Hello,
I am new to FPGAs and LCD devices. I am trying to interface an LCD device with a Spartan 3 kit (LCD module - 2 line-pre connected in it). Does anyone have a basic VHDL code to display a single character / word on the LCD panel. I am finding the codes available here and on the net complicated to understand.
Also, what is CGRAM and DDRAM in context to LCD devices. Can one read data also from the 2 line LCD devices. Are there any hex character codes for every character to be displayed on these devices.
Thanks,
Emma Good.
