运行此python脚本，以查看ev3dev上的电源发生了什么。除了注释掉的代码以外，它们还可以作为未知变量报告？

这应该读什么？

#!/usr/bin/env python3
from ev3dev2.power import PowerSupply

power = PowerSupply()
print("amps",power.measured_amps)
print("volts",power.measured_volts)
print("type",power.type)
print("max_voltage",power.max_voltage)
print("min_voltage",power.min_voltage)
#print("measured voltage",measured_voltage)
#print("measured current",measured_current)

Answer 1

您没有定义measured_voltage和measured_current变量。试试这个：

print("measured voltage",power.measured_voltage)
print("measured current",power.measured_current)
