# 配置

  1. Enable UAVCAN by setting the UAVCAN_ENABLE parameter to 2 (Sensors Automatic Config) or 3.
  2. Set the following module parameters using the Mavlink console (opens new window):
    • Battery capacity in mAh: battery_capacity_mAh
    • Battery voltage when full: battery_full_V,
    • Battery voltage when empty: battery_empty_V
    • Turn on current integration: enable_current_track
    • (optional) Turn Off CANbus termination resistor :enable_can_term

Example: A Power Module with UAVCAN node id 125 connected to a 3S LiPo with capacity of 5000mAh can be configured with the following commands:

uavcan param set 125 battery_capacity_mAh 5000
uavcan param set 125 battery_full_V 12.5
uavcan param set 125 battery_empty_V 11.2
uavcan param set 125 enable_current_track 1
uavcan param save 125
