FirmwareImplementation

The firmware for this reference design is written in the C

language. The following files are required to compile the

mouse firmware.

The user should insert the receiver dongle into an available

USB port at the computer. Install two AA alkaline batteries

into the battery compartment. Pay special attention to the

polarities of the two batteries. The reference design mouse is

designed to work with two AA batteries in parallel or just one

AA battery. Press the connect button on the receiver dongle

and while the LEDs are flashing press the connect button at

the underside of the mouse. When the mouse is properly

connected to the dongle, every time it receives a transmis-

sion from the mouse the LED lights up.
