#149 Lcd5110/JuliansU8glibDemo
Quick test drive of Julian Ilett’s 5110 LCD demo with the u8glib library
Notes
Nothing new here, I’m just testing Julian’s Ardutorials: Arduino, Nokia 5110 LCD & u8glib.
SPI Configuration
The u8glib takes advantage of hardware SPI, which means pin connections are dictated for at least MOSI and SCK.
Here’s the mapping from the terminology used by my particular 5110 module and pins on an Arduino Uno.
| Pin | Usage | Arduino Uno Pin |
|---|---|---|
| RST | reset | 8 |
| CE/SCE | chip enable | 10 SPI SS |
| DC | address line 0 | 9 |
| DIN | data in | 11 SPI MOSI |
| CLK | clock | 13 SPI SCK |
| VCC | power | |
| BL | Backlight on when GND | |
| GND | Ground |
