Hello,
I have written a GUI for my program using tkinter, and will be using this program to interact with the GPIO pins (buttons turning on/off LED's). After doing some research I have found that the solution to this is using the pigpio library.
I am new to programming, so to me this seems like a "workaround".
Is this the accepted method of being able to interact with GPIO pins using buttons on a GUI application? Why can't we just tell the raspberry pi that the application has sudo privileges somehow?
Any info would be helpful!
Thanks!
Matt

Re: Concerns with using pigpio
There is no one true method, but pigpio is a perfectly valid one. There's also wiringpi, the sysfs interface and many others. There are advantages and disadvantages for each method, but for your use case, it shouldn't matter which you use.mattg31 wrote: Is this the accepted method of being able to interact with GPIO pins using buttons on a GUI application?
You can, but the idea is to compartmentalise things and not give more access than an application requires. Running the whole thing as root is not a good solution.mattg31 wrote: Why can't we just tell the raspberry pi that the application has sudo privileges somehow?

ok, thanks for the reply @ShiftPlusOne !
Re: Concerns with using pigpio
When I started on the Pi, it was nice not to have to use sudo to run a program just to access them.
One advantage pigpio (well pigpiod) does give you is you can run the GUI on something else other than the Pi. No idea if that is true for the other methods.
