【正文】 converter used sampling signal , a arithmetic module and the LED demonstration to achieve the function of handwritten drawing, the emphasis of it is improving the sensitivity and Low power consumption .The signal modulator ensures the sampling requirements and measurement accuracy with the help of 24 bits A/D converter. The reasonable design ensures low power consumption. This system in C language software design,increases the readability of the program the software design using modular structure, make the program design logical relationship more concise and clear. Keywords: handwritten drawing； LM3S3748； accuracy； low power consumption 2020 年全國大學(xué)生電子設(shè)計大賽設(shè)計 報告 1 目 錄 摘 要 ..............................................................................................................................
