Older code wasn’t returning the pwmDisplay (I think) value back to AgIO. Pretty sure I fixed that in later revisions, but if not I’ll do it when I get a chance.

Thank you and good luck always.

I have two questions:

  1. What is the current recommended Keya steering package model for a tractor?
  2. Are the units of measurement used in the Keya Adapters chart in millimetres?

Both answered here: Keya · AgHardware/Boards Wiki · GitHub

I’ve got the keya + v4.5 board working - great!

According to the Ampseal pinout pin 7 should be Switched 12V output when autosteer is enabled - I would like to use this to light the LED in the steer switch, but there never seems to be voltage on pin 7, is there a setting to enable this?

Thanks

No setting in AOG. Don’t recall touching anything for that in the Keya branch, it was the lightest of modifications to add Keya support.

I think @BGunics has modified code to use pin 7 to light up LED.

48

Yes I did that.
You can find the hex here:

Sorry for late reply - @BGunics sounds just like what I want - but am a bit confused…

Is it the AOG-Keya-CANBUS_lazykickoff95.hex one that I should load to my teensy? (ie the most recent one)

I assume I can load it as per the teensyflasher instructions?

In this version, does pin 7 output 12v when steer is enabled - or some other voltage? (my button LED is 12v)

What is the kickout rolling average all about? (or perhaps there’s some documentation somewhere?)

Thanks

I’ve not documented it.
Basically the amp meter of keya starts to report values and I’ll do:
current = current * 0.95 + reported * 0.05

Which greatly eliminates the spikes.
also when engaged it’ll take some time until the value gets close to the kickout % set in AOG.

OK, thankyou.

I suppose the answers to my other questions is ‘yes’?

Is there a source code file (.ino) available of the non-rvc keya teensy firmware on anyones github repository? I can locate a source code file for an older older keya firmware version, but I cannot locate one for the most recent version. A hex file is no use in my case since I need to change a few parameters in the source code to get it playing nicely with my system. Thanks

@BGniics - all works perfectly - LED now works as I hoped it would and after readjusting the settings seems to be steering much more consistently than before - so thankyou very much.
