VCRs control system based on LANC bus protocol

With the development of economy and the improvement of science and technology, the digital camera is applied more and more widely. Most cameras also come with LANC remote control interfaces. This paper describes a LANC-based camera control system. In this system, the STC12c2052AD microcontroller communicates with the SONY digital camera by the I/O pin. Through the PC serial communication with the microcontroller, the PC control the SONY digital camera.
