I built this - takes a couple of potentiometers (one for WAS and one for pressure feedback) to test:How are you guys bench testing your boards? I have the AIO GPS+Steering ECU V2.4 board. I flashed the teensy with firmware "autosteer_sps_teensy_v4_1.ino.hex" and have a green led, no middle led, and a red led lit. I hooked up the WAS to pins 1, 2, and 3 from the ampseal diagram but not sure if that is correct as I do not see any change via the AOG software.
Some photos, and info on how you have it wired would be a good startHi, I’m currently trying to test my setup on a bench and I’m having a bit of trouble with my WAS, I’m not sure it’s working properly because on AOG it’s saying it’s stuck at 30 degrees when I move it. I was wondering if anyone else has had this problem and if they could help me ?
Thank you
Well I’ve been talking to @Andy26 about it as he made the wiring harness for me and it seems like it’s wired properly (all to the correct pins) so I‘m just a bit stumped on what it could be apart from the WAS being faulty.Some photos, and info on how you have it wired would be a good start
You need to check the red wire on the WAS plug is outputting 5v, if it is, then open up the PCB and put the multimeter red probe on pin 2 and black on pin 4 they're labelled on the top of the PCB.Well I’ve been talking to @Andy26 about it as he made the wiring harness for me and it seems like it’s wired properly (all to the correct pins) so I‘m just a bit stumped on what it could be apart from the WAS being faulty.
Looks to be very smooth and keeping to the line very well, judging by distance off line.My Keya CANBUS code in action here, made it all the way over to Australia! Ryan took it and used with a UM982 instead of the usual F9P to create this, and it holds the line well eh? Can any factory system beat that?
Yup. 2 power, 2 canbusLooks to be very smooth and keeping to the line very well, judging by distance off line.
4 wires, to Keya wheel that's it?
The WAS or wheel angle sensor that everyone usesYou need to check the red wire on the WAS plug is outputting 5v, if it is, then open up the PCB and put the multimeter red probe on pin 2 and black on pin 4 they're labelled on the top of the PCB.
With the wheel angle sensor arm at right angles to its plug, you should get 2.5v or -2.5v or close to that, move the arm a little and retest the voltage should vary.
Have never seen one that does current - the Claas, Case and MF ones I've looked at directly are 5V varying voltage.The WAS or wheel angle sensor that everyone uses
How come it's a sensor that feeds back voltage based on angle, industry uses 4-20 mamp
More curiosity I'm asking out of as won't be going that far with my setup
Same all been 5V type.Have never seen one that does current - the Claas, Case and MF ones I've looked at directly are 5V varying voltage.
