Abstract
The design process of CCD signal acquisition circuit is introduced, in which the shift pulse that the CCD internal vertical shifting register requires is produced by MCU, and the CCD level shift pulse and reset pulse are produced by TMS320LF2407A chip. The circuit of analog to digital conversion and data storage is designed after the CCD output signal, and the data transmission between DSP and FIFO is controlled by the DSP and MCU. So that the processing of CCD signal is realized and the objective is measured.关键词
