在调试的过程中,发现一直有电流存在,导致系统判断为充电或放电,这个电流是怎么产生的,是否为元件损坏造成的。
您好, It is not unknown that LEDs draw current. I see that there's a 100Ohm resistor in the LED path, see below for the EVM schematic. The 100 Ohm might be current limiters, but could be dissipating power.
What can be done is increase the Deadband to 50mA. This will inform the gauge to report 0mA for current less than 50mA. It has no gauging effect since the coulomb count will reset as I see the current going positive and negative, so the accumulated charge cancels out.
Calibration | Current Deadband | Deadband | 3 | mA | U | 1 | 792 | 3 | 0 | 255 | ddd | x+0 | x | mA | 0x03 |
