lightweight C Vector Font Rendering Engine For Embedded MCU

Overview

I decided to write the Vector Font because I needed a font with different sizes and optimized for a microcontroller, and there wasn't any clear library that had this feature. In starting this, I have had to write a library for myself, and this repo was born. Currently, it only supports upper-case ASCII, numbers, and some of the necessary symbols, as that is all that is required to write something on a screen.

Features

• Simulation in Windows using SDL3 & CMD
• Font 10x10 px
• All development is in the 'C' programming language.
• The numeric data type is integer by default
• Flexibility
  • variable size
  • variable depth
• support for runtime scaling of fonts
• quadratic bezier curve
