| 摘 要： | 文章提出了一种基于ST7920控制器系列的MD12864C-1液晶的波形显示算法。根据波形的特点,由于液晶的行数有限,利用单片机对波形幅度值按比例的换算,再对相应点赋值,最后通过串行数据传输到液晶的数据RAM,最后实现了正弦波形的显示。

| Abstract: | This paper presents a controller based on the ST7920 series of MD12864C-1 liquid crystal display of the waveform algorithm.According to the waveform characteristics,due to the limited number of liquid crystal line,using the monolithic integrated circuit to the waveform amplitude proportional to the conversion,then the corresponding point assignment,finally through the serial data to the data of RAM liquid crystal,finally realize the sinusoidal waveform display. |
