Abstract: The present invention provides a debugging system and method for an embedded device, including: an embedded device, including a processing unit and a memory unit, where the memory unit includes a staging area used to store debugging data; a mobile storage device, including a debugging data control unit and a storage unit; and a computer, electrically connected to the embedded device and the mobile storage device. The debugging data control unit transmits a debugging demand message to the embedded device by using the computer. The embedded device transmits the debugging data in the staging area back to the computer. The computer transmits the debugging data to the mobile storage device and stores the debugging data in the storage unit.

Abstract: A Bluetooth pairing system includes an external device and a host device. The external device includes a Bluetooth module, a first transmission interface and a USB controller. When the external device is connected with the host device, a standard handshaking message complying with a USB communication protocol is issued from the processor to the external device. After the standard handshaking message is received by the USB controller of the external device, a device descriptor of the external device is transmitted from the USB controller to the host device. The device descriptor contains a vendor identification code, a product identification code, a product string and a product type of the external device and a target communication address of the Bluetooth module. The host device analyzes the device descriptor to acquire the target communication address of the Bluetooth module.

Abstract: A luminous keyboard with a gaming function includes a gaming program, plural keys, plural light-emitting elements and a control unit. When one of the plural keys is pressed down, a corresponding pressing signal is generated. When one of the plural light-emitting elements is turned on to emit a light beam, the corresponding key is illuminated. The control unit is connected with the plural keys, the plural light-emitting elements and the gaming program. The control unit turns on or turns off the plural light-emitting elements according to settings of the gaming program. Alternatively, the control unit turns off the light-emitting element corresponding to the illuminated key when the control unit receives the pressing signal corresponding to the illuminated key. In such way, the luminous keyboard can be used to play a game.
