摘　　要：用PC机与单片机串行通信传送需所要显示汉字的机内码,单片机根据机内码从汉字横向点阵字库中提取点阵数据,并对其进行旋转90°变换,使之成为纵向点阵数据后送LED显示屏扫描显示.The displayed Chinese characters transport between PC and single-chip microcomputer serial communication needs code conversion.According to the ISN,SCM extracts the bitmap data from Chinese character transverse bitmap data,and then rotate 90 ° transform.After the code become longitudinal bitmap data it is sent to the LED display screen to be scanned.

关 键 词：单片机 串行通信 汉字点阵数据 旋转90°变换
