#GNU #Linux #Tutorial #Driver #DriverDevelopment Let's take a closer look at USB. In this series of tutorials we will learn how to implement an USB device on a microcontroller and interact with it over our GNU/Linux OS from user- and kernelspace. Today we will implement the first functionality into our Atmega32U4 USB device. With control transfers we will control a two digit seven segment display. Therefore we will write some firmware in C and implement a test program by using Python and pyusb. 00:00 Intro 00:37 Theory 04:25 Implementing Firmware 12:06 Testing with Python You can find the source code here: https://github.com/johannes4Linux/usb_tutorial You want to support my work?
