GPIO 引脚在不应该忙的时候忙

如何解决GPIO 引脚在不应该忙的时候忙

我在 python 中使用 lgpio 并创建一个项目，该项目允许我使用 Flask REST API 控制一些 gpio 引脚。出于某种原因，当我在没有烧瓶的情况下运行代码时，gpio 引脚工作得很好，但是一旦我添加了烧瓶，一切都会走下坡路。这是我的代码和错误，如果有人可以帮助或指出我正确的方向，那将是惊人的

import lgpio,time
from flask import Flask,jsonify,request
from flask_restful import Resource,Api


# creating the flask app
app = Flask(__name__)
# creating an API object
api = Api(app)

switchDown = 23
switchUp = 22
led1 = 20
led2 = 21

h = lgpio.gpiochip_open(0)
lgpio.gpio_claim_input(h,switchUp)
lgpio.gpio_claim_input(h,switchDown)
lgpio.gpio_claim_output(h,led1)
lgpio.gpio_claim_output(h,led2)
#debugging trying to figure out why gpio is in use
print(lgpio.gpio_get_chip_info(h))
print(lgpio.gpio_get_line_info(h,switchUp))
print(lgpio.gpio_get_line_info(h,led1))
print(lgpio.gpio_get_mode(h,switchDown))
print(lgpio.gpio_get_mode(h,switchUp))
print(lgpio.gpio_get_mode(h,led2))

class test(Resource):
    if lgpio.gpio_read(h,switchUp) == 1:
        lgpio.gpio_write(h,led1,1)
        time.sleep(5)
        lgpio.gpio_write(h,0)
    elif lgpio.gpio_read(h,switchDown) == 1:
        lgpio.gpio_write(h,led2,0)
    else:
        lgpio.gpio_write(h,0)
        lgpio.gpio_write(h,0)

# adding the defined resources along with their corresponding urls
api.add_resource(test,'/')


# driver function
if __name__ == '__main__':

    app.run(debug = True)

打印语句的输出“ [0,58,'gpiochip0','pinctrl-bcm2711'] [0,22,1,'GPIO22','lg'] [0,20,3,'GPIO20','lg'] 257 257 515 515"
