功能相关函数

power_expand_board.set_power(ch, pwm)

设置直流电机以指定动力转动，开环控制，参数：

• ch 通道，直流电机通道/电磁阀通道为 "CH1" ~ "CH8", 无刷电机通道为 "BL1" ~ "BL2"。
• pwm 转速，单位为 无，范围 -100~100， 当设置电磁阀断电时pwn为0，当设置电磁阀通电时pwm为100。

power_expand_board.stop(ch)

使直流电机/无刷电机停止运转，参数：

• ch 通道，直流电机通道为 "CH1" ~ "CH8", 无刷电机通道为 "BL1" ~ "BL2"， 所有通道为 "ALL"。

程序示例：

import novapi
from mbuild import power_expand_board

while True:
  time.sleep(1)

  power_expand_board.set_power("DC1",100) #直流电机
  power_expand_board.set_power("DC2",100)
  power_expand_board.set_power("DC3",100)
  power_expand_board.set_power("DC4",100)
  power_expand_board.set_power("DC5",100)
  power_expand_board.set_power("DC6",100)
  power_expand_board.set_power("DC7",100)
  power_expand_board.set_power("DC8",100)
  power_expand_board.set_power("BL1",100) #无刷电机
  power_expand_board.set_power("BL2",100)
  time.sleep(2)

  power_expand_board.stop("DC1",100)
  power_expand_board.stop("DC2",100)
  power_expand_board.stop("DC3",100)
  power_expand_board.stop("DC4",100)
  power_expand_board.stop("DC5",100)
  power_expand_board.stop("DC6",100)
  power_expand_board.stop("DC7",100)
  power_expand_board.stop("DC8",100)
  power_expand_board.stop("BL1",100)
  power_expand_board.stop("BL2",100)

  #电磁阀1设置为断电
  power_expand_board.set_power("DC1",0)
  time.sleep(2)

  #电磁阀1设置为通电
  power_expand_board.set_power("DC1",100)
  time.sleep(2)

  #停止所有电机
  power_expand_board.stop("ALL")
