摘　　要：介绍单片机拼音输入法,由单片机采用折半查找算法定位其在“拼音-首汉字位移表”中的位置,检出对应的首汉字位移,映射按拼音排序的“汉字内码表”,根据其内码计算出其字模在“字模表”中位置,并将字模检出送至LCD显示。Micro Control Unit (MCU) implies binary search arithmetic to locate the position of inputted Chinese character's PINYIN in ″PINYIN-First Chinese Character Offset Table″.When getting the relevant offset,the MCU then maps it to ″Chinese Character Internal Code Table″ and depends the internal code for calculating the address of the first Chinese character's dot matrix in ″Chinese Words Dot Module Table″,afterwards bring the special dot matrix to LCD for showing.
