We're trying to get our bq40z60 up and running with bqStudio. We're finding it particularly difficult to get the learning cycle going. Is there a "learning cycle guide" available?
The main annoyance is that bqStudio's names for registers do not always line up exactly with the names printed in the reference manual. To make matters even more confusing, the register locations given in the advanced view do not line up with anything that I can find in the reference manual.
For instance, RDIS must be set to enable the learning cycle. However finding where I can set that register in bqStudio has taken more time that I care to admit and I still struggle to find it on subsequent runs.
Once the learning cycle claims to have started, the output FETs are not enabled. I've been able to enable them in the past with some combination of sending FET_EN, CHG_FET_TOGGLE, and DSG_FET_TOGGLE. Now however even that is not working. It looks like the FUSE output is enabled and preventing DSG/CHG but I cannot figure out why or how to clear it. I've tried sending a "Fuse Toggle" command via 0x001D manually but bqStudio reports communication errors (only for manual SMBus commands).
