# classic hardware

## Overview
The classic device was created several years ago to fill a single need, preventing my work computer from auto locking due to inactivity. *Subverting security policy comes with a responsibility to ensure that you lock your computer (CTRL+ALT+DEL) everytime you walk away!*  

Alternatively the device can also be used as a low-pin USB development platform, by soldering a pin header to the exposed pads on the bottom you can access 3 GPIOS, VCC (3v3+), GND and the RESET pin of the ATTINY85. Making it a very low-pin count development board with USB capabilities.

## Firmware
The firmware makes use of the outstanding V-USB software-only implementation of low-speed USB devices. If you plan on making changes or releasing your own devices please change the vendor/device names as well as the vendor/product ids within the [usbconfig.h](fw/v1/usbconfig.h) file.
    
`V-USB` is released under the [GPLv2](https://github.com/obdev/v-usb/blob/master/usbdrv/License.txt) license.

## Bootloader
Micronucleus is the bootloader that is currently in use by the beeon-classic devices. You will need a copy of the commandline tool for your operating system inorder to upload new firmware onto the device. v2.04 is the version that we are currently using.
