zig-ssd1306-gddram-fonts

A Zig font library for SSD1306 OLED screens, designed to print text using GDDRAM.
This library provides easy-to-use font routines compatible with Zig-based firmware for embedded devices.

Features

• 8x8 pixel font for SSD1306 OLED screens
• Draws text directly to a buffer or via allocator
• Designed for Zig firmware targeting microcontrollers
• Simple integration with Zig's package manager
• Supports Zig v0.14+

Installation

Fetch the library and save it to your dependencies:

zig fetch --save=font8x8 git+https://github.com/Gnyblast/zig-ssd1306-gddram-fonts

Add to your build.zig:

const font8x8 = b.dependency("font8x8", .{});
firmware.add_app_import("font8x8", font8x8.module("font8x8"), .{})

Usage

Import Fonts

const font8x8 = @import("font8x8").Fonts;

Draw to Buffer

var buff: [88]u8 = undefined; // 8*str.len because it's 1 byte font
var printable = font8x8.draw(&buff, "Hello World");
lcd.write_gdram(printable);

Draw via Allocator (if MCU supports)

var da = std.heap.DebugAllocator(.{}){};
var alloc = da.allocator();
var printable = font8x8.drawAlloc(alloc, "Hello World");
defer alloc.free(printable);
lcd.write_gdram(printable);

Requirements

• Zig v0.14 or later
• SSD1306-compatible display
• Zig build system (build.zig)
