Detailed Description

API to handle Nokia 5110 display through SPI interface (actually not really SPI as only MOSI, not MISO, pin is used for data transfer).

Note that PCD8544 chip used in Nokia 5110 is powered at 3.3V and does not bear 5V voltage from pins of most Arduino. Hence, all signals from Arduino output pins must be converted from 5V to 3.3V, for this you will need a level converter:

• this may be CD74HC4050 chip (up to 6 pins with level conversion)
• or you may use one of those common MOSFET-based converters breakouts
• or you may build your own

Example wiring for Arduino UNO (with CD74HC4050):

• pin 11 (PB3,MOSI) –I>– DN
• pin 13 (PB5, SCK) –I>– SCLK
• pin 10 (PB2, SS) –I>– SCE
• pin 9 (PB1) –I>– D/C
• pin 8 (PB0) –I>– RST
• 3.3V –[=330=]– LED
• 3.3V ---— 3.3V
• GND ---— GND
