Framebuffer Display Lab

Experimentation project with OLED SSD1306/SSD1307 displays on embedded Linux.

About

Started as a side project from Ronda Linux after installing and activating a 128x64 OLED display with framebuffer. The goal is to implement and compare three different approaches for displaying system information (temperature, CPU usage, etc.).

Implementations

• 1. Static Bitmap Fonts [🔄 In Progress]

• Fonts as C arrays

• Direct framebuffer rendering

• 2. FreeType2

• TTF/OTF font loading

• Font flexibility

• Rendering via FreeType2

• 3. LVGL

• Complete framework

• Ready-to-use widgets

• More elaborate interface

Hardware

• OLED SSD1306/SSD1307 128x64 display
• Embedded Linux with an active framebuffer
• Access via /dev/fb0

Status

Project in development, all implementations will be done in C.
