12864串口程序

4.串口程序5.6.PSB接低时,串口模式被选择。

在该模式下，只用两根线(SID与SCLK)来完成数据传输。

当同时使用多颗ST7920时，CS线被配合使用，CS 是高有效。

ST7920 的他不时钟SCLK 有独立的操作时序，当多个连续的指令需要被送入时，指令执行时间需要被考虑。

必须等待上一个指令执行完毕才送入下一个指令，因为ST7920内部没有传送/接收缓冲区一个完整的串行传输周期由一下部分组首先送入启动字节，送入5 个连续的“数被重置，并且串行传输被同步。

紧接的两是写）和传输性质（RS，确定是命令寄存器一个“0” 。

送完启动字节之后，可以送入指令或是者代码是以字节为单位的，每个字节的内容字节来处理：高四位放在第一个字节的高四无关位都补“0” 。
