Re: rpi touchscreen+display but from command line

I confirm what you guys have written. The touchscreen input is usually created as event0 But if a mouse or keyboard is plugged, this can be different. Pending: online guess the device filename to use. Using SDL + GUIslice library, i was able to remotely start the program, show the canvas on the disp...

Re: rpi touchscreen+display but from command line

What programing languages do you know maybe we can point you to something else. C/C++ will be the choice here . because of background and past projects I am confident enough to write a small GUI SDL seems like a nice starting point. Another possibility is using this library and its helper GUI build...

Re: rpi touchscreen+display but from command line

just a small update for the interested. pygame is good enough to create a simple GUI and it doesn't need X server running (as it uses SDL libraries to write directly to framebuffer if i'm not mistaken.) ; however i believe this solution is too "bloated" (cpu and memory intensive) so i will be explor...

Re: rpi touchscreen+display but from command line

If these screens works with the scripts you linked to then I think they will be available under /dev/input. So you should be able to test your screen with the "evtest" program and read the input using the Linux evdev api. https://python-evdev.readthedocs.io/en/latest/ https://www.freedesktop.org/wi...

Hello, long-term user of rpis here. To make a long story short, i have one of these: https://i.postimg.cc/g2zhqjy5/img000.jpg There are some tutorials for it, most of them assume you want to use touchscreen alongside raspbian desktop.

But is it specific to that particular GPIO pin only? Are you using other GPIO pins, but not seeing the warning message for those? Is you program exiting cleanly with GPIO.cleanup() . You may notice that if you reboot the pi, run your program, and find that it does not show the warning, but if you t...

Real outdoor mics are kind of expensive. Sensitive mics can't stand moisture. The Zoom suggestion might be your best bet. But everything depends on what you're trying to do. You also need to take into account the RPi doesn't have sound input. So you need a USB audio interface. And one that works wi...
