Re: RPI.GPIO and Pi4 issue ?

You can now install the alpha release (for testing purposes):

Code: Select all

$ pip3 install --upgrade --pre rpi.gpio
Let me know if it works or not.

Re: Got the latest Raspbian light image, pip is not installed

That is the download url you get when you search for pip on PyPi. ( https://pypi.org/project/pip/ )
In other words, it is safe.

You can probably 'apt install' it too - I'm not at a computer at the moment to check the command though.

I had the same yesterday. The checksums match up to the raspberrypi.org downloads page so I'm not too concerned.

Re: No access to dev/mem

You shouldn't need root privileges with an up to date version of Raspbian and RPi.GPIO. You have still not answered my questions about the versions of things a few posts earlier. Without this information, we can only guess as to what is going wrong and what the solution is.

Re: No access to dev/mem

* What OS / Distro are you using?
* What username is your Python program running under?
* What version of RPi.GPIO are you using?

Re: No module named flask after installing flask

By using 'sudo' on the pip install command, you have installed Flask globally on your pi, not in your virtual environment. Just install it in your venv by not using sudo.

Re: Unable to install pyzmq and RPi.GPIO from requirements.txt

The latest version of RPi.GPIO is 0.6.5. The version you are trying to install is 0.5.11, which is four years old. This is not your immediate problem however but it shows just how out of date the project instructions are. Things to try: 1) sudo apt install python3-dev 2) Change requirements.txt to r...

Re: GUI opening on the server instead of on the client side...

If memory serves me correctly, there is a X11Forwarding flag in /etc/ssh/sshd_config on your Ubuntu box that might need setting to 'yes'.
Restart your ssh server for it to pick up config changes.

Re: How to make interesting projects with the Raspberry pi 3 using the Ada language?

If you use 'gnat' (the Ada compiler) then controlling GPIO is as simple as writing to /sys/class/gpio/... using standard file i/o in Ada.

Re: Exceptions on threading

It's because you are using GPIO.setmode(...), GPIO.setup(...) and GPIO.cleanup() in your thread. Move these to the beginning and end of your main program.

I think I've fixed it in the latest development RPi.GPIO. It turns out that the GPIOs weren't getting cleaned up properly under Thonny and a recent bugfix to RPi.GPIO unmasked the problem. I will release RPi.GPIO 0.6.5 in the next few days. If you can't wait that long then install the latest develop...
