Hi people...i tried to find any kind of simple interface between S08QE (3V) and LCD Module (5V)but nothing. Can you tell me about any AN or circuits?

Added p/n to subject.

Hi... I ever use this simple circuit to interface from 3V out to 5V in

fast diode 4148
resistor 10K

Hello and welcome to the forums jlflorio,

It's all here in the forums you just need to learn how to use the search facility here (or even use google, restricted to this site).

This previous post by me seems to answer your query exactly.

Hi,

   Have you considered the 9S08LC60?  It has support for a segment based LCD. 

   Just a thought,

Hello,

If you are using one of the common alphanumeric LCD modules, with either 4- or 8-bit interface modes, I suggest you check its specification for digital input switching level.  You may find that a 3.3 volt swing from the MCU is adequate, even though the LCD operates from 5 volts.  To avoid any possibility of return data from the display, and a voltage mismatch, you would need to set the WE pin for continuous write mode.

Regards,

Mac

Well, what kind of LCD? Graphics array? 1-line? 2-line? 4-line? 640x480?

There's a lot out there.

But if you're looking for something simple, you STILL have to pick your LCD first. If you want something just to display a line or two of text at 16 or so characters, there's simple 4-bit interfaces. I've seen 4-line with 40 characters that still can use a simple 4-bit interface.
