NFP1315-61A

Small library for the NFP1315-61A display. It use an SSD1306 driver, with an I2C communication bus. It aims at being very simple and minimalistic, and is compatible with esp-hal, embedded-hal, ...

Display

This display is 128x64 pixels. To draw text, you need to specify the position by the column and page. There is 8 page, each 8 pixel tall, wich correspond to the size of one character.

Usage

Create the SSD1306 struct:

use nfp1315::SSD1306; // import the library

// the library is build around embedded-hal, so it is compatible with many µC
// you can create an I2C instance with your board and SSD1306 will take ownership of it
// SSD1306 is not multi-bus
let mut display = SSD1306::new(i2c, 0x3C); // create the SSD1306 struct with the NFP1315-61A address: 0x3C
display.init_display();

Functions:

display.clear(); // clear the display (Black)
display.fill(); // fill the display (White)
display.draw_text(text: &str, col: u8, page: u8); // draw text to the display at the position (col, page)

All function of SSD1306 return a Result<(), Error>. You can catch it with a match statement.

match display.draw_text("Hello World", 50, 0) {
    Ok(_) => {}
    Err(e) => //...
}
