网购的usb转gpio模块

import sys
from sys import argv,exit
from pygpio import BaseGPIO as GPIO

IN1 = 1
def setup_gpio():
GPIO.setup(IN1, OUT)

if name == 'main':
app = QApplication(sys.argv)
setup_gpio()
sys.exit(app.exec_())
出现如下报错
File "D:\lpcj\Qt-Camera\lpcj3.py", line 166, in setup_gpio
GPIO.setup(IN1, OUT)

NameError: name 'OUT' is not defined

打开gpio.py文件，有内容如下

在源码中OUT有定义和赋值，即OUT=0，在你的代码中缺少这行。添加上去运行试试。

加一行from pygpio import * 试试
