Title: Lcd's
Post by: Seight-v8 on November 07, 2009, 06:14:34 PM
hello all,

Got all my new vems wiring done, and engine is really ready to start (4.6l rover v8).

Just thinking i have some spare space just under the dash i have always wanted to fill with something.

While the dash is still out...i could fit a lcd in the space.

What lcd's can i get in the UK that will work with the vems unit?

just a thought at the mo.

cheers

scott

You could just buy the vems one,

Buy a Vems Round. I have always found the LCD problematic, they crash un expectedly and require an ECU reset. I have just shortened the cable, fitted and RFI choke and grounded the screen on the cable to see if it makes any difference. For three years I have had issues of one sort or another with the LCD, but I have stuck with it. I will be ordering a Vems round or two soon.

I take back my words ;D

After grounding the screen on the cable and fitting an RFI choke around the outer and doubling back through it, i have not been able top get the screen to crash after 350 miles in one day :)

Now if only the lag would go away in the 1.1.x FW :)

I am developing an arduino based custom lcd display (and maybe logger) which connect to the vems serial port, Maybe it will be cheaper solution than vemsgauge and will work older firmwares...

I will take:)
I have some remained shop post terminal lcd with nice big characters (2*20), but it works with any hd compatible lcd char display. And arduino has some library for pixel lcd-s too. Very flexible platform:

That sounds very interesting!  Any idea of an ETA as of yet?

There is some picture, bulit into the original Pos display case for testing:

Some new development:

added Adafruit Data logger shield with real time clock:

So displayed datas logged in sd card with timestamp, next week we test in car on the Hungarian Drift Challenge. Now it works with 1.1.27 fw version, 9600 and 19200 baud with 3 display mode:
one gauge with maximum value store and bar diagramm
two gauge with bar diagrams
four gauge

You can change mode and instument gauge with button, and change communication parameter and supported fw version (code is suppport 1.1.7x but need to test it.)
