HD61202及其兼容控制驱动器的指令系统
1 显示开/关指令
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 0 1 1 1 1 1 1/0 3e关/3F开
当DB0=1时LCD显示RAM中的内容DB0=0时关闭显示
2 显示起始行ROW 设置指令
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 1 1 显示起始行0 63
该指令设置了对应液晶屏最上一行的显示RAM的行号
有规律地改变显示起始行可以使LCD实现显示滚屏的效果
3 页PAGE 设置指令
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 1 0 1 1 1 页号0 7
显示RAM共64行分8页每页8行
4 列地址Y Address 设置指令
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 1 显示列地址0 63
设置了页地址和列地址就唯一确定了显示RAM中的一个单元,这样MPU就
可以用读写指令读出该单元中的内容或向该单元写进一个字节数据
5 读状态指令
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
1 0 BUSY 0 ON/OFF REST 0 0 0 0
该指令用来查询HD61202 及其兼容控制驱动器的状态各参量含义如下
BUSY 1-内部在工作0-正常状态
ON/OFF 1-显示关闭0-显示打开
REST 1-复位状态0-正常状态
在BUSY和REST状态时除读状态指令外其它指令均不对HD61202
及其兼容控制驱动器产生作用,在对HD61202及其兼容控制驱动器操作之前
要查询BUSY状态以确定是否可以对HD61202及其兼容控制驱动器进行操作
6 写数据指令
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 1 写数据
7 读数据指令
R/W D/I DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
1 1 读显示数据
读写数据指令每执行完一次读写操作,列地址就自动增一,必须注意的是
进行读操作之前必须有一次空读操作紧接着再读才会读出所要读的单元中的数据
