V-USB on an ATmega828! - V-USB and HID Explained
Sometimes, we only have access to microcontrollers without all of the peripherals that we need. Several cases like in the AVR line of microcontrollers involving USB support. Luckily there is a library called V-USB that allows us to bit-bang USB support into our projects.
