Ive been looking for a slightly larger display module than the one supplied in the web shop. The standard supply item is a little small and the Mini is a bumpy ride. LOL, driving along its difficult to just glance at the screen and it be in focus, im finding myself taking more time than i should to read the info i want. Some will say take it out the car altogether, well, i want to be a flash git :P
I have searched high and low, phoned a couple of places in the uk, but none will sell just the one, if you want 100 then its not a problem, lol. Give them their due, they were extremely helpfull :) Also not a problem finding the standard size units from the most usual suspects, Farnell, RS, and Maplins
Anyway, looking further afield, i found this in the US http://www.crystalfontz.com/products/2004l/index.html#CFAH2004LTMIJP at $46 plus $28 postage and handling. Viewable area is a little less than twice the area of the standard supply item and available in the blue and the green.
Check and be sure of the sizes on the link above

A blue one is now on order ;D
-
Hi,
Pics!
When it's fitted and working of course ;)
Cheers,
Gavin :)
-
Its arived, and i couldnt wait to get it wired up :D
OMG!!! :D Its huge in relation to the diddy shop item :D :D The PCB width is about the same, but its about 1 1/2 times as long. The veiwable area is huge.
Unfortunetly, i need to source some variable resistors to set the contrast, i used the ones off the shop display, but obviously they are not the right values :-\
This will be mounted on the top in the middle of my new race dash :P I need to make a fibre glass pod for it though ;)
Ongoing :)

Hi,
I like the look of that :)
Have you seen the new one they've done for the MS?
Apologies for swearing :o ;)
Cheers,
Gavin :)
-
Looks great! keep us updated on the progress. I wouldn't mind picking up one of these if you can get it to work. Hopefully i'll see a writeup on here soon. ;)
-
Hi,
Did you not get the bezel they do for that Sprox?
Cheers,
Gavin :)
-
??......
The Bezal is black ;)
Anyway, its sorted, picked up some variable resistors from Maplins and got them soldered up ;D
Resistance value for contrast is 670 ohm and I used the usual 27 ohm for the backlight, job's a good un :D

Have you got a link?

Hi,
Scottie .. You're really trying to get me into trouble here! :o ::)
Shhh .... http://lcdash.wikispaces.com/ (http://lcdash.wikispaces.com/)
I've read it will work with other ECUs, but they appear to only have software for MS :(
Cheers,

The problem with screens is focusing on them when you drive you have to switch your focus from the road ahead to the screen and then back again, dials, lights and simple digital displays can be 'seen' while looking at the road.
Have you seen this:
(http://www.vems.hu/download/v3gui/pdacockpit/PDA_cockpit_0376_m.jpg)
I'm not sure how the dial will show up - it may be possible to improve the visibility with simple high contrast graphics - black information on a white background does the trick in 99% of cases.

That was the reason I wanted the bigger display ;)

Hi,
That looks ace to me Rob, will it run on a full size pc?
Cheers,
Gavin :(
-
Its written for Microsoft Windows Mobile Version so it will only run on a PC using an emulator.
They got it running on some extremely cheap PDAs
-
Hi,
I've already got a PC running in the car, so I'll have to give the emulator a go!
Cheers,
Gavin :)

Here's a link to Windows Mobile 5 Emulator: http://www.microsoft.com/downloads/details.aspx?familyid=EEC33AE3-C129-4C25-ABAA-18E8E842178F&displaylang=en
No idea how it all works though.
-
little bump but what screens are people using at the minute?
that ms one that was linked looks good- have we got something similar now?
-
Hi,
Sprocket is using the large LCD.
There's the PDA setup.
I'll be using Megatune on a dash mounted 12" TFT ::)
Cheers,
Gavin :)
-
Bigger LCD together with non-geek mode is a very cheap dash candidate. I plan this kind of solution for my racecar. Could use some 10,4 inch XGA LCD display with docked small laptop if we get TunerStudio that supports VEMS though.
-
They're doing the Round gauges as displays now (without the Wideband and EGT electronics) which use the AiM protocol to display the values from the VEMS ecu.
-
Yeah, I know that but I'd like to have MXL dash alike thing. PDAcockpit is the closest thing to that, but big LCD display with non-geek mode is much better as it doesn't require additional computer in the car.
-
Hi,
I've seen nice displays that run on can bus. I can't find any info as to weather they got the can bus running on VEMs.
The pins are on the board, but no conclusion on the wiki....
Cheers,
Gavin :)

Rob - this is very interesting. I have recently completed development on a Windows CE touch screen product for security/automation, and want to gauge interest in using it for a dash / tuning handset. Are the guys who did the PDA software interested in sharing it to develop it further?
I am keen to get a prototype working, and then if people like it I can provide the VEMS community with a source of these touch screens?
its a 5.7" VGA touch screen, 12VDC powered so easy to hook up

Hi guys
I think that the Wince would be a great solution because there is many cheep Lcd´s on the marked also I have testing some Navigations 7” multimedia units and it could be great if we have all functions in one unit like radio, navi, dvd, phone, and Vems.
A guy I Denmark has made an application in Windows visual studio (c#) for Ms phone and pda using communication via blue tooth add some pictures.

That looks really great too Peter. I am about to start on my own application but if someone is interested in collaborating it should yield a better result for all?

I can't commit to anything but I have some C++ and C# code that provides a data model for the MegaTune protocol
-
You have been PM'ed regarding code Rob, did you receive it?
-
Might have been lost in the database shenanigans. Would you care to email me directly?
-
Can you send me too?
Somewhere I found a command and data element reference, but i have not found now..
Okay, I have found the D command structure now!
(making a custom lcd with arduino microcontroller board)
Has anybody idea about using SIPR protocol instead of Megatune? I have made some serial logging but Vemstune using megatune D with the new firmwares too...

I would like to think that it was me that made this happen ;D

Hy!
I can't find the wiring diagram for the larger LCD.Is the same as the small one?
Can somebody help me ?
(Sorry for my enlglish)
any ideas? ???
johny.

It most likely is. I got mine from the crystalfonz site, and the LCD has 18 pins but only 16 are used and they're identical to the small one - I just swapped the wires over.
Installed:

Nice! I have the same LCD
but it's not obvious for me becouse the small lcd have 32 pinout and the big one have only 18.
Can you give me the wiring diagram for it?
Like this In phatbob user guide:
* LCD-J1 to LCD-J16
* LCD-J1 to LCD-J3 (2,4K ohm resistor)
* LCD-J2 to LCD-J15 (27 ohm resistor)
To connect the LCD to VEMS (suggested wire colour)
* LCD-J1 to DSUB9-pin5 (brown)
* LCD-J2 to DSUB9-pin1 (red)
* LCD-J4 to DSUB9-pin9 (white)
* LCD-J5 to DSUB9-pin6 (orange)
* LCD-J6 to DSUB9-pin2 (violet)
* LCD-J11 to DSUB9-pin3 (green)
* LCD-J12 to DSUB9-pin7 (grey)
* LCD-J13 to DSUB9-pin4 (blue)
* LCD-J14 to DSUB9-pin8 (black)
Just if it's not a problem for you.
Thank you very much for your help.

32 really?? My small LCD only had 16. The pinout was exactly the same as the LCD guide. The large LCD was the same except the last 2 pins do nothing. Here's the manual, see pages 11 and 12:
https://www.crystalfontz.com/products/2004l/datasheets/1081/CFAH2004LTMIJT_v1.0.pdf

Yes it has 32 pinouts 16 at the top and 16 at the buttom of it. I dont know exactly but outputs can be the same but in two rows becouse the lack of space. I realy dont know.
Thank you for the link! Now i know what to do.
Cheers
Johny

If I remember correctly, the pins at the top are the exact same as the pins at the bottom therefore, in reality, there are only 16 pins. I just used the Wiki diagrams, and the Crystal Fontz datasheet. Pretty much like for like.
