LCD RAM R/W Command
The display RAM is a static 60×8×2 bits of RAM for storing LCD data. A logic "1" indicates
the "on" state of the corresponding segment and a logic "0" represents the "off" state. The
display memory address has a one-to-one correspondence with the segment output while
individual bits correspond to the column output. This mapping is used to map the RAM
data to the LCD to display the desired image.
It supports a page storage function. When the duty
≦
1/8, the user can write data to page
0 and page1 of the RAM and select the corresponding page storage to display using a
control command.
The communication data transmission format is as follows:
MSB LSB
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0
D7 D6 D5 D4 D3 D2 D1 D0
