Im Gonzalo from Argentina, and together with a couple friends we are developing a product based on raspberry pi4 hardware.
We are developing everything in nodered. We have achieved some quite good advancements, pwm outputs we need for motors are working well, with acceleration ramps, and all other settings done. GPIO management seems correct, and we are about to test the rest of the electronic components interfaced with raspberry. The rest of the programming can be easily done, and though the dashboard options are not great, they are acceptable.
The only issue we are having is that the interface should work in kiosk mode, and the interface hardware is the original 7" screen.
Now this is the thing. We cannot achieve an input as if it were a tablet. I mean the touchscreen works, but as a mouse input, and makes the experience suck.
I´ve been thinking of changing the OS (right now its raspbian), but i think it might happen that all we have achieved with the GPIOs goes to hell.
We have tried not showing the cursos, but we had no success at it.
Has anyone done this? We would like to slide bars, swipe, etc. but right now we cannot do anything like it..
All the threads I´ve found never show a specific answer or solution for this.
