Experimental c-runtime implementation for Atmega328p

Custom Runtime (CRT) Project for ATmega328P

This project outlines how to create a custom runtime for the ATmega328P, incorporating a custom mathematical utility library for operations not natively supported by the hardware.

Requirements

• Hardware: ATmega328P-based board
• Software:
  • avr-gcc: AVR toolchain for compiling your code.
  • avr-objcopy: Tool for converting the compiled output into various formats.
  • avrdude: Software for uploading the firmware to the microcontroller.
  • GNU Make: Build automation tool to run the Makefile.
  • screen: Utility for serial communication with your board.
• Operating System: macOS and Linux.

Setup

1. Install Required Software:
   • On Debian/Ubuntu: sudo apt-get install gcc-avr avr-libc avrdude make screen
   • On macOS (using Homebrew): brew install avr-gcc avrdude avrdude --with-usb
