fitted a canbus board to the 724
this morning, switched on task controller in the vario terminal and set the autosteer activation on the small go button on joystick,
drove across yard and it activated agopen
pulled down to a field to further tune the settings then the button wouldnt work again
did some quick googling and youtubing on my phone but no luck in sorting it out there.
agopen works fine by pressing the screen steering the tractor properly.
pressing the autosteer button on the console in the fendt does nothing bar make the light flash 8 times, same thing pressing the go button on joystick.
To engage via that auto steer engage signal it is done via ISOBUS.
For the ISOBUS to talk to the Teensy it must first claim a address for the Nav controller, in the current code this is only done at startup so make sure the Teensy is connected to the ignition key so it starts after the tractor.
On that model of fendt you can adjust the canbus and isobus speed messages, would these need to be set to something different to talk to the cabus agopen board or wouldn’t this matter at all
I had one that wouldn’t work with the isobus engage message. I found the engage message was different than what was in the teensy code. Once I changed the code it worked perfectly. Would have to look and see if I saved this somewhere.
Looks like I did save it to my github here if you want to try it.
That’s odd. I loaded it in a machine yesterday and it fixed the engage not working from the TI problem.
You do need to have isobus on in the vario terminal and configure the TI sequence for one of the buttons to have the engage in it. Also need to have the steering valve enabled on the armrest, that caught me out for a minute after I had restarted the tractor. Sequence was running on the go button but nothing happened in aog, valve on and all worked.
The software on the fendt in question was last updated in 2015 so really old software.
There is a settings page (but cannot remember how to find it) where yoi can alter the canbus and isobus speed messages, would this have any bearing on the problem?
The settings page you talk about can have an effect but only if isobus was turned off.
I do remember hearing of a problem with the engage not working with topcon some years ago. Aparrently Fendt changed software and then the engage stopped working then topcon changed there software to suit and then Fendt changed there’s again. So the software could have something to do with it.
If you got a canlog from the isobus when you try to use the TI engage then wr can see what the engage message the fendt is sending and then add this to the ino.
