Where did you get the displays because I would like to try ?

I bought mine through a crappy GSM webshop here in the Netherlands for 29 euro each (5 displays total (hey I got other projects aswell)). The kind of shop that makes you wonder wether it's illegal or not... :roll: But they are new and they work. Just make sure they can deliver the right version if you can only use one of the two controllers.

Jelu sells the right ones guaranteed. It's pricy like Henri said, but you know what you're getting. With some other shops that's always a guess.

Yup :D

hi ,
hey henry and zotti ,how do you come to know that the colour LCDs with PCF8833 controller are being used in nokia 6610 and 7210.
how can i come to know the controller information in other nokia colour LCDs. Is it available on nokia site :roll: ???

thanks,
Pravin

Can we expect a collaboration between the two greats of LCDs (Zotty and Henri of course :D ) to bring us a single great program for both winamp and system stats?

It's just the sheer luck of running into the information. Nokia does not give this kind of information, so I'm guessing these things are put on the net by someone working at a servicecenter or something like that.
Most of the time I discover hard to find pinout/controller information by browsing through forums, even Chinese/Japanese ones. And rarely by browsing product trees of LCD controller manufacturers to just see what they have and just guess which controller/commandset might be used.

I don't exactly have an answer ready, but.... the thought has crossed my mind before. Make some sort of kickass MP3/OGG plugin for LCDInfo. But that was just a private thought, Henri does not know this ehehe ;)
On the other hand I've also thought of kicking Winamp out of the whole project, and make my own music player, specialised in outputting info to a display. And other things... so you might say there's a lot of thinking going on..

I'd be very happy to see a LCDInfo plugin made by a specialist like you Zotty. :D
But on the other hand I understand if this doesn't fit in your plans and you prefer to put your time on something else.

I once thought if it was somehow possible for LiQuiD-MP3 and LCDInfo to cooperate and use the port in a civilised manner. I think it would be possible but it would require some work on both programs to give up the port and then re-initialise the display again to it's own settings. Also they would need to communicate with each other to know which one has the turn.

There should be a "standardised" lcd driver layer that other programs could then use for outputting to the display hardware instead of every program having it's own drivers. I have thought of something like this but it would take some work and time and without support from other programs and developers I don't think it's worth doing all the work.
But this way writing some program for different lcds wouldn't require handling the hardware details and more than one program could work at a time.

hi,

i'm currently working on a portable mp3 player based on an atmega128 and i'm wondering if it would have enough power to handle such a color LCD, that would be great :)

by the way, thanks for your posts, they're pretty helpfull concerning the wirings

BoberM:
Thanks for the link. That should be a good price for the display.

wedge:
AVR should have enough speed to handle something like this. Of course in the end it depends of how much other things the micro should do at the same time and how complicated things you want to display.

ok thanks Henri, that was what i thought, but before buying one i'd prefered to ask :)

in fact the avr will have to read a stream from the hard drive, handle the lcd and send the mp3 datas to the decoder chip... the only bad thing about this is that i have to share the spi between the mp3 chip and the lcd, but i think that will be ok...

now i've just to buy one and start making my own tests and write a library to handle the lcd

I finally got fed up with my laziness with this project and took my old FTDI board and wired it for 3.3V IO. Also soldered wires to the Philips display pads and connected things together. Something I noticed was that the voltage in the FTDI pins was about 4V and not 3.3V like I expected. But anyway I got the display working and my first color fill only took about 10 minutes to fill the entire screen ;) Guess I should have done some calculations of the bit bang rate instead of just putting a random value there.
Also the backlight is not yet connected so I need to figure out something to drive it.

Next would then be some optimisations to the speed and closer look into the PCF8833 datasheet to see what exactly can be done.

Hi all,


could someone point me in the right direction with regards to the initilisation sequence of the PCF8833?

RESET -> BSTRON -> NORON -> DISPON

I'm getting nowhere!


regards,

Did anyone already buy a LCD or a connector at this shop?
There are no terms and conditions on their page and they also ignore emails...

I bought one lcd and connector from magboss and received it.
I´m from Brazil.
The LCD is Epson and connector is very small not it's easy to solder. :(

Best regard

I noticed there are two different products:
"Original LCD Mobile Display for Nokia 6100 / 6610 / 7250"
and
"Original LCD Mobile Display for Nokia 6610"

Which one did you order ?

If I had to guess from those I think the "6100 / 6610 / 7250" display might be Epson and "6610" Philips. But this is just a guess and I'd like to know which one you got ?


DaveE:
Have you already got further with the display ?

How much were the shipping costs?
How did you pay, via credit card?
