Some GPIO pins don't work. Using python-rpi.gpio

yehnanyehnan Posts: 16New Member
Hi,
I'm following the example "Blink an LED on a GPIO output pin"
in this document: https://up-community.org/wiki/RPi.GPIO

The example uses pin 4 (in the arragement of GPIO.BCM) to control LED.
No problem with that.

But if I changed to pin 27, 22, 23, 24; then the LED won't blink.

If I changed to pin 2, 3, 14; the LED will blink.

Why?

    After trying all examples in
    https://up-community.org/wiki/RPi.GPIO

    I found that some pins won't work for some functionalities.

    Is the UP board(Ubilinux)'s implementation of RPi.GPIO(python-rpi.gpio) complete?

    we have updated the library which is currently under testing internally.

    It will be available in the coming weeks.

    Is there an estimated release date?

    if you run an upgrade now you will download a newer version with the fixes implemented.

    Let me know if you might have any feedback!

    just installing linux now (the windows api is too far from complete)

    does it have PWM (even if only the rpi.gpio software version) working?
