-LEGO MINDSTORMS EV3 Battery
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-LEGO MINDSTORMS EV3 has some built-in capability for monitoring the battery.
-It uses 6 AA batteries or a special Li-ion rechargeable battery pack that is
-detected by a key switch in the battery compartment.
-
-Required properties:
- - compatible: Must be "lego,ev3-battery"
- - io-channels: phandles to analog inputs for reading voltage and current
- - io-channel-names: Must be "voltage", "current"
- - rechargeable-gpios: phandle to the rechargeable battery indication gpio
-
-Example:
-
- battery {
- compatible = "lego,ev3-battery";
- io-channels = <&adc 4>, <&adc 3>;
- io-channel-names = "voltage", "current";
- rechargeable-gpios = <&gpio 136 GPIO_ACTIVE_LOW>;
- };
