Hello to everybody in this forum
Actually, I am working on the led matrix board in which i am interfacing the AT keyboard using 89s52.Whatever I type on the keyboard must be displayed on display continuously as a string.
Now the problem is, I have to store the the character that is pressed on the keyboard
As 89s52 has only 256 bytes of RAM i am not able to store store less than 256 characters.
and next thing is we cannot update this into the ROM as well during the run time.
Now the only option is i have to use external memory.
so any one can suggest me which memory can i use for this purpose so that i can update this memory with the new strings whenever i need.
thanks
