CanBus for Beginners - Super Simple

Don’t think anyone has worked out button for the Deutz.

As Andy has there in his reply is what you will have to follow to find the CAN button.

Otherwise your options are:

  • select “none” as switch option and use the tablet button/steering wheel in bottom right corner of tablet.
  • connect your own push button to the PCB steer switch input and select “button”

Okay thanks for all the help and advice, I will probably use the tablet button to get setup and started then look into getting the armrest button working in the winter when I have a bit more time.

Are any BOM and CPL files available online for the AOG_CAN_TEENSY4.1 can bus board?

Hi Stephane

Do you have a picture of steer connector and location?

Did you find any inputs for this bus within the cab?

Is it this?

Thanks

Hello

This is the connector X16g, ISOBUS (can4) and WK-BUS (steer) in this connector

Error in CAN_All_Brand.ino

Stephane, thank you so much - that’s incredibly helpful !

Just to be clear, as I don’t have much time tomorrow - this connector is as detailed in the pink on the diagram?

This connector are x16g in the diagram

Hi all

Out at the dealers today, we got nowhere with this. Tried all 3 buses on x16g, especially wkbus, and no steer codes to match the INO at all. Even using the flow view in savvycan, nothing looked like a WAS. This was with the valve engaged BTW, and even with it steering in the factory SBAS autosteer.

Any suggestions?

Didn’t go in via the roof as wkbus was in cabin, confirmed with the dealers schematics. Logs here: https://github.com/lansalot/FileDump/blob/main/valtragen5logs.zip

Hello, Google traduction

For the guidance system to work, there are several conditions to respect:

  • Validate the guidance
  • turn the wheel to the right or left to receive the frame 0x0CAC1C13
  • move forward with the tractor, otherwise no effect on the wheels
  • engage guidance, reception of frame 0x18EF1C13 (byte[0] 15 byte[1] 96 byte[2] 01)
  • Send frames 0x0CAD131C with curve in byte 0 and 1 and 253 in byte 2

You had to use X16G, pin 9 a 10 (WK-BUS) for steer

Thanks, we did pretty much the same. The one I was in was the one with all the screens, command joystick, etc. The steer valve, I believe, is enabled on the arm and this brings up a screenshot full of options, one of which us a steer box you have to tick, and autosteer-engage button is beside it. As this one was steer equipped, there’s an auto-steer option on the monitor too that brings up your fields etc but I presume that wouldn’t be there unless unlocked.

So, it had all the toys, but no sign of the AC/AD drive codes. Full captures at the link above. Going to try a T.175 tmrw to see if thats any different.

on valtra T214 I think I have to found X11C connector

Hello,
I would like to equip a maxxum case from 2017 with agopengps. here are some photos of the steering solenoid valve and connectors.
Do you think I can do a canbus assembly?



I believe it is analog like ke this. Case IH Puma 230, autosteer ready

Hello,
I would like to know if it is possible to connect AgOpenGPS via CanBus on 2 Tractors which are not autosteer ready : New Holland TG285 (2003) and Claas (or Caterpillar) Challenger 55 (1998). I have the electrical schemas but can’t easily find if the steering and related hydraulic valves could be piloted via CanBus.
Has it been done already by some here (and if yes, how) ? Do you think it is feasible before I try looking into CAN data to find out ?
Thanks

if not ready for autoguiding = no valve
2003 and 1998 not canbus
But someone will confirm

Thanks for the reply. I can confirm both models have a CanBus (can be seen on their Electrical Schemas + I changed the CanBus terminators on one of them), but question is if it can pilot the steering and/or the valves directly. Thanks.

Have you hydraulic valve?

Yes on the TG285, there is hydraulic valves.
For the Challenger 55 it is another topic as it is a tracked tractor, so it needs to pilot the differential steering inputs to manage the tracks speed as the steering wheel does.
This is why I think, for both tractors, that just piloting steering inputs from the CanBus would be the simplest approach, to just mimic what the steering wheel does.

Do you have a picture of the steering valve on the TG so we can see if it’s CAN or not?

The Challenger tracked is added to the Teensy code and works on newer models, you can try on the old model and see what happens.
