What it is
===

Library for graphical LCDs for Python on Raspberry Pi. Creates a united interface for supported devices

Supported:

- ili325 via GPIO
- ssd1306 via SPI
- nju6450 via GPIO

On NJU and SSD uses buffer to keep current content as help for page operations.

Wiring is below


Initialization
===
## SSD1306
### SPI

    from driver.ssd1306.spi import SPI
    from driver.ssd1306.ssd1306 import SSD1306
    drv = SPI()
    o = SSD1306(128, 64, drv)
    o.init()

If you want to set your own pins:

    drv = SPI()
    drv.pins = {
        'RST': 13,
        'DC': 6,
    }
    o = SSD1306(128, 64, drv)
    o.init()

## NJU6450
### GPIO

    from gfxlcd.driver.nju6450.gpio import GPIO
    from gfxlcd.driver.nju6450.nju6450 import NJU6450
    drv = GPIO()
    o = NJU6450(122, 32, drv)
    o.init()

Custom wiring:

    from gfxlcd.driver.nju6450.gpio import GPIO
    from gfxlcd.driver.nju6450.nju6450 import NJU6450
    drv = GPIO()
    drv.pins = {
        'A0': 17,
        'E1': 22,
        'E2': 21,
        'D0': 23,
        'D1': 24,
        'D2': 25,
        'D3': 12,
        'D4': 16,
        'D5': 20,
        'D6': 26,
        'D7': 19,
        'RST': 5,
    }
    o = NJU6450(122, 32, drv)
    o.init()

## ILI9325
### GPIO

    from gfxlcd.driver.ili9325.gpio import GPIO
    from gfxlcd.driver.ili9325.ili9325 import ILI9325
    drv = GPIO()
    o = ILI9325(240, 320, drv)
    o.init()

Custom pins:

    from gfxlcd.driver.ili9325.gpio import GPIO
    from gfxlcd.driver.ili9325.ili9325 import ILI9325
    drv = GPIO()
    drv.pins = {
        'RS': 27,
        'W': 17,
        'DB8': 22,
        'DB9': 23,
        'DB10': 24,
        'DB11': 5,
        'DB12': 12,
        'DB13': 16,
        'DB14': 20,
        'DB15': 21,
        'RST': 25,
    }
    o = ILI9325(240, 320, drv)
    o.init()
