Mouse with absolute coordinates

[krucho]

Hi everyone!
I've been playing with a RP2040 as HID Mouse with Arduino IDE, but my application needs absolute coordinates. Based on this thread I modified some files and make a basic sketch to work, the problem is, it only works with int8_t for X and Y (-128 to 127), actually from 0 to 127 on the screen.
Is there a way to "upgrade" the X and Y to int16_t or uint16_t without breaking everything?

you can create your own 16-bit report descriptor
