/* P14201 Configuration Settings:
|
|
*
|
|
* CONFIG_P14201_SPIMODE - Controls the SPI mode
|
|
* CONFIG_P14201_FREQUENCY - Define to use a different bus frequency
|
|
* CONFIG_P14201_NINTERFACES - Specifies the number of physical P14201 devices that
|
|
* will be supported.
|
|
* CONFIG_P14201_FRAMEBUFFER - If defined, accesses will be performed using an in-memory
|
|
* copy of the OLEDs GDDRAM. This cost of this buffer is 128 * 96 / 2 = 6Kb. If this
|
|
* is defined, then the driver will be fully functional. If not, then it will have the
|
|
* following limitations:
|
|
*
|
|
* - Reading graphics memory cannot be supported, and
|
|
* - All pixel writes must be aligned to byte boundaries.
|
|
*
|
|
* The latter limitation effectively reduces the 128x96 disply to 64x96.
|
|
*
|
|
* Required LCD driver settings:
|
|
* CONFIG_LCD_P14201 - Enable P14201 support
|
|
* CONFIG_LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will be accepted.
|
|
* CONFIG_LCD_MAXPOWER must be 1
|
|
*
|
|
* Required SPI driver settings:
|
|
* CONFIG_SPI_CMDDATA - Include support for cmd/data selection.

|
* Name: rit_initialize
|
|
*
|
|
* Description:
|
|
* Initialize the P14201 video hardware. The initial state of the OLED is fully
|
|
* initialized, display memory cleared, and the OLED ready to use, but with the power
|
|
* setting at 0 (full off == sleep mode).
|
|
*
|
|
* Input Parameters:
|
|
*
|
|
* spi - A reference to the SPI driver instance.
|
|
* devno - A value in the range of 0 throuh CONFIG_P14201_NINTERFACES-1. This allows
|
|
* support for multiple OLED devices.
|
|
*
|
|
* Returned Value:
|
|
*
|
|
* On success, this function returns a reference to the LCD object for the specified
|
|
* OLED. NULL is returned on any failure.
