    can anyone help me with reading any analog pins off python?

    Traceback (most recent call last): File “”, line 43, in fd = open(file, ‘r’) IOError: [Errno 2] No such file or directory: ‘/sys/class/leds/pwm0/max_brightness’

    What am I doing wrong?

    OS info: Linaro 12.07 (GNU/LINUX 3.4.29+ arm71)
