摘要
本文介绍了流量计中微处理器以软件模拟方法产生SPI信号与液晶模块通信的过程,以及用显示缓冲实现多参数显示的处理方法。采用该思路设计的流量计经长期使用表明,系统在设计简单的条件下运行可靠。
In this paper, the communication process between microprocessor and LCD module is introduced. The microprocessor uses software simulation method to generate SPI signal. Meanwhile, display buffer is used to achieve multi-parameter display. The application indicates that the flow meter with the proposed method is simple and stable in performance.
