I´m reading out positions of an eGalax USB capacitive touchpanel in Pure Data. This see-through touchpanel is basically a capacitive touchscreen without screen. The 17" touchpanel is being read as USB mouse device as soon as connected to the RPI4.
I am using the xy position to drive parameters of a PD sound-patch. The panel is needed for it´s transparency, other than that it´s just an xy-controller like a joystick.
The patch so far gives me access to the xy-mouse/panel readouts and on a lower level also the readout of the HID raw bytes data - exclusively for this particular panel, so this might make it less dependent of being recognized as usb mouse, not sure...
My problem is the mouse click. When expressively scrubbing around :~0 it's leading to rearranging click&drags and random menu interactions. Ideally I would get rid of the global mouse function all together - have it as basic usb device in PD - but I imagine simpler changing the config to disable the click for the device so it can´t mess around. Can't figure it out, I´m stucked and without programming skills. Can this be done?
I'm running Patchox OS based on Raspberry Pi OS Lite - willing to change OS. Thank you.
