ALDL LCD Display

[BennVenn]

Hey, update. They arrived last month, just need a few days spare to solder, program and test them. I'll put them up in the store when they're ready.

I'll include a pre-prepared SD card with the instructions and config file on there to get you started. I don't plan on offering support for these, all the basics are in the instructions, anything that isn't covered i'm happy to help with. Please use ECU 5v to power these - either from within the ECU or splice into the MAP/TPS sensor 5v reference.

Hi there, is there any version of this thats compatible with a vs commodore v6?

[BennVenn]

I'm not sure about the VS, maybe somone in here knows if they support '808 style 160 or 8192 comms?

[vlad01]

VS is high speed.

[BennVenn]

5 displays added to the store. I'll add more if / when they sell out. There is NO support offered for these as they are sold at cost price for enthusiasts. If something isn't clear, ask and I'll answer when I can.

They will be shipped in 8192 (OSE12P) mode, with a micro SD card loaded with an example Config file and manual. You can bridge SJ1 to put it into 160baud mode, or SJ1 and SJ2 to put it into 160baud debug mode. These screens are intended for use with OSE12P

160Baud support for stock ECU's ('808) and 8192baud (5v logic ONLY) for '808's running updated firmware (OSE12P etc).

manual.rtf on page 8 here viewtopic.php?p=120310#p120310 describes the config file and how to get the information needed to configure the display from the ADX you are using to log the car. It should be compatible, if you have the understanding to build the config for the VS, but there will be more data on the VS ALDL bus than a stand alone and I don't know if this device is designed to share the bus with other modules as I think in Ben Venn's case it was only the ECM and this module.

If you know the frame formats for the VS, it'll filter them out against the noise. If the VS ECU puts data out without a request, you can put the device into passive mode so it won't ask for frames. I think the biggest unknown (to me) is if the VS uses a single wire for TX/RX at 12v logic, or if it has access to 5v ttl RX and TX pins. You'll need the latter

VR onwards are all 5v single wire ALDL.

Theres an interface circuit here: viewtopic.php?p=95557#p95557
Which works well

[BennVenn]

if it's 5v logic single wire then it will be electrically compatible. Tie TX and RX on my pcb together and connect to the single wire 5v logic signal, wire up gnd and 5v and the rest will be up to the config file. If there is a lot of chatter on the bus, i might need to update the firmware to wait for a break before requesting frames, or send the silence command (I noticed a option in Tunerpro to do the same)

[antus]

The VS should be reasonably quiet but more than zero. I think security, SRS, ABS and BCM are on there. But the electrical properties will also carry through to VT and later and on those ones there is a lot of chatter on the bus as some of the cluster is driven by ALDL. For a permanent gauge you probably dont want to send the silence chatter as that usually triggers errors, which is OK during a flash process or tuneing, but not a good fit for normal operation of the car. For those models, there might not actually be enough time left for the Mode 0 frames together with the normal vehicle communications, so in that regard VT and newer is probably not a good fit, but VS should be OK.
