Hi there!
Attached you can find PCBīs for adapting the famous Nokia 3310 LCD to a 5 Volt system. Furthermore the PCB is compatible to breadboards and experiment boards and so on and so on. Youīll find all the features in the attached file.
Unfortunately the only order chart I got is from reichelt.de (as Iīm from Germany and itīs the best electronics seller here). If someone could adapt this to digikey or similar, this would be awesome! 
If you find any bugs or somethingīs missing, pls let me know!
Besides: I wouldīve liked to post this as a complete project (it will get lost in the forum in letīs say one year for sure) but as you might know there is neither a "Type" nor a "Compiler/Assembler" entry which is suitable for such "only PCB" projects. Maybe you could introduce a new project type for this? I do think this could bring the redundant work down for many people! |

Nice project. I too think that AVRfreaks could use a hardware project entry method.

Hi pay.c (and Tom of course )
Indeed very nice and thanks for sharing this.
I asked Eivind to add the HW-only possibility in the Project-area.
Cheers

hi pay.c
thank you so so so much i don't think this topic will ever get lost as google is keeping eye on it 
----------
EDIT:
pay.c i really want to thank you sooo..... much.. don't have words i mean after burning 2 LC displays i found this..  thank you so much..
one question.. i don't have 220ohm resistor, rather i have 1K resistor.. will this do the job? in the PCB? and work with 5V? |

pay.c would you possibly have the Eagle footprints ? maybe ?
It's a great project, thanks for posting it. |

@ajay: I did not try that at all, but anyhow, it *should* work. The resistors are just limiting the current running into the LCD controller, so 1kīs should also work well at not to high SPI speeds. If you run into problems (what I donīt think) just lower the SPI speed and everything should be just fine.
@buserror: Attached youīll find my own Eagle library (I had to zip it so the forum accepts it). Just donīt mind all the other stuff, itīs some kind of my "working library". Itīs just darn uncomfortable in Eagle to get something in a library deleted or copied, so I just give you the whole package. Anyhow both Nokiaīs do work. btw: I use Eagle 4.11 light if there are any problems opening it.
BIG Thanks to all for your regards. Itīs good to know that your work is actually used and not totally useless. |

Errrrrrrrrrrrr, say, did you actually read this thread? I am doing that and itīs working fine, just download the file...
Or did I miss something?
In other words: The PCB brings the 5 V down to 3,3 for VCC (with the two voltage dividing resistors) and the other (logical) lines donīt need downscaling as long as you use the resistors in front. |

I know what you did in the PCB
well i was asking something else is ok!
thank you so much again for the PCB |

| Hmmm, did you mean VCC 5V? Running the LCD on 5V VCC and 5V logic levels? I didnīt try that at all as I am afraid youīll fry the LCD with the time. It should work for a short shot, but over time youīll perhaps fry the controller. Anyhow, as you get those LCDīs for nothing (4 Euros or so) -> just try it and tell us. |

First off, sorry for dragging up a thread over 4 years old!
I've just made the PCB and connected it up. At one stage I got some text to appear on the screen, then the next time I powered up it didn't come back. It could be a loose connection or something.
Anyway, my question is: why isn't reset connected? The datasheet says:
Quote:
Immediately following power-on, the contents of all internal
registers and of the RAM are undefined. A RES pulse
must be applied. Attention should be paid to the
possibility that the device may be damaged if not properly
reset.
Could this be my problem? |
