i'm fighting with the touch calibration of a waveshare Pico-ResTouch-LCD-3.5 display.

As the gui calibrate command gives an error-loop most the time, even when just briefly pecking at the display, at last i managed to get a complete run though. The result was in error, but the next attempts seem to run smooth, no hastly pecking needed. By playing around i found out that the gui calibrate command takes some arguments, appearently the same as one sees in option list for the touch calibration.

I there any descrition of the arguments, what do they represent? Searching throu the manual and the forum reveals a lot of topics/issues with gui calibrate but no answer to my question.

many thanks in advance,
