It’s a 2021 T7 autosteer ready.
Yup thats the green canbus plug.
You can either connect there or to the 40 pin connector behind the passenger seat. Pins h and j from memory
You will need to access the h menu to turn the autosteer valve on.
Depending if its had autosteer on it before or not, if not you will also need to do a WAS and SPOOL calibration which then calibrates then sensors and the steer valve and hope its all working and you get no error codes
Yes, how can I “open” the calibration? The tractor has a screen but it has never has any autosteer. And another question is which program should I flash in teensy from configomatic
Thanks
You’ll need the calibration plug to access the h menu, its all done through the dash screen. You will also need to do a valve calibration if its not had autosteer on before.
For the teensy firmware i use it from the boards repo, its the aio v5 canbius modified sketch and i use arduino ide to flash it
Youll need to go into serial monitor and select brand 2 for nh and also select P for panda gps.
Have you looked here.
The calibration procedure is also there i think. The WAS and SPOOL calibration can be a bugger to get started
I have a T5 Dynamic Command (2023) that Im working on putting AOG on, it’s got the sidewinder armrest and the steer button on the joystick
I’ve tried sniffing the CANBUS, I got a good bit of data but could not see the button presses, It is not auto steer ready. But it has the steer button.
I was connected to the green plug behind the seat, if I connected to the black one it threw up an error on the dash with lots of beeps, it was not happy that I was connected to it.
Just want to make sure I haven’t missed anything before going down this rabbit hole too far.
My plan b is to use a spare button on the loader joystick instead to trigger it.
I have put AOG on one tractor in February, spent one day using it. Now need It in the others, I don’t want to go back to manual GPS!
The engsge button is on the black plug on the pillar pins c and d for canh and canl
You will need the CANBUSEnable firmware which is not on configomatic
This will only work with a valve or motor added i think

Planning on using the keya motor, and that’s also CANBUS, so likely that’s a non runner for me then.
That would be nice to use i agree
You’ll need the aio board with 2 canbus chips then alter the keya firmware to add the 2nd canbus

Thanks for that info, If I end up putting AOG on the 3rd new holland, I’ll do that.
Already have the board from agopen.shop (I think its the 4.5 board) on the way and hopefully It will be here before the long weekend and i’ll have a chance to put it in before we start planting.
Will be on the todo/need to learn more about list.
Edit:
I Possibly could make a machine board using an esp32 (eg a lilygoCAN ) board which i have a couple of, and use that to send the steer signal. I will run some tests first.
Went and had another poke with the canbus sniffer on our t5 dynamic command. It has the same cab as the t6 and t7
When I connected to the black one on the pillar it threw loads of codes on the dash and a few beeps. It was not happy until I unplugged it.
I had previously connected to the green one behind the seat and got data but didn’t see anything changing when I pressed the steer button. I did idea using an esp32 to do the can communication and have built a prototype board with a button (and learned a lot about the PGN’s)
Anything I’m missing regarding connecting to the black one on the pillar?
(Ive also found out that the black plug and green plug is different, as i had went out and got ones to have)
Try pins h and j on the green plug for the steer button
The pre 2018 the steer button was on the black plug

Thanks
I’ll look again, not seeing them last time doesn’t mean they weren’t there.
Tractors a 2023 model, I did get data from the green port before, anything in particular to look out for
Hi, very interesting read!
My next project is to link up my neighbours T7 to AOG via CANBUS.
Along with the AIO v4.5 Micro board, just a quick query on what else I might need.
Teensy 4.1 I take it this can work with CAN without any other shields?
does it have to have the “ethernet chip?”
Cytron MD13s do I need this?
The teensy needs the ethernet chip if your using ethernet connection to the tablet
No you wont need the cytron for the canbus vechiles
Tractor will possibly need the steering controller turned on and calibrated in h menu if its not had steering on before
Great thank you.
Will I need the cytron for hydraulic steering control then?
Thanks
Is your connecting to a hydraulic valve or phidgets type motor yes you will
If your connecting via canbus no you won’t

Hi, is this file called “Autosteer_AOGv5_Teensy4.1UDP_SteerReadyCAN_AIOModified.ino”
I opened it in IDE and uploaded it to my teensy, but had no GPS when I used that one.
I went into service mode and picked 2 for New Holland, then again to pick P for panda.
Still no GPS. am I not saving it correctly or is there something I am missing? IE when I press the P and hit enter, is there anything else I need to do before unplugging?
If I flash using ConfigOmatic using the AIO 4.1, I get GPS and steer, but this is no good to use when connecting to a steer ready tractor via CANBUS
Thanks
Yeah thats the right teensy firmware
Sounds like your doing it right. After entering brand 2 you then need to open serial monitor again and select P
If you run serial monitor again check its actually selected your changes in the play back list
I think I done that correctly then.
I will double check it all here.
Strange that it all works ok on the AIO v 4.1 firmware, but not on the one listed above.
Will try reflashing it again. Hopefully will have better luck. Does it make a difference that I am using the v4.5 micro and not standard?
It’s always P for the higher baud rate and not p for smaller?
The board itself is no different so same firmware
Its aways P if your using 460800 baud rate as thats what most teensy firmware is set to
Try flashing the f9p again with configomatic
