getBattChargeCurrent() not working ? #31

Closed patrickpollet1966 closed 4 years ago

patrickpollet1966 commented 4 years ago

Dear All,

for a few hours i try to use getBattChargeCurrent() to read the actual charging current. (In fact i want to monitor the charging state by reading the battery voltage and the current)

The issue is that getBattChargeCurrent() always return 0 but the battery is currently charging as the battery voltage increase (and an ampermeter shows me that current is flowing in the battery accordingly with the value i previously set by setChargeControlCur() ).

Did someone already have successful results with getBattChargeCurrent() ? Did i miss something or is it a bug ?

Edit : i use an AXP192 on the T-Beam board.

Best regards.

You must enable the adc register before you can read the adc data

Thanks a lot, it works well now. It was my fault, i have missed this point concerning the activation of the ADCs. I was leaded in mistake because the battery voltage was working without.
