Synopsis

SmallyMouse2 is the AT90USB1287 firmware source code and KiCAD schematic/PCB design for the SmallyMouse2 project.

Motivation

SmallyMouse2 is a project that creates a USB mouse adaptor for retro computers that use quadrature mouse input including the Acorn BBC Micro, Acorn Master series, Commodore Amiga, Atari ST, busmouse compatible computers and many more. SmallyMouse2 provides both a generic mouse output header (for attaching mouse to retro computer cables) and an IDC connector suitable for use with Acorn 8-bit user-ports. SmallyMouse2 also features a configurable quadrature rate limiter that prevents VIA overrun when in use with slower 8-bit machines.

SmallyMouse2 supports both JTAG and USB bootloader programming. The AT90USB1287 is pre-programmed by Atmel with the (FLIP) DFU bootloader; this bootloader is recognised by Atmel Studio as a programming device and can be used to flash the firmware to the board.

Installation

Note: This is an Atmel Studio 7 project that can be loaded and compiled by the IDE
