This article introduces a wireless control system for the camera. The upper computer of the system is S3C2440 ARM. With the Bluetooth Serial Port data is transmitted from upper computer to the Single-Chip computer. The CSR BC417/143BQN is the core of the Bluetooth wireless Serial port module. Square wave is generated to control the camera after the Single-Chip microcomputer received the data, the scheme has been achieved with hardware, and it has been proved good to control the camera through test. The method described in this article has some reference value to other wireless control system.
