新用了一个液晶显示器,和以前的接线不一样,这个显示是反向的,在不改变显示字体的情况下,有可以配置寄存器让显示反转吗?
附上ST7567的初使化显示代码和液晶datasheet~

write_byte(LCD_CMD,0xA3); // set lcd bias = 1/7
write_byte(LCD_CMD,0x24); // set internal rb/ra=5.0

v_LCD_Write_Windows(SEG_ORG_OFFSET,131,0,8,0x00);
write_byte(LCD_CMD,0x2f); // all built-in power circuits on
write_byte(LCD_CMD,0x81); // set contrast
write_byte(LCD_CMD,0x1c); //vop
write_byte(LCD_CMD,0xaf); // dispaly on
}
这个只是改变扫描的顺序,也就是先扫后扫的问题,对屏的反转并没有用的~
知道是哪个寄存器吗?我试了不管用呢~
w_cmd(0xC8); //SHL selection(COM0->COM64) //com select,NORMAL 0-->63(c8,c0)//上下镜像
WrateC(0xA0);//ADC seg
镜像选择
0xa0
正常,
0xA1
左右镜像
WrateC(0xc0);//com output scan direction
,
com
镜像选择
0xc0
正常,
0xC8
上下镜像
试了不管用的。
