AVR ATMEGA328P Baremetal

Motivation

So I started this quest on doing Baremetal programming of AVR micro-controllers just using

• avr-gcc for compilation and object, elf file creation
• avr-objcopy for creating hex file from elf file
• avrdude and arduino programmer for flashing the chip.
• make for automating the build, hex file generation process and flashing purposes.

Working Environment

• I’m building these projects in Ubuntu 22 Linux. (Hence the documentation will contain information on how to replicate the projects here in Debian based Linux OS systems.
