| Abstract: | A design and realization of a focusing control system of a multispectral digital camera based on CPLD was introduced.The CPLD was programmed by VHDL.The designs on serial receiver and control module were introduced emphatically.It is demonstrated by the emulation that the system can complete the function of focusing control.The design also improves the dependent and stability of the system. |
