Python 操作GPIO

    为了大家使用方便,这里同时提供了pyhton的gpio库:lpi_gpio.so

    接口名与C的函数库相同,这里是一个简单的使用示例:

    ~~~~ {.sourceCode .Python}
    import lpi_gpio
    import signal
    import time

    def exit(signum, frame):
    lpi_gpio.deinitlib()
    print('exit test_gpio')
    exit()

    signal.signal(signal.SIGINT, exit)
    signal.signal(signal.SIGTERM, exit)

    lpi_gpio.initlib()
    lpi_gpio.init(6,0,1,0)
    while True: #闪烁PG0 绿灯
    lpi_gpio.w(6,0,0)
    time.sleep(0.5)
    lpi_gpio.w(6,0,1)
    time.sleep(0.5)
