| Abstract: | A vehicular information system based on the ADI DSP chip and SHARP TFT-LCD LQ104V1DG52 was proposed in this paper.The hardware interface circuit between ADSP-BF536 and LQ104V1DG52 was designed,the LCD driving software was programmed,and the LCD control signal time sequence was analyzed.After all,the system was tested for information display.The experiment results show that the vehicular information system can display the information clearly and stably and meet the design requirement entirely. |
