Setup

This file explains how to setup the project to be run on both linux and wsl.

Installation for Linux

Ensure the system is up to date:

sudo apt-get update
sudo apt-get upgrade -y

Then install avr and avr-dude:

sudo apt-get install gcc-avr binutils-avr avr-libc
sudo apt-get install avrdude
sudo apt-get install ruby cmake

USB passthrough for WSL

If using wsl2 then usb can be passed through using the following commands. First find all usb devices attached to the host by running:

usbipd list

in an admin ps prompt. Then bind and attach the device using:

usbipd bind --busid <busid>
usbipd attach --wsl --busid <busid>

To find all the attached devices on the linux machine run:

lsusb

A device can be detached using:

usbipd detach --busid <busid>

Compilation for the atmega328p

Create the object file using avr-gcc:

avr-gcc -Os -DF_CPU=16000000UL -mmcu=atmega328p -c -o project.o project.c

Then create the executable:

avr-gcc -mmcu=atmega328p project.o -o project

Then convert to binary executable:

avr-objcopy -O ihex -R .eeprom project project.hex

Then flash to the micro controller:

avrdude -F -V -c arduino -p ATMEGA328P -P /dev/ttyUSB0 -b 115200 -U flash:w:project.hex

Sometimes the device can be at other bus locations including ttyACM* the correct location can be found using:

ls -l /dev/ttyUSB* /dev/ttyACM*
