This is a project I made because I wanted to use an old Dell full-sized keyboard on my laptop. The key feel of this keyboard is very good and I type a lot, you know. The hardware is identical to [wiki:ak2usb]. Only the firmware is different. As both devices use an usb bootloader, it is easy to switch from one to the other as needed. == Hardware == Very simple hardware : * usb port done using v-usb and using their reference schematics * PS/2 port done using my own library, bit-banging * A jumper for firmware upgrade Single side PCB with some SMD parts to make it smaller == Bootloader == I used the USBaspLoader, which takes some space (1024 bytes) on the device but is easy to work with and appropriate for this kind of devices. There is a jumper on the board you have to fit to enable upgrade mode. Else it will start in regular mode and act as a keyboard. == Software == Not done yet !
