Not getting WAS signal into AOG

Hi,
I’m running through a strange problem.
With a multimeter I can see that on the ampseal I get the values from the WAS, correct values. But inside AgIO the steering column is not green. Yesterday when I first connected the was, it worked. Today not anymore. Any ideas ?

What board and was do you use? Is it showing nothing or green all the way to left/right?

Micro v4.5 . The WAS is the standard bmw/Land Rover one. I get readings up until the ampseal. But here it’s not becoming green.

Have you done “electrical validation”, check if 5v is 5v everywhere it needs to be?
What problems I faced:

  • ampseal terminal on wire didn’t go all the way through the hole in connector and didn’t make conntact.
  • I had trouble monting the AIO board in a 3d printed box(it was very tight) so bending the board damaged inner layers of the was traces

Yes but look, I’m measuring after it. So no issues with the cables going inside. 5v everywhere. And yesterday was working.

I think it’s either something fried that converts the signal or something related to COM port missing but no idea where to look and what to check

And it’s not even showing red when PCB is off

You can use the serial monitor ( Connect your Teensy to Arduino IDE) to check for ADC detection!

I see you put measuring probes on pins 1(5v) and 2(was_high) since your black probe is on pin 2 it shouldn’t read negative voltage :confused:

Edit: its actually pin 2 and 3… can you measure black on pin 4 and red on pin 2?

Red on pin 2 and grd on 4 I get correct readings from 0.39V to 4.56v when I turn wheel in the other direction . Teensy flashing red fast. Tried to flash again the software. Doing the same


Don’t know how to read this though.
Any other help please?

Teensy shouldn’t be flashing red. Have you got another Teensy you can try or buy another? Try wiping it and reloading the configuration files again

I think it should, every time panda message is sent.

Than theres definetly something wrong on board. Do you have a spare board? Move all the parts to other board. Or you could do some checking and measuring. Check if ADS115 is fixed in place or it wiggles. Was_h R53 resistor goes to ads1115 you could check if its 1,5kOhm. I know ads1115 is so tiny but should check if it gets his 5v supply. Do you have easyeda, open the schematics and follow was diagram and test everything if you realy want to know whats wrong, but it requires some electrical knowledge…

Yes flashing orange when GPS receiver is connected and panda messages going out. But not flashing fast red!

My bad. It’s flashing orange. Not red. So like how it is now should I have a light on the steer led on the board? Should be white? Because it’s not.
But if I press once the button on teensy, orange blinking stops, red flashing starts and same time the white light on the steer lights up. I guess either teensy or pcb something wrong or did a short or something. Because two days ago for whatever reason it connected the steering. And then I tried to connect on pin 8 and gnd the cable to do remote activation from button. And after it didn’t work anymore next day.

I am not able to help here, as I have no new PCB type. Am still using pcbv2 and panda.

When you press that it enters flashing mode… code stops. Did you use configomatic to flash firmware, you could repeat it but dont press that button after it

I knew it was orange, I grew up with my dad saying “oh shit we are low on fuel theres red light flashing” for 10 years and when I started driving I realised its yellow light. :joy:

watch the serial monitor during Teensy Start Up, before panda messages will be started, it will do some inititialization where you can see if the ADC is detected and found or not.

In case you have fried onboard ADC you can remove it and use an external one, but better check each belonging part with the multimeter before.

Did you check other inputs like steering switch …

Try measure voltage direct at ADS header A0 / GND (… WAS_H_2)

Check also VDD / GND, SCL / GND, SDA / GND (… supposed 5V)
