graphics lcd interface
Hi,
I'd like to interface a Z80 cpu to a monochrome LCD display through a dual port sram.
The LCD is a 320x240 graphic display but I just want to use it to display 40x25 characters which will be stored in the dual port sram (1KB).
I'm thinking of using the following hardware: Optrex F-55157GNF-LW-ASN display, and Cypress cy7c130 dual port sram but open to suggestions.
What would be the best way to go about doing this?
Please would you give me some pointers in the right direction or any sample circuit designs would be very helpful.
Thanks.
