address bus of 8051
Hello,
I have worked on 8051 from Last 4 years.At that time,I only used
Peripheral Mapped Interfacing.
Now I want to Memory Mapped Technique for Interfacing using
Address and Data Lines.
I have made one Test schematic as Attachment.For Operating two LCDs using
Same Data Bus and But Different Address.
But I could NOT Incorporate /RD and /WR Signals for LCD_EN.
MAY Be with AND or OR Gate IC Logic?
Can Anybody Suggest you how to implement /RD and /WR and how it work for LCD_ENs?
Which AND or OR IC NO. I have to needed?
