lcd1602液晶屏使用8位并行传输数据，因为这样需要引脚比较多，所以有这个想法是否可以向12864那样串行传输数据。但是1602不向12864有串行模式，它只有一个并行模式。这时组内有人提出可以使用74HC595这个芯片，它的特性正好是8位串行输入转平行输出。
接下来开始讨论控制的时序图，1602的时序图十分简单，我们用用画图得出了串行下的时序。
-LCD1602 LCD screen using 8 bit parallel transmission of data, because it requires a lot of pins, so there is the idea of whether the serial data can be transmitted to the 12864. But 1602 does not have a serial mode to the 12864, it has only one parallel mode. At this time it was proposed that the group can use the 74HC595 chip, which is precisely the 8 bit serial input parallel output.
Next, we start to discuss the timing diagram of the control, and the sequence diagram of 1602 is very simple.
Due to the limitation of conditions, the simulation software is used to simulate the effect.
