QUESTION

no mouse movement or touch in kivy app run from cli in raspberry

Asked 2021-Jan-19 at 09:11

I'm just starting with Kivy - I have issues getting the mouse and (multi)touchfunctionality to work. Setup: RPi 3b v1.2, Raspberry os buster 5.4 with desktop & python 3.7.3, using Waveshare DSI touch display Waveshare display drivers were installed: https://github.com/waveshare/LCD-show

Kivy is installed in virtualenv, which I start with source /home/wannes/kivy_venv/bin/activate ('wannes' being my username) Kivy examples are in ~/.local/share/kivy-examples/demo/showcase

I've added this to ~/.kivy/config.ini:

Found the solution. First, the waveshare driver has to be setup with the pi user and not any other - in their driver setup files the user pi is hardcoded... Then, the user (other than pi) with which you want to run the Kivy apps, has to be member of the 'input' group: sudo usermod -a -G input $(whoami) Kivy needs access to /dev/input/event0 /event4 and /event5 Waveshare setup give only the pi user access to the input group, which has read access to those devices. Problem solved - at least there is little documentation from Waveshare for setup of their touch driver.

QUESTION

Troubleshooting a script for my RPI to toggle displays

Asked 2018-Sep-20 at 02:19

So I have a Quimat LCD attached to my gpio.

included is a script which runs to switch to the display (LCD35-show), and another to switch back to the HDMI port (LCD-hdmi). This causes a reboot when done so any variable changes have to happen prior to this.

as this is for my mother who is afraid of touching command prompt, I am trying to set up a single icon to use to switch between video sources.

I am a novice at coding, most of my experience from dabbling in BASIC, and have spent a couple days searching and trying to set this up, but apparently am failing at how to search properly as I couldn't get it functioning.

What I have done so far is this:

Created text file state.txt to hold a variable stating what mode the device is in (HDMI or LCD)

My attempt was to read the variable, then use if then statement to determine which file to run, change the variable then run the file.

This is the code I ended up with.

Be careful with your bash script comparisons. Wrap strings in quotes (or some other method), so it's not a syntax error when string-vars evaluate to empty. You can use == for string comparisons in bash, but = works in bash and sh.
