Prerequisites

install the toolchain:

• avr-gcc
• avr-binutils
• make
• avrdude

Quick Start

1. Get the files

git clone https://github.com/mfbsouza/avr-bare-metal.git

2. Write your code

write your code in main.c and create how many source files you want and compile it with:

make

3. (Optional) Analyse it

take a look at the build/memory.map and build/firmware.lst files to check if everything is in other as expected.

4. Flash it

Plug yout AVR Microcontroller with a bootloader and just:

./scripts/flash.sh -P <port> -m <mcu> -c <programmer> -b <path_to_hex>

Ex:.

./scripts/flash.sh -P /dev/ttyACM0 -m atmega328p -c arduino -b build/release/firmware.hex
