| Abstract: | The system,which could automatically adjust the exposure time of linear CCD at high speed,is realized with a new method.The method is carried out under controlling of AT89C52 (a microcontroller of ATMEL Co.Ltd).In this design,driving schedules of ILX533K (a CCD produced by SONY Co. Ltd) is analyzed in details;complex programmable logic device (CPLD) is chosen as the hardware design platform;driving schedule generator is described with VHDL.The function simulation of the system is successfully fulfilled with MAX+PLUS Ⅱ software.Then RTL simulation is fulfilled and the design is fitted into EP1K50 (a CPLD produced by ALTERA).The data of these experiments show that the system is suitable for the demand of fast automatic adjustment the exposure time of linear CCD. |
