 ====== Crazy USB mouse ======
-ARM-CAN demo project.
+//Requirements: [HW] [[en:hardware:avr-can:controller]]//
+[{{  :images:projects:crazy_mouse:crazy_mouse_windows_cursor.png|Mouse cursor moving round}}]
+ARM-CAN USB mouse demo project. Software is based on TI StellarisWare USB library. When attaching the ARM-CAN controller board to the PC, it acts as a standard USB HID mouse. Fixed-point sine calculation functions are used to move cursor around. Push-button on the controller board acts as a left button.
