now i am "playing" with navigation.
ELO touch screen (1215L) on the USB port of a HD1010.
5 pages of *.png, all set to "no transition".
P1 has three touch areas, invoking P2 or P3, which both call P4 after a time out. P4 jumps back to P1 after timeout.
P5 is invoked by an incoming UDP command on any of the pages and must be touched to go back to P1.
For testing i have added a "back-to-p1" full screen area to P2 .. P4.
Touch events on P1..3 and P5 react between 1 and 2 seconds delayed, on P4 recation is almost immediate to immediate.
UDP event works immediate from P1, but with about 2 sec delay from P2 .. P4.
Is there anything i can optimize to speed up the touch reaction?
It's going to be an unattended public gadget in the end of the day, so it should react "almost immediate" - since people tend to "touch" multiple and increasingly hard, if something "does not understand" ...
