  • Any one getting this error for reading analog pin infos? /sys/class/leds/pwm0/max_brightness that the directory is empty.


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

    using Linaro 12.07 (GNU/Linux 3.4.29+ armv71)

  • I have entered simple analog input and output program, and i been keep facing error saying:

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

    code is python code(https://learn.sparkfun.com/tutorials/programming-the-pcduino/analog-input-and-output)

    What am I doing wrong?

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

  • if you are trying to have multiple pressure sensor to a single board, what would you do in wiring?

No public wish lists :(
