We are tring to builrd an electric go kart using a focbox unity with two pedals, one for ghrottle and one for brake, and the adc2 pin has not been working. We have have two pedals one connected to the adc1 port that is working, and another connected to the adc2 port that is not. The first thing we did was try to find all the possible problems. We know the pedals are both working because we switched the pedals and only adc1 works, we know it isn’t the focbox because we tried another one and still had the same problem. We also tried using 3.3 and 5v and neither worked. In the app configuration page it shows adc2 with zero volts while adc1 shows a voltage. We also tried downgrading to an old VESC Tool software and firmware and that doesnt work. We’re in desperate need of help if anyone knows a possible fix.
Thanks for the video. We did exactly what he did and still to no avail. The only difference is were using a focbox unity while hes using a normal focbox.
share a picture of the setup
Here is a picutre of the pedals connected to the 7pin jst that goes into the focbox unity. It look like a mess right now because we were testing that all the pedals worked and that the solder joints were good but that wasnt the issue. I also included a circuit diagram of how we have everything connected to make it a little more clear. Thanks for the help!
Remember to use pull down resistors at the Vesc so if the throttle gets disconnected it won’t go full throttle on you.
Just curious if you have any idea of the issue?
