Are you sure that LCD is not equal to hitachi HD series?

Actually HT1621 is a driver for this LCD.
And i am not able to get what adderss shud i assign to data.
What is the link between these 6bit addresses and (32 x4)bit ram.
Suppose i have to display 8 what should be the address of the bits to
be written.(relation between the segments of lcd and 6bit address) ???
tia

seshu,,
actually you are talking about the lcd with 32 segments and 4 com bits ...although the lcd is xiamen ocular GDM060 but its been controlled by the hitachi 1621 controller and if you want to control this seriel lcd you had to implement the control in software and that's basically by using the bit banging technique.... and for displaying the digit you need to get the memory map of this particulatr lcd ...

hope you will get the clue...
