摘要
蒙古文是我国少数民族——蒙古族使用的文字,研究蒙古文的信息处理具有重要的意义。本设计在借鉴西文、中文输入显示技术的基础上,根据蒙古文的特点,开发了基于单片机的蒙古文输入显示系统。该系统以AT89C51单片机为核心,包括128×64液晶显示器、输入设备、单片机外围电路和蒙古文字库。首先建立蒙古文字库,蒙古文字库采用点阵式,有16×16和16×32两种格式。单片机一方面从蒙古文字库取字符传送到LCD显示,另一方面通过74HC373和74HC00器件控制LCD显示。在Proteus仿真环境下对系统进行了仿真,具有良好的显示效果。
Mongolian is character used by Mongolia people in minority areas of China. Study of Mongolian information processing is important. In reference to the western and Chinese character input display technology, the system of Mongolian input and display is developed according to Mongolian＇s features. The core of the system is AT89C51 MCU, which includes 128 × 64 liquid crystal display, input device, peripheral circuit of MCU and Mongolian character database. First Mongolian character database is established, which use a dot matrix of 16 ×16 and 16 ×32 two formats. MCU takes a character from the Mongolian character database and transmits the character to LCD display, on the other hand, controls LCD through the 74HC373 and 74HC00 devices. The system is simulated in the context of Proteus, which has a good display effect.
