unfortunately i can't succeed...I want to explain with an example:
** The address I want to write: 0x01DE0000
** the value I want to save on this address: 0x0554 (2 byte)
I did it like this:
for writing,Tx:AA 90 55 AA 5A A5 01 DE 00 00 05 54 CC 33 C3 3C
for reading, Tx:AA 91 01 DE 00 00 00 02 CC 33 C3 3C
I do it this way, but it does not work.
where am i making a mistake?

I Don't Receive any Rx valueafter send"AA 91 01 DE 00 00 00 02 CC 33 C3 3C" command. For this reason I can't read at 01 DE 00 00 address.
AA 91 <Address><lenght><data>CC 33 C3 3Cdata is not coming to me from the screen..
why could it be?

First, determine whether the screen can communicate. First, try the handshake command AA 00 cc33c33c to determine whether the screen can communicate normally.

There is no communication problem with the screen. I use many commands. but I just can't read from memory.when I send a reading command from the memory of the screen, there is no response from the screen.

Birçok kez denedim. maalesef çalışmıyor .. Bu değerler için benim için örnek komut yazabilir misiniz?
* bellek adresi Kaydetmek istediğim: 0x01DE0000
* belleğe kaydetmek istediğim değer: 0x0554.
Belleğe yazma ve okuma komutları nasıl olmalı?
-yazmak için, Tx: AA 90 55 AA 5A A5 01 DE 00 00 05 54 CC 33 C3 3C
-okuma için, Tx: AA 91 01 DE 00 00 00 02 CC 33 C3 3C
Bu doğru mu ??

The written instruction is correct, and the read instruction is changed to AA 91 55 AA 5A A5 01 DE 00 00 00 02 CC 33 C3 3C
