      I am on a m5stickC and I a trying to use the coulomb counter registers to monitor the battery level. I started with https://github.com/m5stack/M5StickC/blob/master/examples/Advanced/AXP192/PowerWake/PowerWake.ino and added M5.Axp.EnableCoulombcounter(); at the end of setup. Then I tried to display the counter output from AXP192::GetCoulombchargeData() and AXP192::GetCoulombdischargeData(). The issue is that no matter what state the USB charger is in it only displays UINT32_MAX. This seems like it's wrong or something is not configured correctly. I was under the impression from the datasheet that you only needed to enable on that register and it was okay. Is there a step missing?
