# ***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
