【Openmv和arduino】电平编码通信

Openmv：

from pyb import Pin
import time

value=[0,0,0]

p_in_0 = Pin('P0', Pin.IN, Pin.PULL_UP)#设置p_in为输入引脚，并开启上拉电阻
p_in_1 = Pin('P1', Pin.IN, Pin.PULL_UP)#设置p_in为输入引脚，并开启上拉电阻
p_in_2 = Pin('P2', Pin.IN, Pin.PULL_UP)#设置p_in为输入引脚，并开启上拉电阻

value[0] = p_in_0.value() # get value, 0 or 1#读入p_in引脚的值
value[1] = p_in_1.value() # get value, 0 or 1#读入p_in引脚的值
value[2] = p_in_2.value() # get value, 0 or 1#读入p_in引脚的值
while(True):
    print('value=',value)##000为arduino输出高电平
    time.sleep(2000)
