erratic behavior of P4 tactile screen

[solpie]

Dear GHL,

For some reason, it becomes very difficult to use the touch screen of the P4 ... I have just made an update to firmware 7,18 but still the behavior is arbitrary (some keys work one time out of 3-4)

My P4 is a little more than 1 years old. Is there anything to do ?

Thanks

Can't you calibrate the buttons in GHL ControlCenter?

Thanks a lot for your answers Pit !

I didn't knew this calibration existed ! I tried it and it works better now.

However, I honestly do not understand what I'm supposed to do while the procedure is running (I tried the "Use Own calibration") .... The P4 enters in a funny mode where he enters various menus without any action from myself .... I simply typed all keys as requested in the 1st message while he was going crazy ....

Is that a normal behavior ?

Is that a normal behavior ?
no

The calibration and further information can be found in the PL4 programming manual (https://www.aquariumcomputer.com/downloads/profilux-4-programming-guide-v7-02/).

Sorry, was in the wrong post.
