Im getting the same warnings - VdcHighFLDBK and also VdcLowFLDBK.
If your battery voltage isn't actually outside the foldback thresholds, this probably means that the "start" and "end" parameters are set to the same value. This is a common issue with the foldbacks in the ASI controllers - by default the start and end are the same, but this condition causes a warning. Note that these warnings won't actually affect the functioning of the controller, they're just annoying. But to clear them, just make sure the start and end are set to reasonable values, and that these values are different.
For example, if you want the controller LVC to be 39 V (3 V * 13s), set the low voltage foldback end to 39 V and the start to something like 44 V.
For something like low SOC foldback, which you probably don't even want to use, set the start to 1% and the end to 0%.
But I cannot get it to connect to the pc at all
I've never had trouble connecting, but here are some things to check:
- You're using a 5 V USB-TTL adapter, not 3.3 V
- Only GND, RX, and TX are connected
- Adapter RX connected to controller TX, and vice versa
- Look at the available COM ports before and after you plug in the adapter, and make sure you're using the one that's new.
- Use a serial port monitor program to look at the traffic. If there's nothing incoming, it could mean the controller's comms chip is faulty.
