Graphic LCD with ATMega16

atmega16 lcd

Hello!

I would like to connect a graphic LCD, (datasheet here), using the controller SED1520 (datasheet) with Atmega16. I've found quite some information about LCDs using the controller KS0108 (datasheet) and now I'm trying to notice the differences between the two. I don't really see any big differences, but I'm a little confused by the inexistence of the pin E (Enable) from my LCD. From what I understand from the controller datasheet, I see no need for it, but I would like to hear the opinion of someone more experienced than I am.

Also, I'm not really sure how to connec the RES pin. Is it ok to wire it to Vcc?

Thanks for your time.

hi liv

E for enable ,my 128 x 64 ks0108 wont function without this pin connection

the res/reset pin you can tie to ground providing your source does'nt use it

what language/compiler you use ?.

Hi MrChips, thanks for your reply.

Yes, the KS0108-based LCD's need this pin, I'm just simulating in Proteus with one of them, but I'm not sure about this one I have.
I'm using WinAVR that includes the GNU GCC compiler, and ASM.

hi liv
so do you intend to hardware ks or just to simulate with proteus ?.

i use codevisonavr ,i find it much easier than winavr but appreciate cvavr does generate alot of functions the coder should really learn.

i attach for you pascal stangs library ,very good examples inc ks and well commented.

Well, I'm also intending to hardware it. I've put all the pieces of the puzzle together, so I'll go for it very soon.
Thank you for your help, MrChips.

excuse me,
Hi MrChips,
i use CVAVR too.,. can you help me about codevision - ks0108 library?
Is your file (avrlib_1410,zip) can be used in CVAVR ?
I'm using port D for lcd WG12864C ( ks0108 ) and port B to the push button.
Thanks ...

Sory, for my bad english ...

No, If you want to use it in CVAVR, you have to modify the code little.

why do I start a modification?
is there any library that is ready to wear using cvavr?
