Diy Haldex controller........Haldex Controller taken apart with pics

Thanks

I'll order one of those and two buttons so I can make a mount up in the dash where the stereo would normally go

 

Great idea. I may have need of something like this in the near future. I have messed around with an Arduino a bit but am not much on programming them. I managed to connect a display to it and get it to scroll text and a few other bits.
The adafruit is a kit so requires assembly, no great hassle but takes time.

Anyway would a 16 x2 I2C display like this

Work in a project box like this, black of course.

Then wire the I2c display back to the arduino and the switches as seperate wires using something like a 9 pin D type plug and socket.

The temperature of the oil in the Haldex is also used as a correction factor in the position of the stepper motor.With the viscosity of the oil changing at different temperatures the calibrated opening positions will vary.

A slightly cheaper motor driver. not a lot in it but it's the same part. Of course if you were to go through aliexpress you would probably get all the hardware for 10 it's that cheap, but then takes forever to arrive some times.

Keep up the good work.

 

Have you read this from the start? Lol think we have covered those items

I've made a blank to fit in the stereo space and will fit the I2C LCD in that with a couple of buttons that I can reach hopefully once I'm strapped in the seat!

 

We haven't covered the correction of the stepper based on oil temperature. It's not something I think we need to do though, as our control isn't fine enough for it to make a difference.

Back to the display/buttons question.
The reason for me looking for a display with buttons on is that I know the code will work, and there's less wiring to be done.

I don't mind writing it to work off buttons that are connected directly to the Arduino, but it does mean long wires from the display on the dash back to the Arduino somewhere in the car, along with the dash comms wires.

So, which one shall we do? Buttons on the display, or separate buttons?

 

Personally I think two separate buttons ??

 

Buttons it is. I'll sort that this week, including the wiring diagrams.

Is the code going to be publicly available, or are the club going to be able to make some money from it?

 

I think something for the club or it will just go viral! Lol

 

Good idea

Easily done

 

Hello forum

Today just discovered rear wheels were not working so after some investigation I found that my china TB6560 board was not working.
Just ordered a new one.....will try to understand what happen to the old one

 

I'd been waiting for the I2C LCD screen to turn up. Turns out I forgot to order it. lol It should be here on Thursday.

I've updated the code to work with separate switches, which works with the old screen. Hopefully updating the code to work over I2C won't take more than a few minutes, and then it's ready.
I'll draw up a wiring diagram, and then we'll need to sort out hosting the code and wiring diagram.

 

Thanks Alex

 

The code is done. Here's a picture of the wiring:



Is that clear enough? I couldn't find a Fritzing of the stepper motor controller, but it's pretty clear what goes where.
I'll add all the pinouts to the final post in the members section.

 

Good morning boys

Hi Boys

Any news with your Haldex projects ?

My research and development for the correct settings still continue:

I've just realised I forgot to create the thread in the members section with the code and diagram. I also need to return the Haldex unit.

I'll post the full code, and the wiring diagram on the previous page, along with a couple of pictures. Is there anything else anyone thinks should be on there?

 

Nice work Alex even though I'll never use it lol as 16v doesn't need 4x4 lol

 

hi sparrow

are you going to publish the thread soon ?

many thanks
