drivers/lcd and configs/olimex-lpc1766stk: Remove support for the Nokia6100 LCD. That LCD uses a 9-bit SPI interface (the 9th bit being the command/data bit that is normally a discrete). That communication was never successfully integrated. I now believe that it would would require some special support from the low-level, MCU SPI driver to manage that 9th bit. The deleted code is still available in the Obsoleted repository in the nuttx/drivers/lcd, nuttx/configs/olimex-lpc1766stk, and Patches directories.

STATUS: The LCD driver was never properly integrated. It is awkward

to used because it relies on a 9-bit SPI inteface (the 9th bit being

the command/data bit which is normally a discrete input). All support

* CONFIG_NOKIA6100_SPIMODE - Controls the SPI mode
|

* CONFIG_NOKIA6100_FREQUENCY - Define to use a different bus frequency
|
||||
* CONFIG_NOKIA6100_NINTERFACES - Specifies the number of physical Nokia
|
||||
* 6100 devices that will be supported.
|
||||
* CONFIG_NOKIA6100_BPP - Device supports 8, 12, and 16 bits per pixel.
|
||||
* CONFIG_NOKIA6100_S1D15G10 - Selects the Epson S1D15G10 display controller
|
||||
* CONFIG_NOKIA6100_PCF8833 - Selects the Phillips PCF8833 display controller
|
||||
* CONFIG_NOKIA6100_BLINIT - Initial backlight setting
|
||||
*
|
||||
* The following may need to be tuned for your hardware:
|
||||
* CONFIG_NOKIA6100_INVERT - Display inversion, 0 or 1, Default: 1
|
||||
* CONFIG_NOKIA6100_MY - Display row direction, 0 or 1, Default: 0

* CONFIG_NOKIA6100_MX - Display column direction, 0 or 1, Default: 1

* CONFIG_LCD_NOKIA6100 - Enable Nokia 6100 support
|

* CONFIG_LCD_MAXCONTRAST - must be 63 with the Epson controller and 127 with

* CONFIG_LCD_MAXPOWER - Maximum value of backlight setting. The backlight
|
||||
* control is managed outside of the 6100 driver so this value has no
|

* meaning to the driver. Board-specific logic may place restrictions on
|
||||
