What is it?

DIY Simple Arduino In-System-Programmer (aka perf-board USBasp clone)

Installation

Windows

Driver installation

Linux

Linux doesn't need driver installation

However, it would be more convenient to allow current user access USB instead of execute commands under root or sudo

If you ever run these steps before, they don't need to be executed again

$USER is your current login name on your machine

sudo adduser $USER dialout
sudo adduser $USER tty
sudo adduser $USER plugdev

Then log out of current desktop session and log in again, it's done.

How to use

Any software / IDE support USBasp programmer

avrdude

avrdude -u -c usbasp -P usb ...

AVRDUDESS

Arduino IDE

Tools > Programmer > USBasp
