i have a movbile phone got the graphics LCD display and i must connect it with the processopr
where are the shematics for this. the last link you gave me was not gopod.
Poster wanted to use > mobile phones graphics LCD your link has not got this, only standard types, they cost a lot of money.
and are not mobile phones graphics LCD
i have used a graphics lcd and am the expert on this subject. here is my advice to you.
The primary means a program accesses specialized hardware for graphics, and other IO is through the memory-mapped IO. Memory mapped IO is a means of communicating with hardware by writing to/reading from specific memory addresses that are "mapped" to internal hardware functions.
with the graphics lcd, you write to address 0x4000000 with the value "0x0100", which tells the hardware "enable background 0 and graphics mode 0". A secondary means is through the BIOS, you must call the entry at 0x41001028 witn the code and value.
Using software interrupts it is possible to access pre-programmed (and hopefully optimized) routines lying in the the system ROM. These routines then access the hardware through the memory-mapped IO.

Say, expert, where did you bring these addresses from? I mean, you make a series of fantastic statements without knowing ANYTHING about the OP's hardware. Shall we all access 0x41001028 to get the answer to my question?
ashumud,,,,
youre sugestions are very good and i did not know about the memmary mapped io.
i can use it soon i think.
where can i get your code???
"where did you bring these addresses from?"
I guess these two must be in the same class...?
