble; was transitioning control lines at the same time as enable, causing spurious behaviour on less-tolerant displays 
improve timing parameters in init sequences for better display compatibility

correct (row,col) -> address calculation; affects 4-line displays

dc1c27cee7 * This driver supports the 'I2C lcd backpack' design that is based on the PCF8574 io expander. There's a myriad of different vendors of such, but they are principally the same, save wiring and minor features like jumpers for I2C addresses. This driver supports known and unknown variants. 
*  The interface board supports HD44780-based LCD modules up to 4x32, and this driver accommodates all those formats.

beff697bc7 drivers: implements lcd interface for ili9341 
This implements the lcd interface to displaying data on the lcd display powered
by the ili9341 lcd driver.

This driver implements all methods defined in the lcd_dev_s structure except
getcontrast and setcontrast. They are not supported by the hardware.

Furthermore the driver allows to use multiple displays powered by the ili9342 IC
with only one driver instance. So it is theoretically possible to support more
than one connected ili9341 lcd display. The displays can be configured
independently. Currently two lcd devices supported. This should be enough for
now. Read the corresponding code section of how to add more devices if
neccessary.

The following settings are configurable:

1. Pixel format
   Define the pixel format of the connected display. Currently only
   RGB-565 supported.

2. Orientation
   Define the orientation of the display. This can be portrait or
   landscape and reversed values.

1. Write only
   The driver allows to disable any getrun method if not neccessary to
   reduce code size. This is done by enable CONFIG_LCD_NOGETRUN in the nuttx
   configuration.
