5V Voltage - Bad: 1.94

[Vic]

Hi,

As mentioned earlier, I've been working on a pypilot installation of my own design. And I am wel underway. Earlier (with no motor controller hooked up yet), i've got and error message in the web interface. Saying that there is a low voltage. And totday, with the motor controller hooked up, i've gotten this same message also in the display.

Does anybody know where this voltage is measured? And were I should look in my schematics?

That message basically means it is trying to measure the 5v of the raspberry pi and getting a bad reading...

I have no idea how you wired stuff up, but did you connect an arduino over spi to the raspberry? It looks like you hacked something. If you are using the hat.ino sketch it will expect a resistor divider on ADC6. See:

Ah, great!.
I totally missed that voltage divider.
It work now.

Thanks for the quick reply!
