ferret-arduino-adafruit-pcd8544

===============

Wrapper for the Adafruit Arduino driver for PC8544, most commonly found in Nokia 5110.

#### Dependencies

 - Adafruit-PCD8544-Nokia-5110-LCD-library - `https://github.com/adafruit/Adafruit-PCD8544-Nokia-5110-LCD-library`

 - Adafruit-GFX-Library - `https://github.com/adafruit/Adafruit-GFX-Library`

Both available via Arduino library manager. 

#### Usage

    (require '[ferret-arduino-adafruit-pcd8544.core :as lcd])

    ;; Software SPI (slower updates, more flexible pin options):

    ;; pin 7 - Serial clock out (SCLK)

    ;; pin 6 - Serial data out (DIN)

    ;; pin 5 - Data/Command select (D/C)

    ;; pin 4 - LCD chip select (CS)

    ;; pin 3 - LCD reset (RST)

    (def scr (lcd/device 7 6 5 4 3))

    (lcd/begin    scr)

    (lcd/contrast scr 50)

    (lcd/clear    scr)

    (lcd/cursor   scr 0 0)

    (lcd/println  scr "Hello World")

    (lcd/display  scr)

    (forever (sleep 100))
