Arduino Library

[hoopstar]

Is anyone aware of a library or project for the arduino that can read/display data from the ALDL connector in real time?

Looking for something for the 424 V8 PCM but haven't found anything yet..

Would be interested to know this as well.

Festy wrote something that was pretty close see this thread viewtopic.php?f=13&t=2195 but ive just been over it a couple of times and I dont think he ever made a public release.

Having said that it shouldnt be hard to write your own. I'd be interested to help. The ALDL data format is known, and the definition can be read out your xdf.

Or you could run ALDLdroid on an android platform.

Antus, that would be greatly appreciated if you could help out - my programming knowledge is a little basic and I am sure others would love something to make the ALDL data easily accessible.

My project (so far) uses three OLED displays all running off one Arduino to read battery voltage, oil pressure, status of the 'Power/Economy' mode and outside temp/humidity. Ideally though, I want to be able to read out other engine parameters (ie. RPM, MAT, MAP etc) and DTC's in real time from the PCM.

This will eventually go into my VK centre console where I've designed and 3D printed a surround to replace the sunglass pocket in front of the shifter. I am trying to make it look as 'factory' as possible.

My problems come when you start talking about integrating the xdf into arduino, so again any help would be awesome..

That is going to look mint Great work

yeah very nice work so far!

Far out! Looking great!!

Maybe add in a SDcard. Then an XDF can be imported from there and processed (Just like what Tunerpro does).

Alternatively, create a separate class to process received frames for different vehicles (VS, VR ect) and hardcode them in.

Depending how its setup, you could then get the newest data like this:
if (Vehicle.DataAvailable == true){
Screens.ProcessToDisplay(Vehicle.Data)}

Nice project, that sunglass holder face plate is neat as

The attached might help get you started reading ALDL data The displays you are using, depending on the library may tie up the arduino for a bit of time so logging speeds get pretty slow.

Here's some Arduino sketches that I found a while ago, it's hardcoded for a specific ECU so would need some work to make it more modular.
If all the I/O you need is a UART and SPI lines for the displays, have a look at some of the ESP8266 modules, i.e. ESP-12E. They're Arduino IDE compatible, have built-in wifi, and are 5-10x faster so have no trouble driving the displays at full speed.

nice work!
