# pico-pcd8544
2+
3+
A simple library for the PCD8544 LCD controller (Nokia 5110) for the Raspberry Pi Pico.
4+
5+
This project heavily inspired by [Adafruit's PCD8544 library](https://github.com/adafruit/Adafruit-PCD8544-Nokia-5110-LCD-library) for Arduino.
6+
7+
## Running Examples
8+
9+
### Wiring
10+
11+
| Pico Pin | PCD8544 Pin |
12+
|----------|-------------|
13+
| GP12 | RST |
14+
| GP13 | CE |
15+
| GP11 | D/C |
16+
| GP15 | DIN |
17+
| GP14 | CLK |
18+
| 3V3 | VCC |
19+
| 3v3 | BL |
20+
| GND | GND |
21+
22+
### Building and Flashing
23+
24+
```bash
25+

cd pico-pcd8544/examples/circle
27+
cmake -B build -S .
28+
cmake --build build
